Embodiment Construction

[0036] The plug-in method for installing a converter provided by the present invention is a method for installing a converter body in cooperation with a hoist and a hoist. Body adjustment and support device installation. Specifically, follow the steps below:

[0037] Step 1. Winch and lifting point setting:

[0038] 1. Set up two 10t winches on the third floor platform of the plant structure, and fix them close to the plant columns. The first 10t single pulley is set on the third floor platform on the converter foundation, and the second 10t single pulley is set on the girder of the fourth floor platform, arranged on both sides of the converter foundation, next to the fixed pulley block. Set up two 10t winches on the fourth floor platform, set up a beam at the hole where the flue is installed on the fifth floor, and fix it by welding. Set up two lifting points on the beam, which are arranged on both sides of the center of the converter.

[0039] 2. Set up two lifting points...

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 ...
