Details of anchoring high alumina brick

  1. The arrangement of anchoring high alumina bricks should be determined according to the range and frequency of temperature variation and the size of the area of the front wall, usually not less than 6 pieces /m2.
  2. The anchoring high alumina bricks must be carefully checked before masonry. If there is a crack in the anchoring hole that affects the overall strength of the anchoring bricks, the anchoring bricks cannot be used and should be resolutely abandoned.
  3. When masonry is close to the position of anchoring high alumina bricks, it should take the trouble to determine the exact position of anchoring high alumina bricks in advance. It is to use wire brush to thoroughly clean the welding part of the metal shell, use the welding rod suitable for the welding parts, and weld the anchoring pipe firmly.
  4. Insert the anchoring hook after the completion of the anchoring brick, and fill the air with refractory fiber felt and plug it tightly to form a certain protection for the anchoring parts.
