What to avoid during огнеупорный кирпич строительство

(1) Dislocation: that is, unevenness between layers and blocks;

(2) Tilt: that is, it is not flat in the horizontal direction;

(3) Uneven ash seams: that is, the width of ash seams is different, which can be adjusted by selecting bricks appropriately;

(4) Climbing: that is, there are regular irregularities on the surface of the circular wall, which should be controlled within 1mm;

(5) Separation: that is, the refractory brick ring is not concentric with the shell in the arc-shaped masonry;

(6) Re-stitching: that is, the upper and lower ash seams are superimposed, and only one ash seam is allowed between the two layers;

(7) Through seam: that is, the gray seams of the inner and outer horizontal layers are combined, and even the metal shell is exposed, which is not allowed;

(8) Opening mouth: that is, the mortar joints in the curved masonry are small in size and large in size;

(9) Voiding: that is, the mortar is not full between the layers, between the bricks and between the shell, and it is not allowed in the lining of the immovable equipment;

(10) Hairy joints: that is, the joints of the bricks are not hooked and wiped, and the wall is not clean;

(11) Snaking: that is, longitudinal seams, circular seams or horizontal seams are not straight, but wavy;

(12) Masonry bulge: It is caused by the deformation of the equipment, and the relevant surface of the equipment should be smoothed during the masonry. When building double-layer lining, the insulation layer can be used for leveling;

(13) Refractory mixing slurry: the wrong use of slurry is not allowed.
