Spray the internal combustion type enclosure first, and then start masonry lattice bricks. When masonry, the multi-circle wall should be masonry from the inside to the outside, the inner circle of bricks first, the outer circle of bricks close to the inner circle of lattice bricks for masonry. The gap between the water-stopping bricks and the mortar layer should be solidified with asbestos board or filler, and the top surface of the filler should not be lower than the surface of the masonry by 500mm.


When masonry external combustion hot air furnace enclosure, it should be masonry according to the center line. The enclosure structure composed of multiple rings is built from the outer ring brick layer to the inner ring brick layer, and the flatness of the inner radius of the brick layer should be confirmed during masonry. When the inner ring is built with brick masonry, the elevation of the brick layer should be marked on the heat-insulating refractory brick layer.





Regenerator grid brick is generally seven-hole grid brick, masonry should be staggered in each layer, the upper and lower grid holes should be flush. Before masonry should be according to the design size of the enclosure edge location and connection of the grid brick pre-sorting and marking.


Before lattice brick masonry, in the wall masonry 0 degree , 90 degree , 180 degree , 270 degree four angles to pull out the cross center line, and then in the 90 degree , 270 degree line on both sides of the two columns of masonry center. Line, the center line is listed as the center line of the first column of masonry.


The first layer of lattice bricks is pre-laid using the dry placement method. After checking its center position accurately and qualified, formal masonry. After completing the masonry and confirming that the surface flatness of the masonry meets the requirements, start laying the second layer of lattice bricks....


Expansion joints between lattice bricks should be 4mm for clay lattice bricks, 8mm for high alumina lattice bricks, and 12mm for siliceous lattice bricks. fill the expansion joints with yellow cardboard or foam boards, and stick the expansion joint boards on the side of lattice bricks, and paste them while laying.
