Method for installing converter in plug-in mode

Abstract

The invention relates to a method for installing a converter in a plug-in mode, in particular to a method for installing a converter body by matching a travelling crane with a hoist. The method comprises the following steps of: arranging the hoist and a hoisting point; installing a bearing base; hoisting a backing ring; installing a tilting mechanism; hoisting the converter body; regulating the converter body; and installing a supporting device. The invention does not need to demolish a finished plant structure, use a complex hoisting machine and increase the construction investment, reduces the operating cost of special machines and tools and the costs of materials, manufacture, installation, and the like of supporting devices, slideways and hoisting tools, thereby saving the cost; and in addition, the invention has short practical hoisting time and high operability, is suitable for improving and increasing the converter inside an old plant and is especially suitable for implement when the traditional integral installation method can not be used for construction due to a narrow construction field when the construction of the plant structure is finished or an old converter is improved without influencing the production of an owner.

Description

technical field [0001] The invention relates to a converter installation method, in particular to a plug-in converter installation method for adding and transforming a medium-sized converter in an old factory building. Background technique [0002] The traditional installation method of the converter is to make a carrier frame, use the ladle car to haul it as a whole, or set up a slideway to move it as a whole. However, it is necessary to design the form of the bench and the slideway and use a large amount of materials to make the bench, which needs to be hauled by a ladle truck and the overall movement of the slideway. The production time is long and it needs to be dismantled after completion; The platform and surrounding structures have been constructed, so the traditional method cannot be used. If the traditional method is to be used, a large number of platforms and columns need to be dismantled. In addition, the restoration after the event requires a lot of manpower and ...

However, it is necessary to design the form of the bench and the slideway and use a large amount of materials to make the bench, which needs to be hauled by a ladle truck and the overall movement of the slideway. The production time is long and it needs to be dismantled after completion; The platform and surrounding structures have been constructed, so the traditional method cannot be used. If the traditional method is to be used, a large number of platforms and columns need to be dismantled. In addition, the restoration after the event requires a lot of manpower and material resources

The traditional method of moving the slideway as a whole and dragging the ladle car as a whole needs to be implemented after the furnace shell and support ring are assembled, which takes a long time to prepare
