Control method and device of molten steel pouring

Abstract

The invention relates to a control method and device of molten steel pouring. The method comprises: acquiring data of a mold cavity, total weight data of a steel ingot and total height data of the steel ingot; acquiring a pouring speed curve of a molten steel pouring process according to the data of the mold cavity, the total weight data of the steel ingot and the total height data of the steel ingot; acquiring molten steel parameter information at the former moment and molten steel parameter information at the current moment; calculating the real-time pouring speed at the current moment according to the molten steel parameter information at the former moment and molten steel parameter information at the current moment; and regulating the speed for pouring the molten steel in a steel ladle onto a mold according to the pouring speed curve and the real-time pouring speed at the current moment. By using the control method and device of molten steel pouring, disclosed by the invention, the problems of randomness and instability of production carried out completely by virtue of experience of pouring workers in the steel ingot pouring process are solved, the repeatability and stability of production operation can be realized, the stability and accuracy of molten steel rise in the steel ingot pouring process can be guaranteed, and a guarantee is provided for the precise regulation in the molten steel pouring process.

Description

technical field [0001] The invention relates to the field of molten steel pouring, in particular to a control method and device for molten steel pouring. Background technique [0002] Molten steel is poured by traditional pouring method, the pouring effect and injection speed control are not satisfactory, and in the pouring process, the body pouring is difficult to control and not easy to observe, so the molten steel pouring speed is often too fast or too slow during the pouring process, and the steel ingot The rising speed of molten steel in the mold is unstable, which cannot meet the requirements of pouring steel ingots, resulting in inconsistencies in the internal quality of steel ingots cast from the same furnace of molten steel, and there are large differences, which will eventually affect the quality pass rate of steel ingots, affect the production cycle, cause waste products, and increase production costs. economic loss to the enterprise. With the continuous developm...
