| 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.
Application:
1.Aluminium metallurgy.
2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.
3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.
It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)
4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace. After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
7.Abrasives.
8.Ceramics industry.
9.Chemistry industry for all kinds of aluminium compound.

- Q: How can refractory material of the electric furnace be used for longer.
- I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
- Q: How much is the content of boron carbide in refractory material?
- Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,
- Q: how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate refractory fiber board has following characteristics:1. the structure is more even than natural wood. it avoids rot, moth-eaten and other problems, 2. fiber board has small expansion and contraction, which is easy to be processed. 3. its smooth surface is easy to paste a variety of finishings and you can make furniture more beautiful. Decorative wood-based panel is to embellish their homes. I hope it is useful to you!
- Q: For refractory knowledge. What is the ratio of clay ramming?mass?
- Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
- Q: What's the organzational structure of refractory material?
- Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Big business needs to be usedIntroduce several big: Jiuzhou 208827 and Changhong
- Q: What materials are needed to make the amorphous refractory bricks?
- Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.
- Q: I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
- the fire endurance of fire window is: class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, Class C window is not less than 0.6 hour. technical requirements: 1, materials and accessories (1) the window frame is made by a certain strength of steel frame or wooden frame which is sufficient to safeguard the integrity and stability. (2) steel frame and mound layer can select galvanized?steel?sheet or stainless steel plate. Its selection standards should be in line with the provisions of Article 5.1. in GB12955 "Steel Fireproof Door General Technical Condition" (3) the selection standards of wood frame and mound layer should be consistent with the provisions of Article 5.1.1. in GB14101 "General Technical Conditions of Wooden Fireproof Door" (4 ) the inner filling material of steel and wood frame should be non-combustible material. (5) fireproofing glass can choose the qualified products in fire resistance test and not affecting the fire windows. light transmittance of glass is not less than 75% of identical layers of ordinary plate glass. ( 6) a sealing material between the frame and the fireproofing glass should use the nonflammable material, it can play the role of fireproofing and smoke insulation in the fire disaster. I hope I can help you
- Q: What kind of foundry ingot refractory materials are there? Please be more detailed.
- This question is a little bit extensive, because there are too much foundry ingot refractory materials.
- Q: I wanna ask about the thermal insulation material fire resistant level?
- The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.
