Embodiment Construction

[0012] Example figure 1 As shown, the annealing furnace shell modular installation method of the present invention comprises the following steps:

[0013] Step 1. Set up a steel structure platform 1 for supporting the furnace shell of the annealing furnace, and mark the positioning line 2 of the bottom plate of the furnace shell and the reference line 3 of the wall plate of the furnace shell on the installation position of the furnace shell on the top surface of the steel structure platform 1;

[0014] Step 2, modularize the annealing furnace shell, including a number of furnace shell bottom plate modules 4 and furnace shell wall plate modules 5 connected in sequence and mark the installation serial number;

[0015] Step 3. Hoist the furnace shell bottom plate module 4 of the previous serial number to the steel structure platform 1 and adjust the positioning according to the positioning line 2, hoist the furnace shell wall plate module 5 corresponding to the furnace shell bott...

Abstract

The invention discloses an annealing furnace shell modular installation method. The method comprises the following steps that firstly, a steel structure platform used for supporting an annealing furnace shell is erected, and a furnace shell bottom plate positioning line and a furnace shell wallboard reference line are marked; the annealing furnace shell which comprises several sequentially-connected furnace shell bottom plate modules and furnace shell wallboard modules is manufactured in a modular mode, and installation serial numbers are marked; the furnace shell bottom plate modules are hoisted to the steel structure platform in sequence and are adjusted and positioned according to the positioning line, the furnace shell wallboard modules corresponding to the furnace shell bottom plate modules are hoisted to the steel structure platform and are adjusted and positioned according to the reference line, the furnace shell bottom plate modules and the furnace shell wallboard modules are assembled through welding until welding assembling of all the furnace shell bottom plate modules and furnace shell wallboard modules is completed. According to the method, the defects of a traditionalsingle-piece installing mode of the annealing furnace shell are overcome, the assembling period is effectively shortened, and the assembling efficiency is improved, the size precision and quality of the installation of the furnace shell are ensured, and the subsequent installation operation of equipment in the furnace shell is facilitated.

Description

technical field [0001] The invention relates to a modular installation method for an annealing furnace shell. Background technique [0002] With the development of the metallurgical industry, the construction technology of cold rolling engineering is also constantly developing and improving. The installation of annealing furnace shell occupies a very important position in the construction process of cold rolling engineering. Generally, the annealing furnace shell is supplied in pieces and assembled on site. The assembly and welding workload of the annealing furnace shell is large, and due to the limitation of the site, the assembly period is long, the efficiency is low, and it is difficult to ensure the size Accuracy requirements have a great impact on subsequent equipment installation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modular installation method for an annealing furnace shell. This method overc...
