Description of Brown Fused Alumina for Refractory Use, Sandblasting, Abrasives:

Brown fused alumina is made from Calcined Bauxite. It is hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media. Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.

 

 Application of Brown Fused Alumina for Refractory Use, Sandblasting, Abrasives

Resin ceramic abrasive, sand blasting, grinding and polishing, and is widely used in anti-wear runways, high-temperature coating matrix and metallurgy, chemical industry, and other high-level furnace refractories.

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:Can anyone tell me what is A-leve fireproof material?
What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
Q:what textures of furnace refractories are good?
Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.
Q:What's the organzational structure of refractory material?
Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition
Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
Q:What dose the fireproof and thermal insulation material include?
Currently the non-combustible insulation materials for external insulation system mainly are foam insulation board, composite cement foam insulation board, aerated concrete panels, rock wool board (strip), and inorganic insulation materials. 1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
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℃.
