本研究旨在发展一种由铁水上表面逐步插入钢铠镁线的加镁新方法。将镁加入铁水是球墨铸铁生产中的一个基本工序。镁有三个主要作用:1.脱氧;2.脱硫;3.使石墨球化。然而,镁的熔点为649℃,沸点为1204℃,约在1427℃时将它加入铁水而产生较高的蒸气压,因此,对铁水球化处理过程增加困难。为使铁水与易挥发而很活泼的镁溶合在一起,并稳定获得高的镁回收率,现已发明了许
The purpose of this study is to develop a new method of magnesium addition by gradually inserting the steel wire on the surface of molten iron. Adding magnesium to hot metal is a fundamental process in ductile iron production. Magnesium has three main functions: 1. Deoxidation; 2. Desulfurization; 3. The graphite ball. Magnesium, however, has a melting point of 649 ° C and a boiling point of 1204 ° C. Adding magnesium to molten iron at about 1427 ° C produces a higher vapor pressure, thus adding difficulty to the metallization process. In order to make the molten iron and volatile volatile magnesium together, and stable access to high magnesium recovery, has been invented Xu
