Heavy Duty Fire Brick

High aluminum heavy duty fire brick is the product of high temperature forging and burning, this process is divided into several stages, the key is the removal of water and the dissolution of hydrochemical structure water at 500 ° C in the kiln, and the temperature can be accelerated. During the 500-1200℃ period, the fusion effect of the chemical agent has been lost, and the high performance liquid phase has not been converted into, and the crack of the body is low. At 1200-1400℃, solid phase reaction is generated, liquid mutual conversion, and the product is fired and formed, but the crack of the billet is still low, and the temperature increase speed is too fast. When the magnesite is processed and hardened at about 1400℃, it will produce plastic deformation and shape, at this time, the cracking is low, the kiln avoids the unique flame impact, and the temperature kiln is slow. At 1500-1600℃, the product section is calcined..
