A Model Trajectory Based Method for Accelerating Steel Loading in Stepping Stove
A stepper heating furnace usually uses a stepper furnace to load cold steel billets into the discharge machine and remove hot steel billets from the furnace,and then send them to the roughing mill for rolling through the discharge roller conveyor.The rolling speed of the rolling mill is fast,and there are high requirements for the loading speed and efficiency of the furnace area loading machine.By analyzing the steel loading sequence and the equipment process of the heating furnace and the front roller conveyor,the limiting conditions for the speed increase of the steel loading machine were identified,and a model trajectory control scheme for electro-hydraulic synchronous control was proposed.By optimizing the electrical control model and automation program,the loading speed of the heating furnace steel loader was improved,and the fuel cost of heating furnace production was saved,ultimately achieving the goal of improving the working efficiency of the heating furnace.
