Smelting method of phosphorus containing steel

The invention discloses a phosphor containing steel smelting method. Converter is adopted fast heating up to eliminate carbon, save phosphor, and make high phosphor slag smelting operation. When the converter is at blowing early stage, oxygen lance positing is between 0.0-1.0meter, diacidic base degree is 1.0-2.5, oxygen supply intensity is 2.8-5.0m3/t. min, 0.5-45.0kg/ton steel barringerite or phosphate ore is added into the converter; then 1.0-30.0kg/ton is added at the blowing late stage. After scrap steel is melted with iron liquid to form molten steel in electric furnace, slag forming material is add, diacidic base degree is 1.0-2.5, oxygen supply intensity is 1.5-4.5m3/t.min. 0.5-40.0kg/ton steel barringerite or phosphate ore is added into molten steel at decarbonizing process; and 0.5-30.0kg/ton is added at smelting late stage. This smelting method can make most phosphor enter molted steel to do phosphor alloying.
