Product Details

Product Description
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, 
hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.
From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt.
Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material. 

Usage 
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry,
daily necessities, etc. 
2 precision casting. Alumina clinker made after the mould precision casting processed into fine powder. 
Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department. 
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, 
and good physical properties. 
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability,
low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. 
Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, 
defense and other industries. 
(5) in magnesia and bauxite clinker as raw materials, add the appropriate binder, 
used for pouring ladle whole ladle lining has particularly good effects. 
(6) manufacture alumina cement, abrasive materials, 
ceramic industry and chemical industry can be aluminum of various compounds

Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
who knows the classification of fireproofing glasses, how long is the fire-resistant time?
Q:What kinds of refractory will be used in kiln of sintering ceramics?
Porcelain has many classes, including acid, alkaline and neutral materials.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.
Q:What are the electrical fire protection materials?
Flame retardant organic resin: They can be classied into PVC, vinyl chloride, chlorinated rubber, epoxy resin emulsion, epoxy resin, phenolic resin, etc.. Fire retardant additive: Phosphorus and halogens, nitrogen organic compounds (chlorinated paraffin, tributyl phosphate (TBP) and polybrominated diphenyl ethers) and boron (boric acid, zinc borate, boric acid aluminum), antimony, aluminum, zirconium inorganic compounds.
Q:What defect does fused cast refractories have ?
What defect doesfusion-cast refractory material have ? In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are sidewall block and brick kiln bottom. I hope my answer can help you.
Q:What are the refractories for converter?
Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
Q:What are the materials of insulation firebricks?
The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
Q:What refractories are accessible with ease in daily life?
Basically there have all materials. But it depends on your needs.
Q:The development prospect of fire-resistant material
Luweishi (Furnace guardian)--- the wings ofrefractory material (blast furnace for high pressure grouting and liningmaking)--- is the fortune of furnace repair companies. Nowadays the sales of refractorymaterial are very difficult, but furnace repairing is popular. It does not onlyearn money but also sell refractory material, and even establish long-term,stable and interdependent business relations provided the price is acceptable.Many forward-looking companies such as Beijing Rongda, Anshan Yongheng, WuahnKehong, Shandong Zhangqiu, Gongyi Huaxi, Hongda, Zibo Xinfu and Anyang Tecai,allowing for the steel mills which are rich and try to do things the easy way, turnrefractory plant into or include into building company, resulting in greatsuccess in the bid invitation among so many units. Junwei can provide quality and efficient blast furnace equipment for grouting and lininLuweishi--- Luweishi (Furnace guardian) and research, design and manufacture as required. QQ:76350883
