[0039] Such as figure 2 As shown, the specific control process of the present application is as follows:
[0040] Step 1. The laser displacement sensor at the discharge end of the heating furnace sends laser pulses in real time to detect the position of the slab. When the walking beam sends the slab to the exit of the heating furnace, the laser displacement sensor at the discharge end of the heating furnace detects the slab and heats it. The laser displacement sensor at the discharge end of the furnace is switched on, and the walking beam continues to walk in order to complete the running stepping cycle. At the same time, the first-level computer L1 reads the data measured by the laser displacement sensor at this time.
[0041] Step 2: After the walking beam runs, the first-level computer L1 reads the data measured by the laser displacement sensor again, calculates the overflow amount of the slab running beyond the position of the laser displacement sensor, and uploads the po...
