China Calcined Bauxite Ore Metallurgical Grade Bauxite for Cement Industry
Bauxite is a kind of earthy minerals, the main constituent is impurity hydrated alumina. It is white or
off-white, but it will appear tawny or light red because of adding iron.
Bauxite is extremely difficult to melt. It is insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution.

Application:
Bauxite is widely apply to refractories, aluminum silicate refractory fiber, precision casting, alumina smelting industry, bauxite cement, etc.
Our Advantages:
1. The bauxite ore is competitive price.
2. High purity.
- Q: Who know what kind of fire shutter fire rating are there?
- The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department
- Q: What are the standards of refractory concrete ?
- It can be divided into: 1. Ordinary refractory concrete Aggregates used include high alumina, clay, silica, basic materials (magnesite, chromite, dolomite, etc.) or special materials (carbon, silicon carbide, zircon, etc.). It can also use several combination of refractory material. 1. Thermal insulated refractory concrete It is mainly formulated with refractory light aggregates. The light aggregate used can be expanded perlite, vermiculite, ceramsite, porous chamotte, alumina hollow ball, etc. It can also be a combination of several refractory light aggregates or combination of the refractory aggregates. The aggluetination material used in refractory concrete can be high alumina cement, phosphate binders, water glass binder and clay, etc.
- Q: How to use fireclay?
- Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.
- Q: What's the poured refractory material?
- Frequently used poured refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia.
- Q: Does the refractory material used in steelmaking all refer to refractory brick?
- For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming?mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.
- Q: Which brand of AAA refractory is good?
- The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory?aggregate and porous refractory?aggregate, organic fiber and inorganic fiber.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you
- Q: What is the acceptance standard of refractory?
- Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
- Q: What's the A class fireproof and thermal inuslation matertial for external wall?
- It is roughly divided into thermal insulation mortar, phenolic foam board, rock wool board, foamed cement board, etc. Insulation mortar is quite good for its simple construction, convenience and low cost, but its production is too simple to make fake products easily. If you want to use the material, it is suggested to find a large plant with complete procedures such as provincal records of production and use, city records, test report above provincial levels, national fire inspection report, design drawings sheets of Department of Construction, etc. If there is lack of any one, it is unsafe. Hope my answer is helpful for you.
- Q: How do refractory materials apply into pyrophyllite?
- Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
