摘　　要：分析了马钢焦化新区两座7.63 m焦炉炉门结构改造前出现的问题:炉门跑烟跑火严重,机侧砖槽烧损严重,炉门更换频次高、修理工作量大及焦侧严重塌焦等;采取了相应改进措施:将原设计的"Z"型刀边改为腹板式刀边、将焦侧炉门衬砖和机侧小炉门砖槽分别进行改型等。通过优化改型,取得了预期效果,减轻了工作强度,产生了较好的经济效益和社会效益。The problems of doors of 2 ×7.6 3 m coke ovens in Maanshan Iron Steel Coal-coking Company before the structural modification were analyzed： the coke oven door had serious smoke and flame run-out,the burning loss of the pusher side brick slot was serious,the replacement frequency of coke oven door was high,the repair workload was heavy,and the coke side collapsed seriously. Corresponding measures were taken by changing the originally designed ＂Z＂ type knife edge into web type knife edge,and modifying the lining brick of coke oven door in the coke side and brick slot of small coke oven door in the pusher side. The work intensity was reduced through optimization and modification,achieving good social and economic benefits.
