分析得出武钢7.63 m焦炉部分焦炭偏生及废气盘处煤气泄漏等问题是因蓄热室格子砖变形熔损引起;接着对7.63 m焦炉71A～72三个蓄热室格子砖更换的准备工作、更换过程及更换后燃烧室的升温和恢复生产进行了介绍;最后得出,蓄热室格子砖变形熔损主要是由于7.63 m焦炉蓄热室的分格式设计、开工初期石墨问题及加热煤气和格子砖材质所引起;武钢7.63 m焦炉蓄热室格子砖更换恢复生产后横排曲线正常且废气盘处无煤气泄漏情况,焦炉顺产的同时也减轻了企业安全环保压力,给国内同行提供了借鉴.
The current study analyzed the reasons of the incomplete maturity of partial coke and the gas leakage at the exhaust disk in WISCO 7.63 m coke oven. It's inferred that was caused by checker brick deformation and jam of regen-erator. Then the preparation of the replacement,the replacement,the replacement steps,the temperature rise and recov-ery of the checker brick of 71A-72 on 7.63 m coke oven were introduced. The checking of the checker brick showed that the main reasons of the problem were the design of the checker brick of the regenerator,graphite problems at the initial stage and the heating gas and the material of the checker brick. The horizontal curve became normal and there was no gas leak after the checker brick of regenerator was replaced in WISCO 7.63 m coke oven. Meanwhile,the improvement of the smooth operation of coke oven relieved the pressure of safety and environmental protection which provided some references for the domestic counterparts.
