【摘要】 本文根据某厂1450连铸机设计出了新型旋流水口,并采用水模型研究方法,研究了使用旋流水口时结晶器液面卷渣情况、流股冲击深度、液面波动和流体流场。研究结果表明:使用旋流水口可提高拉速:在相同条件下可降低流股冲击深度,减少液面波动幅度。更多还原

【Abstract】 The swiding SEN was designed according to 1450 continuous casting caster used in a steelmaking plant.Water simulation experiment was adopted in this paper.The liquid level slag inclusion, fluctuation condition,flow field and impact depth were investigated on the condition of using the swirling SEN.The results indicated that applying swirling SEN could increase pulling rate and reduce impact depth but decrease liquid level fluctuation under identical conditions.更多还原
