摘要

SiMn is produced in a mechanism of smelting reduction. The properties of the slag, such as melting temperature, conductivity, fluid ability, surface tension and the ability of superheating, affects on the process greatly. Generally speaking, the slag properties depend on the addition of fluxes. The production practice indicates, however, that the slag behavior is also related to the mineralogy of the Mn ores and oepration parameters. One can not make furnace operation well merely by ajusting the basicity or the constituents of the slag. High MgO slag is acceptable for small furnaces, as a certain amount of MgO in slag improves Si reduction. The measurement of the runnign slag indicates that hearth temperature of larger furnaces is higher than that in smaller ones. The slag may often get superheated in large furnaces, which promotes the reduction process. Therefore, the slag behavior in furnaces is much more important than its chemical constitutions. In order to improve furnace operations, it is essential to balance the constituents of the slag, melting and reduction behaviors of the ores according to the furnace characteristics.
