Continuous casting ladle final casting control system based on ladle discharged slag detection system and process control method

Abstract

The invention provides a continuous casting ladle final casting control system based on a ladle discharged slag detection system and a process control method and belongs to the field of continuous casting machines and process control. A discharged slag detector of the continuous casting ladle final casting control system is arranged on an upper water gap of a ladle. A ladle sliding water gap is formed between the upper water gap and a long water gap of the ladle. A discharged slag detection, calculation and control unit is arranged, and the discharged slag detector is connected with the discharged slag detection, calculation and control unit through a discharged slag detection signal processing unit. The discharged slag detection, calculation and control unit is connected with the ladle sliding water gap through a sliding water gap control unit. According to the continuous casting ladle final casting control system, according to optimization of the steel passing speed in the casting process of a casting machine, tundish tonnage control and opening control over the ladle sliding water gap in the later period of ladle casting, optimization of ladle discharged slag detection control, ladle molten steel yield control and tundish tonnage control is achieved; and on the premise of not increasing the labor intensity of operators, controlling the range of influences on casting stability and guaranteeing the quality of molten steel, the yield of the ladle molten steel is increased.

Description

technical field [0001] The invention belongs to the field of continuous casting machine equipment and process control, in particular to a control system for final pouring of a continuous casting ladle and a final pouring process control method. Background technique [0002] With the continuous improvement of the purity requirements of continuous casting products and the continuous development of related equipment, the ladle slag detection system is more and more widely used in continuous casting production practice. [0003] There are three kinds of slag detection systems that are widely used, including electromagnetic induction method slag detection, infrared image contrast method slag detection, vibration method slag detection. [0004] Among them, the electromagnetic induction valve slag detection technology is the most widely used, such as the electromagnetic induction method slag detection technology developed by the German AMEPA company, which accounts for more than 90...
