Application No. 87101576.5 Date of Application 1987.6.24 Applicant Benxi City Metal Material Factory Address Gaoyu Street, Mingshan District, Benxi City, Liaoning Province The composite deoxidizer of the present invention is composed of Al-FeSi-Fe and is suitable for deoxidation in steelmaking, especially Suitable for ordinary killed silicon content ≥ 0.3 ordinary steel and silicon content of low alloy steel smelting process of deoxygenation. The disadvantages of the existing steel-making aluminum-iron deoxidizer or pure-aluminum deoxidizer are: severe pulverization of aluminum and iron and unreasonable metal structure. There is a small proportion of pure aluminum deoxidizer, easy to float on the surface of the molten steel caused serious damage, aluminum consumption
