利用固体碳和碳饱和的锰熔体做还原介质研究了MnO和SiO2从熔融的〔SiO2-MnO-CaQ〕和〔SiO2-MnO-CaO-Al2O3〕渣中还原的速率.温度的范围从1500℃到160Q℃,一氧化碳气体的气氛为大气压.用高温天平监测反应中的重量损失。发现碱性渣还原分成两个阶段,并且这二个阶段都受化学反应的控制:第一阶段受MnO还原的控制,缓慢的第二阶段受SiO2还原的控制.当酸性渣还原时,则没有第一阶段.所研究的试验变量中有渣和合金的成分、反应温度、搅拌比和熔体的几何尺寸等.
The reduction rates of MnO and SiO2 from molten [SiO2-MnO-CaQ] and [SiO2-MnO-CaO-Al2O3] slag were investigated using a solid carbon and a carbon-saturated manganese melt as a reduction medium. The temperature ranges from 1500 ° C to 160 ° C and the atmosphere of carbon monoxide gas is atmospheric pressure. Monitor the weight loss in the reaction with a high temperature balance. It was found that the alkaline slag reduction is divided into two stages, and both of these stages are controlled by the chemical reaction: the first stage is controlled by MnO reduction and the second, slow stage is controlled by the SiO2 reduction. When the acid residue is reduced, there is no first stage. The experimental variables studied include the composition of the slag and the alloy, the reaction temperature, the mixing ratio, the melt geometry, and the like.
