宝钢焦炉推焦车外轨在线改造技术实践

介绍宝钢焦炉推焦车外轨首次在线进行固定型式改造的技术应用实践，主要包括改造工艺介绍、改造难点分析以及所采取的具体改造技术措施。因推焦车外轨改造是在焦炉保持正常生产状态条件下进行，在施工过程中采取了针对性技术措施，克服了工艺交叉、施工环境复杂、安全等多方面困难，提高了施工效率，极大缩短了工期，减少了对焦炉生产的影响。同时，还提出了相关改进建议，可供其他类似机车轨道在线改造参考。

Practice of online transformation technology of coke pusher outside track of coke oven in Baosteel

The first online fixed transformation technology of the coke pusher outside track of coke oven in Baosteel was introduced, which mainly included the introduction of the transformation process, the analysis of the difficulties of the transformation, and the specific technical measures taken. The transformation of the outside track of the coke pusher was conducted on the condition of the normal production of the coke oven. And the specific technical measures were taken during the construction process, which overcame the difficulties of the process crossing, the complex construction environment and the safety. The construction efficiency was improved, the time limit was greatly shortened, and the effect on the production of coke oven was reduced. At the same time, the relevant suggestions for other similar locomotive rail online transformations were put forward.
