Abrégé

The present invention relates to a steel coil uncoiling unit, comprising a reel, a strip steel pinch device, a strip threading guide plate, and a support frame. A deep bending roller and a deep bending driving device are provided on the support frame; the deep bending driving device comprises a translation base, a translation driving mechanism used for driving the translation base to horizontally move on the support frame, and a deep bending swing driving mechanism used for driving the deep bending roller to swing up and down; a deep bending roller frame is hingedly connected to the translation base; the deep bending swing driving mechanism is mounted on the translation base and connected to the deep bending roller frame; and a deep bending roller body is provided with a standby position, a deep bending position, and a strip threading position pressed on the surface of strip steel on the strip threading guide plate. Correspondingly, further provided is a steel coil uncoiling method. In the present invention, the deep bending roller has a deep bending function, and can also improve the shape of the head of a strip during strip threading, so that the strip threading efficiency is improved, and smooth production is ensured. In the present invention, the effects of the deep bending roller are fully utilized and explored, so that the deep bending roller has a strip head processing function, thereby reducing the number of field apparatuses and the investment cost, and facilitating the smoothness and safety of production.

Abrégé

A method and apparatus for calculating the height of the root of a cohesive zone of a blast furnace, and a storage medium, which relate to the field of blast-furnace smelting. The method comprises: determining the distribution position of each temperature measurement point on a cooling wall of a blast furnace; periodically acquiring temperature data of each temperature measurement point and preprocessing the temperature data, and removing abnormal values; and performing statistical compilation on a temperature change amplitude and a temperature fluctuation frequency of the obtained temperature data, determining the position of the root of a cohesive zone in a selected direction according to a change in the temperature fluctuation frequency of each temperature measurement point, and calculating a specific height value. In the method, a relatively accurate position of the root of a cohesive zone is effectively deduced according to temperature changes of temperature measurement points on a cooling wall, thereby providing good data support for performing shape calculation on a cohesive zone of a blast furnace.
