摘要/Abstract

摘要： 介绍了钢包中钢液钙处理的起源及钙的加入方法和研制的气体旋流喂丝枪和高致密椭圆截面包芯线。建议包芯线成形机和喂丝机生产企业借鉴焊管成形机进行技术改造,生产椭圆截面包芯线成形机;将圆拄面齿形喂丝轮改造成圆弧槽喂丝轮;钢铁企业喂丝处理时增加活动导丝管升程,以实现钢液内部喂丝钙处理。

关键词: 钙处理, 喂丝机, 喂丝枪, 包芯线, 椭圆截面

Abstract: The origin of calcium treatment of molten steel in ladle and adding calcium method as well as developed gas rotary feeding wire lance and high-density cored-wire with elliptic section are presented in this article. It is suggested that using the experience of welded pipe forming machine the technical revamp of cored-wire machine shall be carried out at cored-wire forming enterprises and machine manufacture enterprises to produce elliptic cored-wire forming machine and change the cylinder face gear for feeding wire to the arc tough gear for feeding wire； and at steel works the stroke of mobile guide tube in feeding process should be increased to achieve the feeding wire calcium treatment in molten steel.

Key words: Calcium Treatment, Wire Feeder, Wire-Feeding Lance, Cored-Wire, Elliptic Section
