采用钢水炉外处理法的主要目的,一是降低钢水硫含量,二是改变非金属夹杂的性质。意大利冶金中心(CSM)研究出两种钢水处理新技术:包芯线喂入法和铁盒压入法。添加包芯线的主要目的是改变夹杂。浇铸时,把内含低Ca或低Mg、碱土金属合金的包芯线(φ10毫米》,以螺线形喂入中间包内,喂入量随中间包内钢水深度和温度的变化而增减。铁盒压入的主要目的是获得低硫钢水、改变非金属夹杂及获得良好的钢水流动性。该法是把富集的Ca、Mg添加料装进一个特
The main purpose of using molten steel furnace treatment method, one is to reduce the sulfur content of molten steel, the second is to change the nature of non-metallic inclusions. The Italian Metallurgical Center (CSM) has developed two new technologies for the treatment of molten steel: cored wire feeding and tin insertion. The main purpose of adding cored wire is to change inclusions. Casting, the inclusion of low Ca or low Mg, alkaline earth metal alloy cored wire (φ10 mm ") fed into the tundish, the amount of feed with the tundish depth and temperature changes in the increase and decrease. The main purpose of the iron box into the low-sulfur molten steel to change, change the non-metallic inclusions and access to a good flow of molten steel.This method is to enrich the Ca, Mg additives into a special
