摘要

根据鞍钢180 t复吹转炉的实际生产情况

设计了超音速射流氧枪并进行水模型实验

避免了亚音速射流氧枪所带来的氧枪枪位修正问题。通过10:1水模型

保证最佳的底吹工艺参数不变(4孔对称

底吹流量0.70 m

/h)

改变顶吹氧枪的气体流量(38～42 m

/h)和吹炼枪位(130～210 mm)进行实验。结果表明:水模型最佳的工艺参数是枪位150 mm

流量39 m

/h。

Abstract

According to real production situation of an 180 t top and bottom combined blown converter at Anshan Steel

a supersonic jet oxygen lance has been designed to carry out water modeling test

in order to avoid the problem of revising lance position which is caused by subsonic jet oxygen lance. The test was carried out by 10:1 water model with insuring constant optimum bottom blown process parameter (4 hole symmetry

bottom blowing flowing rate 0.70 m

/h)

changing flowing rate (38~42 m

/h) and lance blowing position ( 130~210 mm) of top lance. Results showed that optimum process parameters for water model were lance position 150 mm and flowing rate 39 m

/h.
