3. 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: What advantage and disadvantages it has compared to common fire insulation materials
Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.
Q: What is the upper temperature limit for refractory materials?
Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.
Q: What are some of the new refractories and what are their characteristics?
Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.
Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?
Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.
Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?
Metallurgical industry and refractory industry.
Q: How to classify the grade of wall fireproof and thermal inuslation matertial?
To sum up three versions of GB8624 (1997, 2006, 2011), fire?rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire?rating of external wall thermal insulation materials.
Q: What material is used to make furnace pipe of refractory bricks?
Furnace pipe of refractory brick is an indispensable part of casting cupola. Furnace pipe is divided into upper and lower part. Radial direction and axial breathing. The upper furnace pipe adopts double layer steel structure and countercurrent air supply mode. The lower furnace pipe is made by processing integrated heat resistant steel in flange, fin and inner wall in wearing parts. The operation life is over 3000h. There is radiating rib of heating air on the edge of furnace pipe liner by using the heat of casting cupola to heat air in cupola. Hot air temperature is about 180-250℃, which contributes to improve trhe thermal efficiency of production equipment, decrease production cost and improve economic benefit of enterprises.
Q: What kind of materials are needed to make refractory bricks?
Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.
Q: Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
