CN107299184A 一种脱磷转炉底吹风口维护方法 无效 - 驳回

一种脱磷转炉底吹风口维护方法
摘要：
本发明涉及炼钢技术领域，尤其涉及一种脱磷转炉底吹风口维护方法，所述方法包括：向所述脱磷转炉内加入呈液态的脱碳转炉炉渣；对加入有所述脱碳转炉炉渣的所述脱磷转炉进行溅渣过程。本申请通过向脱磷转炉内添加液态的脱碳转炉炉渣，利用高碱度和高熔点的脱碳转炉炉渣进行溅渣过程，溅渣之后脱磷转炉的炉衬各部位能够形成30-50mm的溅渣层，使得增强了脱磷转炉的耐侵蚀性，并且在底吹风口部位形成渣、钢层，底吹清晰可见，保证了脱磷效果。
摘要（英）：

The invention relates to the technical field of steel-making and particularly relates to a method for servicing a bottom blowing tuyere of a dephosphorization converter. The method comprises the steps: adding liquid decarbonization converter slag into the dephosphorization converter; carrying out a slag splashing process on the decarbonization converter slag added dephosphorization converter. According to the method, through adding the liquid decarbonization converter slag into the dephosphorization converter and carrying out the slag splashing process by using the decarbonization converter slag with high alkalinity and high melting point, a slag splashing layer of 30mm to 50mm can be formed on each part of a furnace lining of the dephosphorization converter after slag splashing, and the resistance to erosion of the dephosphorization converter is enhanced; a slag and steel layer is formed at a bottom blowing tuyere part, so that the bottom blowing is clearly discernible, and the dephosphorization effect is guaranteed.
