摘　　要：为满足品种钢开发要求,降低耐材消耗,济钢采用了无碳新技术钢包,即采用无碳预制件砌筑包壁,包底整体浇注打结,运行过程中进行4～6次喷补小修。新技术喷补料修砌喷补后,在高温下与包壁预制件变质层的矿物相进行互相渗透、互相反应,生成具有优良性能的反应层,从而把使用过的变质层与新喷补层牢固地粘接在一起,形成的衬体达到与原有预制件相同的使用效果,抗侵蚀耐冲刷,平均寿命达到175炉以上。In order to meet the needs of new steel variety development and to reduce the refractory consumption,Jinan Steel adopted carbon free new technology ladle,that is,building the ladle wall by carbon free precast block,casting and ramming the ladle bottom entirely and making spray repair from four to six times in whole serving life.After spray repair,the new technology gunning refractory reacted and penetrated with the mineral phase of the ladle wall precast block affected layer each other,forming reaction layer with excellent properties that joined the affected layer and the gunning layer.The new lining with the same cycle time with the precast block was corrosion resistance and superior resistant to molten steel.The average serving life of the ladle reached 175 heats above.
