Application of modular construction to roll hole construction of furnace wall of annealing furnace

Abstract

The invention relates to modular construction, in particular to an application of modular construction to roll hole construction of a furnace wall of an annealing furnace. The application modular construction to roll hole construction of the furnace wall of the annealing furnace comprises the steps of: 1, analyzing and optimizing a drawing, decomposing the design and installation characteristics of roll holes of the furnace wall, and drawing a part decomposition drawing of structural deployment of various roll holes; 2, off-line processing an insulating layer backer board and a masonry working layer prefabricating module in a factory, and processing the roll holes or pouring prefabricating modules according to the part drawing; and 3, calculating the modulus of the brick courses of the furnace wall on site according to level of the roll holes, setting a level from the masonry furnace wall to the roll holes, and pairing the prefabricating modules. According to the application modular construction to roll hole construction of the furnace wall of the annealing furnace provided by the invention, the masonry quality of the furnace wall can be improved and the online construction period can be shortened, and the purpose of energy conservation and emission reduction can be realized to control environmental pollution.

Description

technical field [0001] The invention relates to modular construction, in particular to the application of modular construction in the construction of an annealing furnace wall. Background technique [0002] The furnace wall of the annealing furnace is made of refractory bricks, which are usually directly constructed on site. For the furnace wall of the annealing furnace, it is very difficult to open many roller holes directly on site, and it faces the problems of poor construction accuracy and waste of a large amount of refractory materials. [0003] The on-site construction is mainly to leave roller holes manually on-line, which are prone to appear: trumpet holes, funnel holes, elliptical holes, eccentric holes, etc., resulting in the failure of the furnace roller to be installed or the gap around the roller holes is too large. If the gap around the roll hole is too large, it is easy to cause fire and air leakage during production, which will affect the stability of the fu...

AI Technical Summary

Problems solved by technology

For the furnace wall of the annealing furnace, it is necessary to open a large number of roller holes, and the direct construction on site is very difficult, facing the problems of poor construction accuracy and waste of a large amount of refractory materials.

[0003] The on-site construction mainly leaves the roller holes manually on-line, which are prone to appear: trumpet holes, funnel holes, elliptical holes, eccentric holes, etc., resulting in the failure of the furnace roller to be installed or the gap around the roller holes is too large

If the gap around the roll hole is too large, it is easy to cause fire and air leakage during production, which will affect the stability of the furnace temperature and the quality of the annealed product

[0004] On-line masonry and processing of roll hole refractory materials, there are many small pieces of special shape, and the concealed items around the roll hole are difficult to control, which affects its structure and thermal insulation performance

[0005] In order to leave qualified roller holes in conventional masonry, it is difficult to form by repeated processing and trimming of roller hole templates

There are often unqualified roll holes, which have to be discarded and reprocessed, which wastes both raw materials and labor

[0006] On-line processing and trimming of roller holes will generate a lot of waste products, which will increase the civilized construction work on site, and the generated waste products cannot be disposed of

[0007] Multiple people process in the same furnace room at the same time, resulting in large dust and great harm to the operators.
