Bauxite is a natural, very hard mineral used predominantly in road systems for its high-friction and anti-skid properties. The majority of public sector systems will specify that Calcined Bauxite be used in their road and pedestrian crossing installations.

Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.

Pigmented Bauxite, which is produced in-house and is available in the main safety colours, is used to give an element of high visibility to anti-slip and anti-skid decorative surfaces.

1.0 - 3.0mm particle size is shown for pigmented bauxite.

It is used extensively in warehouses, loading areas, high visibility pedestrian and vehicular safety areas.

What can bauxite do?

1. Aluminum industry.

2. Precision casting.

3. Refractory industry.

4. Silica acid aluminum firefibre

5. Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining

6. Manufacture bauxite cement,grinding abrasives.

7. Ceramic industry,and chemical industry for making aluminium compounds

Q:Is the ball mill used in production of refractories?: It depends on what refractory you produce.

Q:What are the characteristics of clay refractory materials?: Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.

Q:What's the poured refractory material?: According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.

Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?: Metallurgical industry and refractory industry.

Q:What are the refractories for converter?: Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick

Q:What are the characteristics of magnesium fireproof plate: Features: Glass magnesium plate is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation. The plate is easy to decorate, has high strength, good flexibility when bending, and can be nailed, sawed, glued It can also be made into thermal insulation materials with a variety of compround composite insulation plate. Characteristic: Magnesium plate glass is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation High strength, flexibility when bending, convenient for decoration. It can be sawed, nailed, and glued.

Q:What refractory material does cupola lining use?: In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.

Q:How many hours of the fire endurance time of the rock wool laminboard?: The fire endurance time of the rock wool laminboard is generally adout 1 or 2 hours.

Q:The effect of a high content of water in liquid resin exerted on refractory material?: For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.

Q:What are the fire protection standards of insulation materials?: The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.
