Embodiment Construction

[0019] figure 1 In the process, several slabs (1) as liners lean against the embedded iron plate (10) of the hot stuffy pool wall (6) at a certain angle, and utilize their own weight to stabilize the structure. The bottom of the slab (1) leaves a distance of about 250 millimeters from the hot stuffy pool wall (6), utilizes the steel plate (5) at the bottom of the pool, and welds the iron (7) close to the outer side of the slab (1), and each slab ( 1) There are two or more welding rails (7), so that the billet (1) cannot be close to the pool wall (6) even when it is subjected to a relatively large impact force. The wedge iron (4) on the inner side of the slab (1), each Two or more pieces of slab (1) welding wedge iron (4) make the slab (1) not topple over to the center of the pool. In this way, an inner wedge and an outer stop are formed at the lower part of the slab (1), so as to control the degree of freedom of the slab without affecting its degree of expansion and contracti...

Abstract

The invention relates to a method for installing and fixing a large lining plate for a metallurgical steel slag treatment hot stuffy tank. The method is characterized in that: plate blanks serving as lining plates lean against an embedded iron plate on the wall of the hot stuffy tank in certain angles and play a role in structure stabilization by using dead weight, and certain gaps are reserved on the plate blanks and the cement tank wall to form a heat insulation layer so as to play a role in protecting the tank wall. At the lower ends of the plate blanks, stop iron and wedge iron are welded close to two sides of the plate blanks by using tank bottom steel plates to form inner wedge and outer stop; and the degree of freedom of the plate blanks is controlled, and the extension of the plate blanks is not affected, so that the stress of the plate blanks is fully released and the influence of expansion with heat and contraction with cold on the lining plate is eliminated. The plate blanks are connected by hooks and iron bars to form a whole. A door shape is welded on an embedded steel plate on the upper part so as to reinforce the upper parts of the plate blanks. The method stabilizes the structure of the lining plate, enables the lining plate to resist impact, reduces the damage rate of the lining plate, prolongs the service life of the lining plate, is convenient for construction, and can save a large amount of fund.

Description

technical field [0001] The invention relates to a method for installing and fixing a large lining plate of a hot stuffy pool for treating metallurgical steel slag, which is suitable for installation, fixing and maintenance of a large lining plate of a hot stuffy pool for hot stuffy process slag. Background technique [0002] At present, the more advanced method of processing steel slag at home and abroad is the hot stuffy process. This process requires several hot stuffy pools with large volumes to complete. The general volume is 5m*7m*5.4m. Rapid cooling and rapid heating, the thermal expansion and contraction of the steel plate is relatively large, so the metallurgical slab with a thickness of about 200 mm is generally used as the lining plate, and each lining plate is 5m*1.6m*0.2m The volume is relatively large, and the traditional fixing method mainly adopts A number of screws are pre-embedded on the pool wall, holes are drilled on the slab, and the slab is fixed on the ...
