In the process of continuous casting of molten steel production,the oxidant in the continuous casting ladle and impu-rities doped in the molten steel mix to form liquid steel slag.The molten steel containing molten steel and oily steel slag is in-jected from the continuous casting ladle into the intermediate ladle,which seriously affects the quality of the molten steel and reduces the steel yield.This article combines advanced methods for slag detection under steel ladles at home and abroad,and adopts a detection and control method combining electromagnetic induction and steel ladle weighing to explore the automation and intelligent control of slag detection under steel ladles in continuous casting machines.By real-time monitoring of the weight signal of the molten steel and the change signal of the conductivity of the steel slag,after analysis and processing by sec-ondary instruments and industrial control computers,control signals(control slide switch)and alarm signals are issued to con-trol the amount of slag in the ladle,thereby controlling the cleanliness of the molten steel.
