【摘要】 在实验室用Fe-Al合金和稀土冶炼制得稀土铝铁合金,在两个工厂对新型稀土铝铁合金脱氧剂进行工业试验,转炉出钢时加稀土铝铁合金脱氧效果良好,并在钢液中有少量的稀土残留,达到同样的氧位时需要的稀土铝铁合金更少,提高了Al的收得率,降低了冶炼成本。钢液的洁净度得到提高,没有发现大型的稀土夹杂物。更多还原

【Abstract】 RE-Al-Fe alloy is made with Fe-Al alloy and Ce in laboratory.Deoxidation industrial tests are carried with a new-type alloy of RE-Al-Fe in two factories,it gets a good result,besides,less residual RE remain in the molten steel.it needs less RE-Al-Fe in the same of[O],improves the yield of Al and reduces the cost.Cleanliness of molten steel is better,large scale RE inclusion is not found.更多还原
