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: How much is one ton of high alumina refractory brick?
- High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
- Q: How to reduce porosity of high alumina brick
- High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
- Q: What are the requirements for refractory materials in heat treatment furnace?
- The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.
- Q: The difference between light high alumina brick and heavy aluminum brick
- High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- Q: What kind of material is the general metal case?
- We usually discuss the electromagnetic radiation of computer enclosures, mainly RF radiation, followed by MF leakage.Switch signal of RF radiation from computer high-speed leakage, such as one of the energy radiation is CPU frequency, graphics, display output line, keyboard, is the source of the operating characteristics of the computer leaked out, is also the main part of computer security.For the absorption of radio frequency radiation, the best is the use of copper materials, the use of other metals can also, thickness enough on the line.The most vulgar description is that people can sit in the case is a good thing.
- Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The physical and chemical properties of refractory materials used in rotary kiln are as follows: physical and chemical properties of refractory materials used in rotary kilnMaterial name: high temperature compressive strength (MPa), softening temperature (DEG C), thermal shock resistance (1100 DEG C, cold water), sub volume density (g/cm3)Magnesia spinel brick is greater than or equal to 50 is greater than or equal to 1700 = 12 = 2.95High alumina brick is greater than or equal to 75 = 1520 = 8 = 2.57High aluminum bricks more than 50 = 1700 = 12 = 1The clay brick is greater than or equal to 30 = 1400 = 12 = 2.30
- Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
