摘要

通过KR机械搅拌法和喷吹法各自优势的比较

选用了KR法对205 t铁水进行脱硫预处理。所使用的脱硫剂的主要成分为(%):76～80CaO、7～12CaF

、≤5SiO

。生产结果表明

经KR搅拌法预处理后

铁水中硫含量可降至0.005%以下

搅拌头使用寿命可达270炉;经KR法预处理铁水总时间为35～42min;转炉冶炼时回硫量不高于0.002%。

Abstract

The KR method is selected for pretreated desulphurization of 205 t hot metal according to the comparison results of advantages and characteristics between KR mechanical stirring method and jetting method. The main ingredient of used desulphurizing agent is (%) 76 ~80CaO

7 〜12CaF

≤5SiO

. Production results show that after pretreatment by KR stirring method

the sulfur content in hot metal may decrease to less than 0. 005% ； the service life of stirring head is 270 heats; the total pretreated time by KR method is 35 - 42 min ； and the desulfurization amount in converter melting is less than 0. 002%.
