Continuous Casting Mold Level Control System

概述 结晶器钢水液位自动控制是连铸生产的关键技术之一,对减轻工人劳动强度,提高生产效率,提高铸坯质量和产量,减少溢钢、漏钢,提高炼钢连铸管理水平具有十分重要的意义。 钢水倒入结晶器内,为防止溢流,必须保持钢水液面稳定,否则在浇铸过程中,如果液面波动过大,就会卷入炉渣,在铸坯表面形成表面夹渣,影响铸坯质量。试验指出,液面波动与铸坯表面夹渣深度的关系如下: 经验表明,当液位波动在±10mm以内时,可以消除铸坯表面夹渣,同时,当液位波动大于10mm时,铸坯表面纵向裂纹的产生率达30%,即液位波动直接影响铸坯表面质量。       系统原理 The eddy current type molten steel level gauge is the key to the system. The system operates reliably and has excellent performance: high temperature resistance, strong anti-interference ability, fast dynamic response (lag time <0.10s), high detection accuracy (<±05mm), and large measurement range (0-150mm). The selected electromagnetic field frequency ensures that the
