CONTROL METHOD AND APPARATUS FOR CONTINUOUS CASTING STEEL POURING

摘要

A control method for continuous casting steel pouring. The method comprises: 1. measuring and reading a ladle casting location signal by using a ladle location sensor (14) mounted on a ladle (1) rotary table; 2. determining in a steel pouring optimization control computer (13) whether the steel pouring of the ladle starts; 3. feeding steel slag measurement data back to an inference controller by using a steel slag measurement sensor (2) mounted above a ladle slide gate nozzle (15); 4. in the inference controller, comparing the read steel slag measurement data with a manually set steel slag value; if the steel slag measurement data is smaller than the manually set steel slag value, returning to a previous step; and if the steel slag measurement data is greater than the manually set steel slag value, outputting and feeding a cylinder control variable to a PI controller; and 5. in the PI controller, comparing a fed-in cylinder location signal with an actually measured cylinder location signal and performing calculation, and outputting to control a cylinder driving unit (5) to push a cylinder (3) to move, so as to make the opening degree of the ladle slide gate nozzle smaller. An apparatus for continuous casting steel pouring using the above control method is further provided. By means of the above method and apparatus, the amount of the molten steel flow of the ladle is controlled, thereby improving the yield of the molten steel and decreasing the production cost.
