Heat preservation method for metallurgical converter

The invention discloses a heat preservation method, particularly discloses a heat preservation method for a metallurgical converter, and belongs to the technical field of metallurgical production equipment maintenance processes. The heat preservation method for the metallurgical converter is convenient to operate, low in operation cost and capable of effectively prolonging the service life of a lining layer of the metallurgical converter. According to the heat preservation method, waste heat of steel slag which is discharged by a steelmaking converter and has the temperature not lower than 600 DEG C is used for baking the metallurgical converter in a shutdown state, and the temperature of the metallurgical converter is always kept within a specified high temperature range. 本发明公开了一种保温方法，尤其是公开了一种用于冶金转炉的保温方法，属于冶金生产设备维修维护工艺技术领域。提供一种操作方便、运行成本低，能有效提高冶金转炉衬砌层寿命的用于冶金转炉的保温方法。所述的保温方法采用炼钢转炉排出的温度不低于600℃的钢渣的余热烘烤处于停产状态的冶金转炉，使该冶金转炉的温度始终保持在规定的较高温度范围内。
