摘　　要：为满足市场对低硅金属铬的需求,针对金属铬生产的特点,增加了铬酸钠中和工序,更换了氢氧化铬煅烧窑窑衬材质,使金属铬中杂质硅的质量分数有了大幅度的降低,满足了市场的需求。To meet market demand on low silicon metallic chromium, combined with its production characteristics, taking measures of increasing the process of neutralization for sodium chromate and changing the calcined kiln lining of chromium hydroxide, which dramatically reduce mass fraction of impurity silicon from metallic chromium.

关 键 词：金属铬 硅 中和 窑衬
