江西萍乡钢铁厂每年产生约3万吨转炉钢渣,多年来一直未予利用,既浪费资源,又占用场地,影响环境。有时甚至因倒渣困难而影响炼钢生产。本厂钢渣中含有近60%的CaO和3%左右的MgO(CaO+MgO/SiO_2=3.95),有效CaO含量接近石灰石。另外,钢渣中还含有14%左右的铁和一定数量的锰。其物理性能特点是容重大,气孔率低。 Pingxiang Iron and Steel Plant in Jiangxi Province produces about 30,000 tons of converter slag per year, which has not been utilized for many years. It not only waste resources but also occupy the site and affect the environment. Sometimes even because of the difficulty of slag and affect the steelmaking. Our steel slag contains nearly 60% CaO and about 3% MgO (CaO + MgO / SiO_2 = 3.95), the effective CaO content close to the limestone. In addition, the slag also contains about 14% of iron and a certain amount of manganese. Its physical performance is characterized by large volume, low porosity.
