Description

technical field

[0001] The invention relates to the field of steel charging for a regenerative walking heating furnace, in particular to an automatic steel loading control method for a regenerative walking heating furnace. Background technique

[0002] At present, there are generally two ways to control the steel loading of the regenerative walking heating furnace: one is to use a photoelectric switch for positioning control. This control method is to install a photoelectric switch near the furnace door. When the billet head is detected by the photoelectric At the end, after the high-speed running time T1 of the roller table in the furnace, the roller table in the furnace decelerates to a low-speed running time T2 and stops to complete the positioning of the steel billet on the furnace loading roller table. Time T1 and T2 are determined by on-site debugging. Since the billet has different degrees of bending within the allowable range, and the billet slips when the roller ta...
