Mlc-v235 Continuous Casting Mold Level Control System

Overview Automatic control of the molten steel level in the mold is one of the key technologies in the continuous casting industry. It is very important to reduce the labor intensity of workers, increase production efficiency, improve the quality and yield of castings, reduce overflow and breakthrough of steel, improve the level of management of steelmaking and continuous casting of steel. Molten steel is poured into a mold. To prevent overflow, the level of molten steel must be kept stable. Otherwise, if during the casting process the level fluctuates too much, and the slag will be entrained, forming surface slag inclusions on the surface of the casting workpiece, affecting the quality of the workpiece. Tests show that the relationship between level fluctuations and the depth of slag inclusions on the surface of the casting of the workpiece is as follows: Experience has shown that surface slag inclusions can be eliminated with a level deviation within ±10 mm. In this case, when the level deviation is more than 10 mm, the proportion of longitudinal cracks on the surface of the casting blank is 30%. This means that level fluctuations directly affect the surface quality of the casting workpiece. System Principle The key to the system is the eddy current molten steel level gauge. The system works reliably and has excellent performance: high temperature resistance, strong anti-interference, fast dynamic response (lag time
