Application of Neutral Alumina Refractory Bricks in Kilns

by

Neutral refractories are primarily composed of mullite, corundum, or carbon (Al₂O₃, ZrO₂, CrO₃, SiC) as the main crystalline phase. At high temperatures, they exhibit good resistance to the chemical reactions of acidic slag, alkaline slag, fluxes, and other refractory materials, which can corrode other refractories. Strictly speaking, neutral refractories refer only to carbonaceous refractories, including … Read more

Application of High-Alumina Refractory Materials in Various High-Temperature Industries

The Relationship between the Color and Quality of High Alumina Bricks

by

The red color of the surface of high-alumina bricks mainly comes from various factors during the firing process. In the sintering process, the placement of the brick blank is very important. If the brick blank is at the fire head position, the upper position, or the temperature adjustment is unstable during sintering, it is very … Read more

Anchor Bricks are the Link between Stability and Safety in Refractory Lining

by

As the name implies, anchor bricks are mainly used for anchoring. They are carefully designed and placed in the lining structure of the furnace to firmly fix the refractory materials so that they can withstand extreme conditions such as high temperature, chemical erosion, and mechanical stress. During the operation of the furnace, anchor bricks can … Read more
