By analysing the flow sheet of producing low/simplex carbon ferrochrome with silicothermic method,we find out the main factors and mechanism which affect production index. 分析了电硅热法生产低微碳铬铁的工艺流程,找到了影响生产指标的主要因素及作用机理。
Abstract: The Gibbs free energy and critical reduction temperature of vacuum silicothermic reduction producing metallic strontium were calculated and analyzed by thermodynamics. 摘 要: 采用热力学方法计算并分析真空硅热法炼锶的反应自由能和临界还原温度。
Through the experiment of vacuum silicothermic reduction producing metallic strontium, the pure metallic Sr (98.53%, mass fraction) is obtained and the metal yield is 55%. 通过真空硅热法炼锶实验获得纯度(质量分数)为98.;53%25的金属锶,锶的收得率为55%25。
It points out that it is obvious that the recovery rate of metal magnesium influences consuming data.Therefore,an effective approach is found out of making magnesium with silicothermic method. 计算结果指出:金属镁回收率对各项消耗指标的影响是显而易见的。
