Aluminum Oxide Abrasive Blasting Grit - China

Artificial corundum is divided into brown aluminium oxide (A), white corundum (WA), chrome corundum (PA), zirconium corundum (ZA), black corundum (BA), single crystal corundum (SA), microcrystalline corundum (MA) and the like.

The brown corundum is mainly made of bauxite, iron filings and anthracite in the electric arc furnace by smelting and reducing impurities.

The white corundum is obtained by melt crystallization of the aluminum oxide powder in the electric arc furnace.

The other corundum is in the melting process with different alumina contents.

A certain amount of other oxide-derived substances having different properties are added.

A large number of corundum applications are brown corundum and white corundum.

A variety of abrasives such as white corundum, brown fused alumina price, green silicon carbide, and black silicon carbide are also in full swing.

In 1934, boron carbide with hardness higher than corundum and silicon carbide appeared.

In 1936, a semi-crunchy corundum between white corundum and brown corundum appeared.

At the same time, a metal bond natural diamond grinding wheel was produced.

In 1946, white alumina was born.

In 1954, the United States GE, Kaplenden and Norton worked together to make a device that can reproduce diamonds.

Abrasives as a special industry, there are problems of abrasive smelting in energy saving and emission reduction.

At present, there is overcapacity in domestic brown fused alumina.

With the implementation of national energy conservation and emission reduction policies, the next policy focus will be to eliminate the pink corundum industry.

Outdated production capacity.

In the past five years, the development of emerging industries has brought more opportunities for super-hard materials, and super-hard materials have developed toward a wider and more sophisticated application.

In recent years, domestic abrasives and abrasives have been continuously improved, and the domestic machine tool industry has become an important pointer to break foreign monopoly.

At the same time, in the fields of shipbuilding and aerospace industry, a group of high-tech abrasives and white fused alumina abrasives enterprises have shown their talents.

Domestically produced products have gradually replaced imported products, and their performance has even surpassed that of foreign products of the same type.

Although we have made major breakthroughs in many fields of abrasives, overall, there is still a big gap between the high-end of abrasives and the world's advanced level.

Machining surface quality refers to the microscopic unevenness of the machined surface after machining, also called roughness.

The surface quality after machining directly affects the physical, chemical and mechanical properties of the machined part.

The performance, reliability and longevity of the black aluminum oxide product depend to a large extent on the surface quality of the main part.

Therefore, it is of great significance to correctly understand the connotation of the surface quality of the parts, analyze various process factors affecting the quality of the machined surface during machining, improve the surface quality and improve the performance of the products.

At present, the situation of domestic brown fused alumina is overcapacity.

The next step of the national policy will be to eliminate the backward production capacity of the white aluminum oxide industry, shut down some high-energy small and medium corundum production enterprises, eliminate the low-power smelting furnace, and encourage the advantageous enterprises to become stronger.

Be big.

Zhang Wei, secretary-general of the Guiyang Abrasives Association, bluntly said that some of the domestic abrasives companies still have some backward production equipment that is banned from use in the country, and will continue to be used for this part of the enterprise.
