Which industrial fields are brown fused alumina used in?
Brown fused alumina is called the tooth of industry: it is mainly used in refractory materials, grinding wheels, and sandblasting.
Brown fused alumina is called the tooth of industry: it is mainly used in refractory materials, grinding wheels, and sandblasting.
There are generally two types of brown fused alumina on the market : one is natural and the other is artificial. There are two main types of natural brown corundum in terms of texture: one is sedimentary sandstone, and the other is hard slate. Artificial brown fused alumina is also made of the essence of natural brown fused alumina and cast from inorganic materials. It is very realistic and natural to touch every trace of natural brown fused alumina.
Brown corundum Commonly used grinding methods can generally be divided into three categories: wet research, dry research and semi-dry research. Let’s take a look at each of them:
When we talk about brown Brown corundum abrasives When it comes to performance, we often mention hardness, content, etc., including different grades of brown molten alumina hardness mentioned in the previous article, but rarely mention its other property. -Toughness. But in fact, the toughness of brown molten alumina is also a very important attribute. Then let’s discuss the significance of this elasticity for brown molten alumina.
Brown fused alumina is made of bauxite, anthracite and iron filings, and is smelted at high temperature in an electric arc furnace. During the smelting process, the carbon in the anthracite reduces impurities such as silicon oxide, iron oxide, and titanium oxide in the bauxite to metals, and these metals are combined to form a ferroalloy, which settles to the bottom of the furnace due to its larger specific gravity than the corundum solution. The corundum solution separates. Only a small amount of impurities are included in the corundum frit.
White corundum fine powder is very suitable for wet sandblasting and polishing operations, does not affect the color of the workpiece, can be used for prohibited processing of iron powder residue, fast processing speed, good quality, low iron oxide content, suitable for PR sandblasting operations. Suppresses iron powder residue. Can be used repeatedly as sandblasting abrasive. The number of times it is used is related to the blasting material, the particle size of the micropowder, and the hardness and level of the micropowder.
Briefly introduce the difference between green silicon carbide and black silicon carbide : silicon carbide has two commonly used basic varieties, black silicon carbide and green silicon carbide, both of which belong to α-SiC. Green silicon carbide is basically the same as black silicon carbide, but the raw materials and manufacturing process are different. The product is green and translucent, and its hardness and purity are better than black silicon carbide.
As an ideal raw material for non-metallic materials,Green silicon carbide powder It is undoubtedly a widely used raw material, what are its use steps and methods?
Brown corundum, like white corundum, is also made of alumina powder as the main raw material, suitable for chromium oxide, etc., and smelted at high temperature. However, because of their smelting methods and properties are slightly different, resulting in certain differences in their use process, the following Haixu Abrasives Xiaobian will introduce to you:White corundum Sandblasting is the difference from brown corundum sandblasting.
Green silicon carbide Which one is good? When it comes to green silicon carbide, people who make abrasives must be familiar with it, and green silicon carbide has a very important role in the abrasive industry. So which green silicon carbide is better?Green silicon carbideWhat are the production processes and uses?
