Brick inlaying method for fully covered thermal inlaid brick cooling wall

Abstract

The invention relates to the technical field of blast furnace cooling wall manufacture, in particular to a brick inlaying method for a fully covered thermal inlaid brick cooling wall. The brick inlaying method is characterized in that: inlaid bricks are inlaid into a wooden mould and then a sand mould is made, and the brick inlaying method comprises the specific steps of: 1) pasting fireproof asbestos paper onto the side face and the bottom face of each inlaid brick; 2) placing the inlaid bricks onto the wooden mould, making the inlaid bricks close to one another and putting a movable block into a hollow part at the dovetail-shaped bottom of each inlaid brick; 3) embedding the wooden mould into a sand box and firmly connecting the wooden mould with the sand box; and 4) filling moulding-sand resin sands into the sand box, turning the sand box and taking out the wooden mould after the moulding sands are solidified, and retaining the inlaid bricks in the sand mould. The brick inlaying method has the advantages that: 1) gaps among the inlaid bricks are eliminated, so cracks on the inlaid bricks caused by the entered metal solution can be avoided, and the quality and the qualification rate of the product are improved; and 2) the side face of the exposed part of each inlaid brick cannot be pasted by the metal, so the later processing work is reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing blast furnace staves, in particular to a brick-inserting method for a fully-covered thermal-brick-embedded stave. Background technique [0002] At present, the common full-coverage heat-inlaid brick cooling stave is composed of two parts: the stave body and the cast-in brick. The material of the main body is cast iron, cast steel, and cast copper. Clay bricks and silicon carbide bonded silicon nitride bricks, etc. The usual method of inlaying bricks is: cast the bricks with dovetail structure pasted with refractory fiber paper into the prepared sand mold, and then inject molten metal into the mold. The disadvantage of this method is that the bricks are not easy to rely on. Strict, it is easy to produce gaps. After pouring molten iron into the cavity, molten iron will seep into the gap between bricks and bricks, causing cracks in the inlaid bricks. The gap between the brick and the brick is...

The usual method of inlaying bricks is: cast the bricks with dovetail structure pasted with refractory fiber paper into the prepared sand mold, and then inject molten metal into the mold. The disadvantage of this method is that the bricks are not easy to rely on. Strict, it is easy to produce gaps. After pouring molten iron into the cavity, molten iron will seep into the gap between bricks and bricks, causing cracks in the inlaid bricks. The gap between the brick and the brick is the key to solving the problem
