一种转炉熔渣脱磷方法以及冶炼方法
摘要：
本发明涉及一种转炉熔渣脱磷方法以及冶炼方法。转炉熔渣脱磷方法包括如下步骤：s1，向留有熔渣的转炉内加入还原剂，并使用底部喷枪由转炉底部向转炉内吹入还原气直至完成溅渣护炉操作；s2，将喷枪降至脱磷枪位，并使用喷枪向转炉内吹入氮气和还原气的混合气，进行脱磷操作；s3，脱磷操作结束后，提升喷枪至溅渣护炉枪位，并将使用喷枪向转炉内吹入氮气，进行溅渣护炉操作。本发明该转炉熔渣脱磷方法可以实现有效提高脱磷率和脱磷效率。
摘要（英）：

The invention relates to a converter slag dephosphorization and smelting method. The converter slag dephosphorization method comprises the following steps: 1, adding a reducing agent into a converterwith slag, and blowing reducing gas into the converter from the bottom of the converter by using a bottom spray gun until the slag-splashing for protection of converter operation is completed; 2, lowering the spray gun to a dephosphorization gun position, and blowing mixed gas of nitrogen and the reducing gas into the converter by using the spray gun to perform dephosphorization operation; and 3,after the dephosphorization operation is finished, lifting the spray gun to a slag-splashing for protection of converter gun position, and blowing the nitrogen into the converter by using the spray gun to perform the slag-splashing for protection of converter operation. According to the converter slag dephosphorization method, the dephosphorization rate and the dephosphorization efficiency can beeffectively improved.
