Anchor Bricks for Steel Rolling Heating Furnaces

Anchor bricks are divided into hanging bricks and bricks with holes. The anchor bricks are fired at high temperatures, with high strength, good erosion resistance, and high spalling resistance. It is an ordinary sintered brick. The role of anchor bricks is to anchor the refractory castables on the top of the heating furnace. The industrial furnace or flue wall is roughly composed of an inner lining layer, a heat insulation layer, and an outer wall layer. The inner lining is refractory bricks and the outer wall anchor bricks.

Anchor Bricks for Steel Rolling Heating Furnace

The alumina content of anchor bricks is more than 55%, and the alumina content of excellent anchor bricks can reach 75%. This kind of brick body has a soft load temperature of 1550°C, which is a high alumina refractory brick product. However, in general, the alumina content of 55% is more, because the 55% content of the anchor brick has better flexibility. In addition, it should be noted that anchor bricks are used to anchor refractory castables. The properties of anchor bricks should be consistent with the material of the castable, and the expansion and contraction should be consistent, so as to form a close combination with the castable and extend the life of the furnace lining.

Masonry of Anchor Bricks

The layout and masonry of anchor bricks during use should follow the following principles:

1. The arrangement of anchoring bricks should be determined according to the range and frequency of temperature changes and the size of the direct wall area. Usually, it should not be less than 6 blocks/m2.

2. The anchor bricks must be checked carefully before laying. If the anchor bricks have cracks at the anchor holes that affect the overall strength of the anchor bricks, they cannot be used and should be resolutely discarded.

3. When the masonry is close to the anchor brick position, bricks should be arranged in advance to determine the accurate position of the anchor brick. Use a wire brush to clean the welding part of the metal shell. Adopt the welding rod suitable for the welding parts, and weld the anchor pipe firmly.

4. After the anchoring brick is built, insert the anchoring hook, and fill the airstrike with refractory fiber felt, and plug it tightly. To form a certain degree of protection for the anchor.

The anchor brick includes a column composed of a hanging end and an anchor solid. Spaced partial grooves are opened on the surface of the anchor solid, and ribs are arranged along the length direction on at least one surface of the anchor solid. After the ribs are installed, due to the reinforcement and traction of the ribs, the tensile and flexural strength of the anchor solid is significantly improved, and the stress generated at the groove is blocked at the ribs and cannot be transmitted. Therefore, the anchor brick of this kind of structure is not easy to break.
