对影响低气金属铬质量的主要因素进行了讨论分析。实践证明 ,通过严格控制原材料中杂质含量 ,加强冶炼和操作技术 ,铝热法生产符合电工合金要求的高质量的低气金属铬是可行的。
The main factors affecting the quality of low-chromium metal were discussed and analyzed. Practice has proved that through the strict control of raw materials in the impurity content, and strengthen the smelting and operating techniques, aluminum heat production line with the requirements of high-quality electrical alloy chromium gas is feasible.
