Embodiment Construction

[0016] The present invention is further illustrated below by specific examples.

[0017] figure 1 The rapid assembly method of the enlarged furnace shell and lining structure of the top-fired hot blast stove shown includes:

[0018] Step 1. Assemble and weld the furnace shell at the lower straight section of the S-curve on the assembly platform, and level the upper part of the entire furnace shell, retest and correct the ellipticity;

[0019] Step 2. Based on the center of the straight furnace shell, draw the diameter projection of the upper opening of the S-curved enlarged belt on the ground of the assembly platform, and assemble the furnace shell with the S-curved enlarged belt on the upper part of the straight furnace shell;

[0020] Step 3. The installation position of the vertical rib plate of the supporting brick plate is positioned on the inner wall of the furnace shell with S-bend expansion belt;

[0021] Step 4. Groove the liner and hoist it in pieces according to t...

Abstract

The invention relates to the field of construction of dome-combustion hot stoves and particularly relates to a rapid assembling method for an enlarged zone stove shell and a lining structure of a dome-combustion hot stove. The method is characterized by comprising the following steps: S-bend lower-part straight-section stove shell assembling, S-bend enlarged zone stove shell assembling, tile bearing plate-stud plate locating paying-off, inner container slotting, inner container hoisted-to-S-bend-interior assembling, tile bearing plate-stud plate upper-half welding, S-bend and straight-sectionstove shell jacking, tile bearing plate-stud plate rest lower-half welding and tile bearing plate mounting. According to the rapid assembling method, the problem during the assembly of an S-bend enlarged zone stove shell of the dome-combustion hot stove that the requirements on site space are high is effectively solved, meanwhile, secondary hoisting transportation can also be reduced, then, the assembling speed is accelerated, the approach time of large hoists is retarded, the machine shift of cranes is reduced, and the efficiency of construction is increased.

Description

technical field [0001] The invention relates to the construction field of a top-combustion hot blast stove, in particular to a rapid assembly method for an enlarged belt furnace shell and an inner lining structure of a top-combustion hot blast stove. Background technique [0002] At present, most domestic hot blast stoves use top-fired hot blast stoves. This type of stove can meet the requirements of high temperature, high pressure and large-scale development of blast furnaces, and its combustion capacity is significantly improved compared with previous external combustion hot blast stoves. However, the disadvantage is that the height of the casing is high, and there are many variable diameter belts, especially the S-bend expansion belt of the burner section. In order to avoid high-altitude operations, it needs to be assembled on the ground and the inner lining as a whole for hoisting. Moreover, most of the lining accessories in this part are load-bearing structures, the fur...
