摘要
以100 t顶底复吹转炉与氧枪工艺参数为基础,采用冷态模拟方法,研究了熔池深度、枪位、顶吹和底吹气体流量对转炉冶炼效果的影响规律.结果表明,100 t顶底复吹转炉的熔池深度控制在1.25 m以内,有利于延长炉底的使用寿命;枪位控制在60～90 mm（实际枪位为1.25～1.5 m）范围内、顶吹流量为37 Nm3/h（实际流量为21 000 Nm3/h）时,能提高搅拌强度,保证适当的熔池冲击深度以及最小的炉口喷溅量.
With process parameters of 100 t top and bottom combined blown converter and oxygen lane asbase and cold state simulation method, it is researched the influence law of bath depth, lane location and topand bottom blown gas flow rate on smelting effect of converter. It is showed from the result that the bathdepth should be controlled within 1.25 m to be favor to prolong the work life of bottom ; lane location controlrange being 60 to 90 mm （ actual value as 1.25 to 1.5 m）, top blown flow rate 37 Nm3/h （ actual value as21 000 Nm3/h）, and so the stirring strength can be raised to guarantee a suitable bath impact depth and smal-lest mouth spitting amount.
