Anchor Brick for Industrial Furnace

Anchor brick is a type of refractory brick for the roof of industrial furnaces, which includes a pillar composed of a hanging end and an anchor. The grooves distributed at intervals on the surface of the anchor body are provided with ribs along at least one surface of the anchor body along the length direction. After the ribs are provided, due to the reinforcement and pulling action of the ribs, the tensile strength of the anchor brick body is improved. Obviously, the stress generated in the groove is blocked at the ribs and cannot be transmitted, so the anchor brick of this structure is not easy to break.

  2. The anchor bricks must be carefully inspected before masonry. If there are cracks in the anchoring holes that affect the overall strength of the anchor bricks, they cannot be used, and they should be discarded firmly.
  3. When the masonry is close to the position of the anchor bricks, it is necessary to arrange the bricks in advance to determine the exact position of the anchor bricks.
  4. Use a wire brush to thoroughly clean the welding part of the metal shell, and use welding rods suitable for the welding parts to firmly weld the anchor pipe.
  5. Insert the anchor hook after the completion of the anchor brick, and fill the air raid with the refractory fiber felt and plug it tightly to form a certain protection for the anchor.
