Brown Fused Alumina for Refractory, BFA sands, Abrasives
is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials

If you’ve any enquiries, please don’t hesitate to let us know.
- Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- A less accurate view of the statement is probably the meaning of the “construction of refractory material" , for example, pouring castable can be called “knot”, the pounding of the construction can also be said that, so it is with spraying paint.
- Q:How much is refractory spraying coatings?
- This depends on whether you use the thin coatin or thick coating. Then it depends whether you use an aqueous coating or oily one. Usually thick aqueous coating is 2-3 dollars per kilogram. While the thin is six or seven dollars per kilogram. The oily coating is more than ten dollars. The prices obtained from the Internet is for reference only.
- Q:What are the raw materials of refractory?
- Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
- Q:Is refractory material harmful to human body?
- Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
- Q:what's the requirements of refractory for forge furnace?
- operating temperature of forge furnace is 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. general requirements for the properities of refractory: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
- Q:What are the requirements when producing fireproof materials by kaolin?
- Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
- Q:Refractory inquiries
- Acid refractory materials are commonly used brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used
- Q:What are the fire endurance requirements of class A fire resistant door ?
- Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.
- Q:On the problem of making refractory materials
- But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!
- Q:Which refractory is better for building 1500 degree kiln ?
- High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
