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
Q2: What`s the lead time for my order?
A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets
- Q: Application of electric high temperature regulating valve?
- Now, the definition of refractories has not only depended on the degree of refractoriness is more than 1580 degrees celsius. At present, refractory materials refer to inorganic non-metallic materials used in metallurgy, petrochemical, cement, ceramics and other production equipment lining.
- Q: What is the main component of corundum?
- The name of corundum originates from India and is the name of mineralogy. There are three main variants of corundum Al2O3, which are alpha -Al2O3, beta -Al2O3 and gamma -Al2O3 respectively. Corundum is second only to diamond.
- Q: What material is used in an iron smelting furnace?
- Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.
- Q: Wave tile and throwing glaze, tile which good?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q: Is liquid phosphoric acid two aluminum hydrogen flammable?
- Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable
- 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: How do corundum bricks bind?
- High temperature bonding clay can be used for bonding masonry
- Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?
- High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
- Q: What are the refractory materials?
- Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
- Q: What kind of rock is corundum produced?
- Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;
