Abstract
In order to apply the technology of slag splashing into a nickel smelting converter, the thermal simulation of slag splashing in a nickel converter was carried out with a Mg-Cr crucible in the laboratory. The results show that the FeO-Fe2O3-SiO2-MgO system is a reasonable slag type for slag splashing, increasing the contents of MgO and Fe2O3 in the slag can remarkably raise the moltentemperature, and accordingly, such high melting phases as ferrohortonolite and magnetite increase dramatically. The slag splashing layer with high melting temperature can be formed by means of such a kind of slag. The inner surface of the crucible includes a reaction layer and a slag sticking layer. Phases in the reaction zone are Mg-Fe solid solution and Mg-Cr-Fe-A1 spinal, while phases in the slag sticking layer are ferrohortonolite and magnetite. The Fe2O3 content can be increased by air injection, which is an ideal gas for slag splashing.关键词
