摘　　要：介绍了首秦金属材料有限公司100 t复吹转炉维护技术,通过采用控制合理的炉底厚度、调整终渣成分、优化溅渣工艺等措施,使炉龄达到8 000炉时,转炉底吹供气元件供气效果能够接近设计强度,保证了冶金效果,实现了转炉复吹与炉龄同步。The article introduces the top and bottom blowing technology of SHOUQIN 100 t converter. By controlling a reasonable thickness of the converter bottom, adjus- ting the final slag composition and optimizing the slag splashing process the campaign life of the converter reached 8 000 heats. The bottom gas supply gas of the elements are close to the designed strength. As the results the metallurgical effects are ensured and synchronization of the converter top and bottom combined blow with the furnace cam- paign is realized as well.
