摘要：

由于干熄焦生产不稳定，造成炉体耐火材料龟裂、剥落、破损严重，需要对干熄炉本体冷却段、“牛腿”、环梁、环形风道内环、炉口及一次除尘器侧墙、高温膨胀节等部位进行维修，以满足正常生产需要。采用传统的砌筑技术砌筑工期长、新旧墙接茬部位膨胀不一致，强度差，采用耐火材料浇筑砌筑技术修复后，新旧墙接茬部位膨胀一致，砌体强度高。

Abstract:

In the event of unstable CDQ operation,it would cause serious damages to the CDQ chamber refractory,like cracks and flake-offs,which needs a series of repairs,such as on the cooling section of the CDQ proper,bracket,ring beam,inner ring duct,chamber mouth,side wall of the primary deduster and high temperature expansion joint,etc.to meet the requirement for normal production.Since the conventional bricklaying takes longer time,there would be differential expansion between the existing wall and the newly-built,and the joint in between has poor strength.Therefore the new casting technology can repair the joint between the existing wall and the new wall with consistent expansion and with high strength of the brickwork in one piece.

Key words: CDQ chamber, Refractory material, Casting
