|Description of bauxite buyer|
There are several different models of raw bauxite,we own have three bauxite quarry,and can produce 5000 tons bauxite per month.
|Classification of bauxite buyer |
Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.
|3. Rotary calcined bauxite:|
Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.
|4. Shaft kiln calcined bauxite:|
Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom.

- Q:What's the fire endurance of hollow brick?
- For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
- Q:What are the types of steel refractory materials
- Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials
Alumina-magnesia castable is OK for small steel ladle
- Q:What types does refractory floor include?
- There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
- Q:What are Grade-A waterproof inorganic thermal insulation materials?
- Grade-A waterproof inorganic thermal insulation materials include: 1. external wall thermal insulation materials: (1) silicate thermal insulation material (2) gelatine powder polyphenyl granule (3) steel wire gauze picking cement cystosepiment (Estazolam plate) (4) extruded sheet; 2. roofing materials: (1) XPS Extruded sheet (2) EPS cystosepiment (3) perlite and perlite bricks (4) vermiculite brick; 3. heating and air conditioning material: PUR, rubberplastic sponge, polystyrene foam, glass wool, rock wool; 4. steel structure material: polystyrene, extruded board, polyurethane board, glass wool roll mat, etc.
- Q:what's the seal of fireproofing material?
- Folded organic putty takes organic material as bond,it has certain flexibility or plasticity while using, and it's products are thick liquid or cement shaped object. Folded WXY-II is powered solid that takes inorganic materials as main components, it has certain workability while used with admixture. Folded fire retardant bag is the packaged object made by fireproofing material, and it's suitable for fireproofing seal of larger openings or fire separation of cable bridge(fire retardant bag also refers to fireproof bag) Folded fire retardant module is the solid made by fireproofing material with certain shape and size, and it is easy for cutting and drilling, suitable for fireproofing seal of opening and cable bridge. Folded seal board is made by fireproofing material, it's easy for cutting and drilling, suitable for fireproofing seal of large opening. Folded foam seal is a kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Folded sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Folded sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Folded fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe.

Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
- Q:What are the main components of refractory cement?
- Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. 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. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
- Q:How to divide fire rating of decorating materials ?
- The combustion performance of building materials is divided into the following grades by the national standard GB8624-97: level A: incombustible building materials, almost no burning material. Level B1: Flame retardant building materials, such kind of materials are effective in flame retardance. It is difficult to fire in the air in the case of open flame or under high temperature, it is not easy to spread quickly, and when the fire source is removed , the fire stopped immediately. Level B2: combustible building materials. Combustible building materials are effective in flame retardance. It will immediately burst into flames in the air in case of fire or under high temperature, and it is inclined to lead to the spread of fire, such as wooden, wooden frame, beams, wood stairs,etc. Level B3: Flammable building materials: they have no effect in flame retardance, easy to burn, fire risk is very huge.
- Q:How about the prospect of refractory material?
- Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
