The aluminum alumina content of anchor refractory fire bricks is above 55%, and the content of high -quality anchor bricks can reach 75%. The weight softening temperature of this type of brick is 1550 ° C, which is an excellent refractory brick product. However, in a case, the aluminum alumina content is 55%, because the 55%content of anchoring bricks is better.
In addition, it should be noted that anchoring refractory fire bricks are used for anchoring fire -resistant pouring materials. The performance of the anchor refractory fire bricks should be consistent with the pouring material, and the expansion and contraction should be consistent, so that it can form a close combination with the pouring materials to extend the lining life.
The layout and masonry of the anchor bricks during use should follow the following principles:
1. The arrangement of anchor refractory fire bricks should be determined according to the range and frequency of temperature and the size of the direct wall area, and it should not be less than 6 yuan/m2.
2. Before the masonry, you must carefully check the anchor brick. If the anchoring bricks cannot be used when the anchoring hole affects the overall strength of the anchor brick, it should be resolutely abandoned.
3. When masonry to the position close to the anchor refractory fire brick, the pre -draining brick that is annoying to determine the accurate position of the anchor brick. It is a welding site for thoroughly cleaning the metal shell with a wire. Good anchor tube.
4. After the anchor brick is completed, the anchor hook is inserted, and the fire -resistant fiber felt fills the air strike and tightened to form a certain protection of anchor parts.
The anchor refractory fire bricks include a pillar composed of a hanging end and anchoring body. The grooves of the interval sub -parts on the solid surface are opened. At least one surface of the anchoring body is set along the length of the length of the length of the direction. The reinforcement and pulling effect of the strip, the anchor -resistant tensile resistance strength is significantly improved, and the stress generated at the groove can be obtained at the tendon bar and cannot continue to be passed.
