Calcined Bauxite Grade:

1.Refractory Grade:

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: 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: who knows the fire resistant levels of fireproofing glass?: Fireproofing glass is a kind of special glass which can keep its integrity in the regular fire resistance test, and it can be divided into three classes: fireproofing glass,fireproofing glass A class is a kind of fireproofing glass that can satisfy the requirements of refractory integrity, fire resistance and thermal insulation. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. hope it can help you.

Q: Concrete composition and function of magnesia bond used in refractory: The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick

Q: How much is the duration of fire resistance of the porous brick shale?: This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.

Q: What's the heat conductivity coefficient of fire-resistant material?: The heat conductivity coefficient of fire resistant material is related to bulk density and mainly related to the internal structure. Different materials have different structure and thermal conductivity and temperature . Carbonaceous material can be used for heat dissipation and reach more than 15. For thermal insulation it can be 0.00.

Q: The difference between refractory and thermal insulation material: Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.

Q: What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?: The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.

Q: Does anyone know about the A-level fireproof materials?: A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.

Q: how does the fire endurance of first rate fire resistant window?: how does the fire endurance of first rate fire resistant window? I really don't know it and I need a specific direct and detailed answer!
