FAQ
Q1: How do you control the products quality?
A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.
From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis
Q5: Can you give me a brief introduction of the application of your products?
A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.
- Q: What kind of fused corundum corundum brick should be used for each part of the glass furnace?
- AZS33 is the casting of AZS series of the largest, most widely used in tea, to prevent the pollution of liquid glass is excellent. Widely used in the glass furnace pool wall, pool bottom, the upper structure and feeding routes and other parts.
- Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
- Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
- Q: What are the advantages of refractories?
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials. For example, AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on
- Q: Which is good, glazed brick and whole cast glazed brick?
- These two tiles have their respective advantages and disadvantages, in fact, to say which kind of good, mainly depends on the decoration of personal preferences and the location of the shop. If it is only the shop wall, then design and pattern rich whole glazed tile is good, it can make the room impressive, improve decorative effect, make the decoration style to fit the characteristics of his personality. In addition, clean up is relatively easy, not easy to contaminated with oil stains and other pollutants. If you are laying tile, suggested the use of tiles, tiles of good antiskid effect, water absorption rate is relatively low, so the kitchen toilet bathroom and other wet places is not easy to water seepage, improve the convenience of life.
- Q: What refractory materials are adopted in each part of the blast furnace?
- The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick.
- Q: What is the hardness of corundum refractory bricks?
- Corundum refractory brick has good stability against acid and alkaline slag, metal and glass solution. It can be used in oxidizing atmosphere at high temperature or in a reductive atmosphere. The basic material of corundum refractory brick is fused alumina or sintered corundum.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- Q: What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
- Fused zirconia corundum brick has a strong resistance to glass liquid corrosion!It is better to fuse the furnace with fused zirconia corundum bricks.Fused zirconia corundum brick, regardless of the size of the furnace, the use of small hundreds of kilograms can be used, depending on the design of the kiln!
- Q: What are the main constituents of refractory bricks?
- Brick, refractory brick is containing more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
- Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?
- The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
