介绍了马钢炼焦生产存在的环保问题。分别通过1＃～4＃焦炉筛焦及干熄焦除尘优化，7．63m焦炉推焦除尘技术改进，以及5＃～6＃焦炉装煤、出焦等3套除尘地面站建设，使粉尘得到收集。此外，加强老龄化焦炉维护管理、使用新型涂釉耐火材料、改进刀边等措施，抑制了焦炉非阵发性烟尘的跑冒。%Environmental problems during coking production of Masteel coke oven battery are described.Dust is collected through the methods of coke screening for battery No.1~4, optimizing CDQ de-dusting, technical improvement on pushing de-dusting of 7.63m coke oven battery, and construction of 3 stationary bag house stations for charging and pushing of battery No.5~6.In addition,measures such as strengthening the maintenance and management of aged ovens,using new glazed refractory and improvement on knife edge can effectively minimize the leakage of intermittent smoke.
