一种转炉真空炼钢的方法
摘要：
本发明涉及一种转炉真空炼钢的方法，所述方法包括以下步骤：转炉前倾15～20°，进行兑铁；转炉前倾20～30°加入废钢；转炉摇至吹炼位置，开启抽真空装置，转炉内部钢液上方的压力降为1.33×10-1～133.3Pa；吹氧冶炼；关闭抽真空装置后，进行取样与测温；倒炉出料。该方法可有效的去除钢水中氮、氢、氧等气体含量，促进脱碳脱氧反应的进行，减少金属及非金属夹杂，提高钢水纯净度，提升产品质量。
摘要（英）：

The invention relates to a converter vacuum steelmaking method comprising the steps that: the converter is leaned forward by 15-20 DEG, and iron blending is carried out; the converter is leaned forward by 20-30 DEG, and scrap steel is added; the converter is swung to a blowing position; a vacuuming device is started; the pressure above molten steel in the converter is reduced to 1.33*10<-1> Pa to 133.3Pa; oxygen blowing and smelting are carried out; the vacuuming device is turned off, and sampling and temperature measuring are carried out; and furnace turning and discharging are carried out. With the method, contents of gases such as nitrogen, hydrogen, oxygen, and the like in molten steel can be effectively removed, such that decarbonization and deoxidation reactions can be promoted, metal and non-metal impurities can be reduced, molten steel purity can be improved, and product quality can be improved.
