Production & Quality
1.Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packing shipment
2.Quality Control
a.According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.

- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q: Application characteristics of high alumina brick
- Load softening temperature. The softening temperature of high alumina brick products decreases with the increase of silica and alkali metal oxide content, but is higher than that of clay brick products, which is about 1420 - 1530 degrees centigrade. Al2O3. The softening temperature of corundum brick with content greater than 95% can reach above 1600 DEG C.
- Q: The difference between aluminium refractory and magnesia refractory
- Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
- Q: What are the characteristics of high alumina bricks?
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
- Q: How much is one ton / ton of high alumina refractory brick?
- The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012
- Q: What is spalling resistant high alumina brick?
- Spalling resistant high alumina brick is a kind of high alumina brick. Antistripping high alumina brick with high grade bauxite and containing Zr02 synthesis as raw material, according to a certain proportion by high pressure molding system in sintering products, products with anti stripping ability, and have the anti erosion potassium, sodium, sulfur, chlorine and alkali salt, low thermal conductivity and other properties that is the transition zone of cement kiln and decomposition of ideal material with remarkable characteristics, the product is good thermal shock resistance, strong ability to adapt to the environment. It is used in the preheating or decomposing furnace, grate cooler and so on.
- Q: The difference between ordinary and diatomite brick refractory brick
- To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- Q: What kind of material is the general metal case?
- Generally speaking, the outer surface of the case is usually made of a steel plate of more than 1 millimeters. The thickness and the material of the steel plate are directly related to the rigidity of the case, as well as the capability of sound insulation and anti electromagnetic radiation. The regular manufacturers of the chassis plate thickness not less than 1.3mm, but there are also some small manufacturers with a thickness of only about 1mm steel, we do not need the ruler to the amount, as long as you put him up, the more weight in the same volume of the chassis is better, in addition, we can also use the finger bomb case shell. If you can hear the crisp percussion sound proof of the casing plate is thin and brittle, if you hear is relatively dull and heavy sound that the chassis material must be good, good general steel plate coated with a layer of thin zinc (bright part), so it can withstand high strength, impact resistance, hardness high elasticity. The frame parts of the chassis are made of high quality materials with high hardness. They are bent into angle shapes or strip shapes. We can shake the chassis frame of the case by hand. Good chassis should be relatively stable, and inferior chassis light is easy to shake. When choosing, we should also pay attention to the outer edge of the case and the edge of the inner bracket. Whether the incision is smooth or not, a good case will not appear in the case of rough edges, sharp edges, burrs and so on. While the poor case appears above phenomenon, often appear when installing the blood splattered". Generally speaking, the chassis must go through the corresponding grinding process before leaving the factory. The edge of the flat plate some burr, edges and corners are rounded, the corresponding fold some corner. When you install such a case, you don't worry about cuts, and some rough, poorly built cabinets tend to scratch your hands.
