在实验室25kg顶底复合吹转炉上进行了中磷铁水(0.5—1.0％[P])脱磷试验。以块状石灰和铣皮为造渣剂,釆用双渣不留渣法操作,研究了冶炼中炉渣成分及温度对脱磷的影响,并提出了合适的炉渣成分及温度控制。
In the laboratory 25kg top and bottom composite blown on the phosphorus in the molten iron (0.5-1.0% [P]) dephosphorization test. Using massive lime and milling as slagging agent, the operation of double slag without residue was adopted to study the effect of slag composition and temperature on dephosphorization in smelting, and the suitable slag composition and temperature control were proposed.
