Abstract：To the lack of input and output tracking,complete reliance on manual operation,and low work efficiency control system in a 900 mm hot rolling line push type heating furnace,this article proposes a new automatic steel loading scheme in front of the furnace and upgrades it.By adding a laser rangefinder and control logic,automatic positioning of the slab on the furnace roller conveyor can be achieved.By adding laser rangefinders and pressure sensors to monitor the real-time position of the pushing head and changes in hydraulic cylinder oil pressure during the forward and backward processes of the steel pusher for the mixed loading of slabs of different widths,and improving the algorithm based on the mixed loading of slabs,automatic steel loading is ultimately achieved.This scheme can greatly improve the automation level of slab feeding into the furnace,accelerate the production pace,and achieve the goal of increasing output.
