The invention relates to a strip steel welding seam positioning system and method, belongs to metallurgical automation control, and particularly relates to automation control of a cold rolling processing line. By means of the strip steel welding seam positioning system, welding seams of previous strip steel and next strip steel are moved to width notcher center line from a welding machine center line. A control system comprises a processer, a tightening roller, an unwinding machine and a loop generating device. The tightening roller and the unwinding machine are used for winding the two ends of the welded strip steel. The processor controls the tightening roller and the unwinding machine to rotate so as to change the positions of the welding seams. The loop generating device is used for generating loops and sending the loop size to the processor. According to the strip steel welding seam positioning system and method, the tensile length of the loops and the distance between the welding machine and a width notcher are accurately measured, and the welding seams are accurately positioned to the position of the width notcher.
Description
technical field [0001] The invention belongs to the automatic control of metallurgy, in particular to the automatic control of a cold rolling processing line. Background technique [0002] Welding machine is the key equipment of cold rolling continuous galvanizing line and continuous annealing line. Its function is to weld the front and rear strips together to ensure the continuous operation of the production line. In some welding steps, before the welder is welded, the front strip is required to be covered with a tens of centimeters behind the welder, which is to meet the requirements of welding or re-welding. After the welding is completed, remove this sleeve, and run the strip weld exactly to the position of the crescent shear behind the welder. How to eliminate this looper and accurately position the weld to the position of the crescent scissors is a key control issue. Some methods currently used to eliminate loopers have an impact on the accurate positioning of the we...
