按照常规方案更换活动烟罩,需要移开可移动段和拆除、恢复炉口固定段,工作量大,施工工期长,本文较详细的介绍了用剖分法更换活动烟罩的施工技术,而且在实践中进行了成功应用,证明是切实可行的。此方法需要拆除和恢复的设备少,可显著降低劳动强度;且施工工期短,对生产的影响较小,为同类设备的更换提供了可借鉴的经验。介绍采用剖分法更换活动烟罩的施工技术,此技术的成功实施应用,为同类设备的更换提供了可借鉴的经验。
In accordance with the conventional program to replace the movable hood, you need to remove the movable section and remove, restore the fixed section of the furnace mouth, heavy workload, long construction period, this article describes in detail the construction method of changing the movable hood with split method, and The successful application in practice proved to be practical. This method requires less equipment to be demolished and recovered, which can significantly reduce labor intensity. The short construction period and less impact on production provide the experience for the replacement of similar equipment. This paper introduces the construction technology of changing movable hood with the method of division. The successful application of this technology provides the experience for the replacement of similar equipment.
