Method and device for optically measuring a thread
A method and a device can be used for optically measuring a thread on an end of a metal pipe by at least one measuring head which is fastened to a manipulator. The measuring head is preferably freely positionable in relation to the metal pipe and has at least one optical measuring path for measuring the thread and at least one position detector. The method includes at least the following method steps: A) providing the metal pipe in a measurement position; B) determining the spatial position of a longitudinal axis of the metal pipe by means of the at least one position detector before and/or while the measuring head is positioned in a measurement position; C) aligning the measuring head parallel to the longitudinal axis of the metal pipe before and/or while the measuring head is positioned in the measurement position; and D) carrying out the optical thread measurement.

The invention relates to a method for processing a cast strand of metal, in particular steel, comprising the following steps: ● pouring liquid metal into a die in a casting machine for creating the endless cast strand (20) with a starting width (W0); ● compressing the cast strand (20) by means of a compressing device (12) from the starting width (W0) to a smaller interim width (W1) ; and - rolling flat the cast strand (20) by means of a horizontal rolling stand (14), whereby the thickness distribution of the cast strand (20) over its width is evened out after the compressing operation, and the width of the cast strand (20) is increased from the interim width (W1) to a width (W2) after the rolling-flat operation. In order to achieve a desired target width (W2) for the cast strand (20) after the rolling-flat operation in this known method, the method also provides that the compressing of the cast strand (20) is performed to such an interim width (W1) that the desired target width (W2) is obtained as the width of the cast strand (20) downstream of the horizontal rolling stand (14) after the rolling-flat operation - while taking into account the constancy of mass flow and the rewidening effect caused by the horizontal rolling stand (14).
