These natural minerals with low melting point, accelerate the dissolution of lime, and form a slag of high basicity and good fluidity suitable for desulphurization.

这些天然复合矿物具有较低的熔点并且能满足流动性好的高碱度炉渣的去硫作用。

Industrial scale experimental results demonstrate that the slag smelted in this way can protect the ladle lining against penetration corrosion for it is of low smelting point and of sound fluidity.

工业试验结果表明，优化后的精炼渣系熔点低、流动性好，冶金效果显著，对包衬有明显保护作用。
