Abstract: The effect factors on surface quality of 90 mm×90 mm electroslag continuous casting(ESCC)billet of steel Q235-0. 16C,0.25Si,0.40Mn,0.05P,0.03S have been tested and investigated. The results showed that it was favourable for surface quality of billet melted with higher voltage(53.4 V)and available current(2400 A), flux of lower melting point and lower electro-conductibility, higher filling ratio and good mold status and power supply mode.

摘要： 实验研究了成分(%)为0.16C、0.25Si、0.40Mn、0.05P、0.03S Q235钢90 mm×90 mm 电渣重熔 连铸坯表面质量的影响因素。结果表明，高电压(53.4V) 和合宜电流(2400 A)熔炼；用低熔化温度和电导率 的渣系；大填充比；良好的结晶器状况和供电方式均有利于钢坯获得良好的表面质量。
