In a method for producing a spray nozzle device, in particular for spraying a casting strand during casting of metallic products, the spray nozzle device includes a basic body with an air inlet, a water inlet and a nozzle body with a mixing chamber for producing an air/water mixture which emerges through at least one nozzle outlet. The air inlet is formed by at least one air inlet nozzle, with a nozzle tip projecting into the mixing chamber, and has at least one air outlet hole. The water inlet opens into the mixing chamber close to the nozzle tip of the air inlet through at least one water outlet hole oriented transversely to a longitudinal axis of the mixing chamber. At least one part region of the spray nozzle device is produced by a generative production process, preferably operating as a 3D printing process.
In a process for continuous or semicontinuous strand casting, especially in a vertical casting plant for casting steel, the strand (5), at the end of the casting process, is withdrawn downward in a cooled mould (1) after the melt supply has been stopped. The strand (5) is stopped before the fill level (15') reaches the lower end of the mould (1). The lower end (2') of a pipe element (2) is immersed into the metal melt in the mould (1) in such a way that the fill level (15') of the metal melt rises nearly as far as the upper end of the mould, as is the case during the casting process. This simple procedure enables better output rates owing to the shorter upper end of the strand that has to be cut off.
A forging press for rotationally asymmetrical parts by warm or hot forming has a stationary press table, a vertically shiftable press ram above the press table, vertically delimiting with the press table a working space, and vertically displaceable between from an upper open position into a lower closed position. An upper part is carried by the ram in the space, and an upper die in the space is in turn carried on the upper part. A lower part sits on the table in the space and below the upper part and carries a lower die in the space and fittable with the upper die in the closed position. A first closing apparatus outside the space bears vertically on one of the dies, and a second closing apparatus outside the space bears vertically via the first closing apparatus on the one die.
A tube or metal extrusion press has a stationary press frame formed by a main housing, a counter housing, a billet support carrying a billet holder, and a ram cross-member movable in the press frame between the housings. A piston-cylinder unit has a cylinder on the main housing, a piston in the cylinder, and a ram stem extending between a front end of the piston and the ram cross-member. An equalizing reservoir supplies hydraulic fluid to the piston, and a transfer passage extends between the reservoir and the cylinder rearward of the piston. A fill valve has a displacement sleeve on a rod and carries a ring piston and a fill valve body movable centrally of the cylinder in the transfer passage between an open position in which the passage has a large annular flow cross-section and a closed position in which the valve body blocks the passage.

The air/water mixture is produced in a mixing chamber which acts as a diffusor and includes an air inlet, a water inlet, and a nozzle outlet approximately in alignment with the air inlet. The air inlet is arranged in an air inlet nozzle, the tip of which protrudes into an upper region of the mixing chamber and preferably has air outlet holes oriented perpendicular to a longitudinal axis of the mixing chamber. Water enters near the tip through at least one water outlet hole oriented perpendicular to the longitudinal axis and placed such that the water jet exiting the water outlet hole flows past the air outlet holes. The air flow or air pressure and the water flow or water pressure do not influence each other.
The invention relates to an ingot mould (2) for continuous casting of steel and similar materials, having a plurality of actuators (5a to 5d), which are arranged distributed around the circumference, generate vibrations directed transversely to the longitudinal axis of the ingot mould, and are synchronised to each other in terms of phase such that the vibrations move along the inner wall of the ingot mould (2) in a wave-like manner from top to bottom. The transversely directed vibrations minimise the friction between the cast strand and the ingot mould and in addition produce a downwardly directed displacement force on the shell walls of the strand. Transport of the strand within the ingot mould (2) is activated thereby, and the casting process is thus considerably supported and consequently improved.

EXTRUSION PRESS AND METHOD FOR CONTINUOUSLY PRESSING METAL
The invention relates to a continuously operating extrusion press (1), comprising a main pressing plunger (12) active in a receiving element (15), a preferably hollow counter pressing plunger (33), and a storage chamber (24) for metal pressing material, wherein said storage chamber can be blocked by means of the receiving element (15) and is operatively connected to the counter pressing plunger (33), and wherein the main pressing plunger (12), the counter pressing plunger (33), and the pressed pressing material can be moved horizontally. In order to enable the continuous pressing of metal, wherein by means of said extrusion press a continuous profiled element that is as uniform as possible can be continuously produced, the operative connection of the storage chamber (24) to the receiving element (15) and to the counterpunch (33) can be blocked under actuation by means of the pressing material.
Mold for the continuous casting of preliminary sections, in particular double T-shaped preliminary sections, such as beam blank sections or similar sections, wherein all the interior walls of the mold in a mold passage have a tapered course running linearly from top to bottom, this tapered course being dimensioned depending on the degree of shrinkage of the cast strand and produced by machining the interior walls. In this manner, it is possible to optimally adjust the diameter of the mold to the shrinkage process of the cast strand in the region of the mold passage, even for large-sized sections.
Continuous casting moulds used in automated installations casting metal melts into strands require comprehensive, reliable real-time monitoring. Currently used systems are susceptible to damage and limited to just a few sensors, as arrangements involving a higher number of sensors have proven impractical due to the substantial effort they cause when exchanging a mould. To overcome this obstacle it is suggested to use wirelessly interrogable passive surface acoustic wave (SAW) sensors for monitoring of physical parameters in continuous casting moulds, and install at least one wireless link section in the signal path between SAW sensors and their reader devices. Continuous casting moulds thus become easily exchangeable with their sensors installed, making it industrially practicable to equip continuous casting moulds with a significantly higher number of sensors than previously feasible.

A drive for a roll stand having a reciprocal frame, has a pair of substantially identical cranks rotating about respective crank axes offset from the frame, respective connecting rods pivoted on and connected between the cranks and the frame, and respective counterweight on the cranks opposite the respective arms. The cranks, rods, and counterweights flank a central plane. Respective drives rotate the cranks about the respective axes in opposite rotational directions.
The invention relates to a method and a rolling mill for producing a seamless steel pipe in a continuous rolling process, where semi-finished material is first formed into a hollow block (8) in a rotary rolling mill, said block then being rolled in a multi-tooled continuous rolling mill (1) over a previously inserted mandrel (10) to form a tube blank (9), wherein the mandrel (10) receiving the hollow block and held by a mandrel holding and transporting device (5) disposed on the entry side is fed into the continuous rolling mill (1) and is transported back to the entry side after the tube blank has been rolled off of the mandrel (10) on an extracting rolling mill (4) connected downstream of the continuous rolling mill. An aim of the invention is to allow high production rates at the same product quality, particularly at a low drop in the temperature of the tube blanks. The aim is achieved in that the mandrel (10) with the tube blank (9) is released by the entry-side mandrel holding and transporting device (5) after exiting the last tool (2.n) of the continuous rolling mill (1) and thus is transferred to an accompanying second mandrel holding and transporting device (6) connected downstream and held by the same until the tube blank (9) is rolled off by means of the extracting rolling mill (4).
The invention relates to an automation unit in conveying installations, comprising means for power transmission and for data transmission between or from a fixed power rail and or to a mobile transportation unit, and also means for detecting and determining the position of the mobile transportation unit relative to the distance covered. The aim is to provide an automation unit which, besides having greater operational and functional reliability, reduces the amount of investment and fitting involved, in particular. To this end, the power rail (12) is in the form integrated with the means for data transmission (16) and position finding (17), which have associated counterparts on the mobile transportation unit (8; 8 a, 8 b) for power acceptance, signal/data transmission and position detection.
The invention relates to a continuous casting system, particularly for long steel products, having a gravity die wherefrom a cast slab (2) is continuously cast. The cast slab (2) is formed along a guide track formed by guide rollers disposed one after the other (11, 12, 13, 14), particularly a curved guide track, and substantially fed into a cooling chamber having spray heads. The guide rollers (12, 13, 14) and/or the spray heads are present in a plurality of centering modules (10) or spray modules (3) disposed one after the other, and can be adjusted substantially concentrically to the target axis of the cast slab. The risk of thermal overload of the rollers and of damage to the slab surface is thereby significantly reduced, and the symmetrical cooling is also ensured.
In a process for producing steel long products by continuous casting of steel to form billet and bloom strands (5) and subsequent rolling of said billet and bloom strands, the liquid steel is cast in a continuous-casting permanent mould (3). The cast billet and bloom strands (5) are fed substantially without subsequent heating directly to a roll train (20). This makes the design of the plant more simple, and more cost-effective operation is made possible.

CASTING DIE FOR CONTINUOUS CASTING OF BLOOMS, SLABS, AND BILLETS
The invention relates to a casting die for the continuous casting of blooms, slabs, or billets, having a die tube (2) and a support shell (4) surrounding the tube. The die tube (2) is supported on the support shell (4) by support profiles (15) which are distributed around the periphery and which run in the longitudinal direction of the tube, and is positively connected to the support shell by connection profiles (20) which extend in the longitudinal direction. The connection profiles (20) are each designed as profile strips (21, 22) which extend outward from the outer periphery of the die tube (2) and inward from the inner periphery of the support shell (4), and which engage in each other in such a manner that a play is created in the peripheral direction of the die. The invention thereby substantially avoids tension caused by thermal expansion, lasting deformation, and fatigue cracks.
METHOD FOR IDENTIFYING SURFACE CHARACTERISTICS OF METALLURGICAL PRODUCTS, ESPECIALLY CONTINUOUSLY CAST AND ROLLED PRODUCTS, AND A DEVICE FOR CARRYING OUT SAID METHOD
The invention relates to a method for recognising surface characteristics of metallurgical products, especially continuously cast products and rolled products. According to said method, a defined section of the product surface (12, 12') is irradiated by at least two radiation sources of different wavelengths, from different directions, and the irradiated surface section is optoelectronically detected. Three light sources (21, 22, 23) are oriented towards the product surface (12, 12'), as radiation sources, under the same angle (α), the positions thereof being in three planes (E1, E2, E3) forming a 120° angle and being perpendicular to the product surface (12, 12'). In this way, instructive information about metallurgical products can be determined and stored in a very short space of time such that the products can be determined in a perfectly identified manner for the reprocessing, in terms of the surface quality or surface structure thereof.

One of a pair of rolls of a roll stand is formed with an axially throughgoing central hole through which passes a drive shaft having a pair of ends. A coupling at one end of the drive shaft rotates same and the one roll. This one roll can be shifted, normally vertically, between a use position closely juxtaposed with the other roll and a change position spaced away from the other roll and with the roll resting on supports. An entrainment fitting on the carriage can fit with and axially connect to an entrainment element of the drive shaft in the change position of the other roll. An actuator can shift the carriage from an inner position into an outer position and thereby pull the drive shaft out of the one roll and leave the one roll resting on the supports.
A rolling-mill cooling unit has a cooling-unit conveyor transporting fanned-out loops of wire in a transport direction toward a coiler spaced downstream from the cooling-unit conveyor and serving to organize the fanned-out loops of wire into coils or bundles. A feeder conveyor extending in the direction has an upstream end juxtaposed with the cooling unit and a downstream end juxtaposed with the coiler and is operable to advance the loops of wire from the unit to the coiler. The entire feeder conveyor can be shifted relative to the coiler and to the cooling unit in the direction so as to displace the upstream and downstream ends relative to the cooling unit and coiler.
In a wire rod mill, the last rolling block or unit, either a finishing unit or a postfinishing rolling unit, with common drive is not used for traction control, but traction control upstream thereof is provided to regulate the cross section of the wire rod strand before entry into the last stage. The product is a wire rod strand of low cross sectional tolerance and high uniformity over the length of the rod.
