Disxription:

 

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:Refractories for iron-making blast furnace?
Cement kilns?
Q:Which plant need to make refractory mould?
Q:What are the chemical composition of refractory cement?
Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
Q:what is the specs of thermal insulation refractory slab ?
thermal insulation refractory slab features wear proof, heat resistance, impact resistance, acid or alkali resistance, smoke resiatnce, fire proofing,fungi proofing, mould proof,anti-static. fireproof panel is generally used for countertops, tabletops, walls, cabinets, office furniture, wall hung cupboard. Common Specifications: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, thickness 0.6-1.2mm.
Q:What kind of material is good for cabinet fireproof board
Natural stone marble: Advantage: Rich color, texture is more soft, easy for cutting or molding; shortcomings: Because it is a natural formation, micro cracks will get easily broken. If sewage infiltrates in during production and transportation, it is difficult to clean and it will get cracked. In the daily cleaning, residue will be filled into the cracks when using cloth to clean. then the material will become breed bacteria. In the long process of the formation, natural stone material may cause harm to human health due to the formation of heavy mental which is radioactive.
Q:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
Q:which is better as household fireproof material ?
the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.
Q:Does refractory belong to stone, building materials or other?
It belongs to metallurgy and building material industries.
Q:What do refractory materials include?
It is so difficult.
Q:how to use boiler fireclay
Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
