摘要:

宣钢焦化厂干熄焦装置环形风道内墙出现破损坍塌现象,分析表明,墙砖的自身缺陷、耐火泥强度的降低以及风道内长期的变温和变压环境,是造成内墙破损的主要原因。为防止内墙的整体坍塌,及时对其进行了修补砌筑并在环部严重凸起处浇筑支撑柱。修补后干熄炉总体运行良好。

Abstract:

The inner wall of the ring duct broke and collapsed in the CDQ of Xuan steel coking plant.Analysis shows that the main reasons for the collapsing of inner wall are that the brick itself has defect,strength of fire resistant mortar decreases,and temperature and pressure in the duct are not stable for a long term.To prevent overall collapsing of the inner wall,the broken places have been repaired in time.At serious crowning places concrete supports were cast.On the whole,the CDQ is in good running state after repairing.
