Method for determining processing size of special-shaped checker bricks on periphery of heat storage chamber of hot blast stove

Abstract

The invention discloses a method for determining the processing size of special-shaped checker bricks on the periphery of a heat storage chamber of a hot blast stove. The method comprises the following steps that the inner radius R1 of a furnace shell of the heat storage chamber and the masonry design outer radius R2 of the checker bricks in the heat storage chamber are calculated according to a design drawing of the heat storage chamber of the hot blast stove; a peripheral checker brick plane two-dimensional model display model diagram is determined by combining with the size of one-body bricks and the characteristics of cross banding; a single-brick special-shaped graph formed after the special-shaped checker bricks on the periphery of the furnace body of the heat storage chamber intersect with the inner ring line of the furnace shell is determined by means of a planar array two-dimensional model graph; and according to the determined CAD1: 1 plane model of the single checker bricks one by one, a hard paperboard or a wooden splint is used for extracting an actual processing template. The method is effectively applied to the checker brick stacking project of the heat storage chamber of the Baosteel blast furnace hot blast stove, the construction period is shortened, the efficiency is improved, and the precision is improved compared with that of on-site lofting.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for determining the processing size of special-shaped checker bricks around a regenerator of a hot blast stove. Background technique [0002] The hot blast stove is a large-scale hot blast device that stores and delivers high-temperature hot blast energy for the iron ore smelting blast furnace in the ironmaking production line. Generally, the hot blast stove body is composed of three sections ( figure 1 ), the lower section is the cylindrical shell section 5 (i.e. the support area of ​​the regenerator grate in the lower section), the top is the dome area 1 of the regenerator, and the middle section is connected to the dome area 1 of the regenerator and the lower furnace shell 3 transition zone 2 from the shaft to the roof. The principle of hot air storage in the hot blast stove is that the burning hot air passes through the vertical inner holes of dozen...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages and deficiencies of the conventional technology are: 1) Occupying the site and moving a large number of bricks; 2) The processing efficiency of sample nesting is very low; 3) The processing precision of the sample is low; 4) The cost of using the sample is high;

[0005] 5) Checker brick products need to be produced and transported to the site, affecting progress
