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、7~12CaF2、≤5SiO2。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%。

关 键 词:KR机械搅拌法  铁水预处理  脱硫

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,7~12CaF2,≤5SiO2.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 resulfurization amount in converter melting is less than 0.002%.
Keywords:KR Mechanical Stirring Method  Hot Metal Pretreatment  Desulphurization
