一、引言钢渣是一种物相复杂的工业废渣。各种研究表明,钢渣可生产人造石和钢渣水泥等建筑材料。钢渣中的物相,有的对生产建筑材料有利,有的则有害,其化学成分特别是物相含量直接关系到钢渣能否被利用,钢渣中物相的种类及含量常有较大的波动,给钢渣的有效利用带来一定困难。因此,确定钢渣中物相的含量乃是合理利用钢 First, the introduction of slag is a phase complex industrial waste. Various studies have shown that steel slag can produce building materials such as artificial stone and steel slag cement. Some of the steel slag in the phase, some for the production of building materials, while others are harmful, its chemical composition, especially the phase content is directly related to the availability of steel slag, steel slag species and content often have large fluctuations , To the effective use of steel slag brought some difficulties. Therefore, to determine the content of steel slag phase is the rational use of steel
