涟源钢铁厂为了解决高磷赤铁矿入炉的问题,委托武汉钢铁学院炼铁教研室就该厂条件铁水炉外同时脱磷、脱硫降低生铁磷、硫含量进行可行性研究。研究工作应达到的目标是:①如果未来涟钢生铁含磷为0.7～0.8%,含硫为0.09%,经处理后脱磷率稳定地达75～80%,[P]≤0.18%;脱硫率稳 Lianyuan Iron and Steel Plant in order to solve the problem of high-phosphorus hematite into the furnace, commissioned by the Iron and Steel Institute of Wuhan Iron and Steel Institute of the same conditions outside the furnace hot metal dephosphorization, desulfurization to reduce pig iron phosphorus, sulfur content feasibility study. The objectives to be achieved by the research work are as follows: ① If the phosphorus content of the pig iron in the future is 0.7-0.8% and the sulfur content is 0.09%, the treated dephosphorization rate will reach 75-80% steadily, [P] ≤0.18%; desulfurization Stable
