江苏江都合金厂经过多次试验,研制并熔炼成功一种新型脱氧剂——铝铁合金。该脱氧剂含铝量为52％,比重5.5,大于钢渣比重,其熔点为1180℃,高于钝铝熔点,可直接穿过钢渣层与钢水结合,不会引起钢液降温,由于它化学成份均匀,无偏析,脱氧效果十分理想。经马鞍山、沈阳、哈尔滨、南京等许多钢厂使用表明,脱氧稳定可靠,铝的利用率高,
Jiangsu Jiangdu alloy plant after several tests, the successful development and smelting a new type of deoxidizer - aluminum-iron alloy. The deoxidizer containing 52% of aluminum, the proportion of 5.5, greater than the specific gravity of steel slag, the melting point of 1180 ℃, higher than the melting point of blunt aluminum, steel slag can be directly through the layer and the combination of water will not cause molten steel cooling due to its chemical composition Uniform, no segregation, deoxidation effect is very good. The use of many mills in Ma’anshan, Shenyang, Harbin and Nanjing shows that the deoxidation is stable and reliable, the utilization rate of aluminum is high,
