摘要
介绍了唐山国丰钢铁公司炼钢脱氧新材料钢砂铝的生产工艺及理化指标。从实际脱氧效果、铸坯氧氮含量、成本等方面与原脱氧用材料铝铁进行了对比。结果表明,每千克钢砂铝较铝铁多脱氧1.42ppm,成本低1.65元/t钢,对铸坯氧氮含量无明显影响,对钢水成分的影响可忽略不计。
It is introduced the production process and physical and chemical indexes of steel aluminum,a new deoxidation material for steel making. It is compared with the original ferro- aluminum in actual deoxidation effect,oxygen and nitrogen contents in casting billet and cost： in the first item,the former is 1. 42 ppm /kg higher than the latter; in the cost,the former 1. 65 yuan /t lower than the latter; the former has no obvious influence on the second item,little effect on molten steel composition.
