钢包包型的研究与应用

Study and application of ladle shape for liquid steel

通过对钢包耐材消耗、钢结构重量、投资、钢包散热、运行成本、冶金效果等多个方面,对比了两种80 t钢包的优缺点,论述了80 t钢包在包内钢水熔池直径与熔池深度的比值接近1时,具有如下优势:1)钢包设备重量轻,设备投资可节省(52~62.4)万元;2)耐材消耗低,年可节省6.8万元;3)运行成本低,年可节省25万元;4)钢包散热少,能耗低,年可节省42.1万元;5)可以减少钢水的死区,有利于除去夹杂物;6)可减少涡流卷渣,提高钢水的纯净度。

In this paper,the advantages and disadvantages of two kinds of 80 t steel ladle were compared from the aspects of refractory consumption,steel structure weight,equipment investment,ladle heat dissipation,operation cost and metallurgical effect.When the ratio of diameter to height of liquid steel bath in the 80 t steel ladle is close to 1,it has the advantages,1)Ladle has a lower weight and equipment investment is saved by $520000~624000;2)The refractory are consumed less and cost is saved by $68000 every year;3)Operation cost is lower and saved by $250000 every year;4)Ladle heat dissipation is less and cost is saved by $421000 every year;5)Blind spots are reduced and is better for inclusion floating;6)The slag drawn into by vortex is reduced and the purity of liquid steel is heightened.
