摘　　要：圆坯连铸机液面控制系统,能实现结晶器钢水液面自动浇注,减少浇钢工的劳动强度,实现钢水液面平稳运行,杜绝因钢水结壳造成拉漏事故发生,能改善铸坯表面质量,确保产品质量达到预定要求;相对于手动浇注时,由于液面波动大,夹渣、卷渣、拉速变化快而引起冷却不均匀,影响了铸坯的表面质量及铸坯产生内部缺陷。钢水液面自动控制系统的优点是液面稳定,拉速波动小,克服了手动浇注的缺点,从而提高了铸坯质量。The liquid level casting control system of the round billet continuous casting machine can achieve automatic pouring of the molten steel level in the mold,reduce the labor intensity of the pouring workers,achieve stable liquid steel level,prevent the occurrence of tensile accidents caused by molten steel crusting,improve the surface quality of the casting billet,and ensure that the product quality meets the predetermined requirements.Compared to manual pouring,uneven cooling is caused by large fluctuations in liquid level,slag inclusion,slag curling,and rapid changes in casting speed,which affects the surface quality of the billet and internal defects of the billet.The automatic liquid level control system brings stability to the liquid level and small fluctuation in casting speed,overcoming the shortcomings of manual pouring and improving the quality of the casting billet.
