Anti corrosive of fused cast azs brick
The document discusses factors that affect the anti-corrosive properties of fused cast AZS brick. It states that anti-corrosive properties allow the brick to resist corrosion from substances like slag, fuel, and acids at high temperatures. The chemical composition, density, porosity, and conditions of use all impact a brick's resistance to corrosion. Multiple factors together determine the complex anti-corrosive abilities of refractory bricks.
The main content of zircon brick - zr o2
ZrO2 is the main oxide of zirconium, and it is a white crystalline which is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. ZrO2 is an important material of refractory with the characteristics of high melting point, high resistance coefficient, high refractive index and low thermal expansion coefficient.
Features during casting process of fused cast azs block
The casting process has a significant influence on the quality of fused cast AZS blocks. During casting, intense heat exchange and chemical reactions occur between the molten liquid and sand mold. This can lead to issues like porosity if the cavity pressure increases too much. Uneven molten liquid flow may also cause defects on the surface of the blocks. How the molten liquid fills the porous mold wall further impacts the final internal structure, potentially causing air holes or sand inclusions. The time of the casting process also affects the temperature distribution within the finished block.

The difference between insulation brick and refractory brick
- 1. The Difference Between Insulation Brick And Refractory Brick Insulation brick is mainly used for insulation and reducing heat loss, generally, insulation brick (mullite insulation brick, fire clay insulation brick, high alumina insulating brick) does not contact with the flame directly. However, refractory brick (zircon brick, fused cast azs block) contacts with flame directly, so refractory brick is mainly applied to withstand flame broiled. The main difference between insulation brick and refractory brick are as following: 1. Insulation property When the average temperature is at 350 ± 25 ,℃ the thermal conductivity of insulation brick is usually at 0.2-0.4 w/m.k, the thermal conductivity of insulation brick is above 1.0 w/m.k, thus can be drawn that the insulation property of insulation brick is better than refractory brick. 2. Refractoriness In general, the refractoriness of insulation brick is below 1400 degree, however refractory brick is above 1400 degree. 3. Density Insulation brick always adopts lightweight thermal insulation material as the raw material, and the density is about 0.8-1.0g/cm3. However, density of refractory brick is usually above 2.0g/cm3. In conclusion, refractory brick has high mechanical strength, dense structure, long service life, good corrosion resistance, low thermal expansion coefficient, high grinding efficiency, low pollution, excellent chemical stability which means that do not chemically react with the material, and high temperature performance and maximum heat temperature can reach 1900 .℃ In a word, there is a big difference between refractory brick and insulation brick, their using environment, range and role in glass furnace is different, and different place uses different material. So we need to choose proper refractory material according to our own actual situation when choosing refractory for our furnace. Zhengzhou Sunrise Refractory Co., Ltd. is mainly engaged in the research and development of refractory products. Sunrise can provide both insulation brick and refractory brick which contain Fused cast AZS 33#,36#,41#, fused cast α-βalumina, fused cast high zirconia block, silica brick, Mullite Insulation Brick, Fire Clay Insulation Brick, High Alumina Insulating Brick, magnesia brick, zircon brick, zircon mullite brick, mullite brick, sillimanite brick, etc. All products has passed the ISO international certified. Over 30 years producing and marketing experience, with reliable quality, competitive price and prompt delivery, Sunrise has established long-term business and cooperation relationship with many customers in different
