Product Introduction
Cobn
White fused alumina 325# for refractory is made of high-quality aluminium powder as raw material,which is refined and crystallized by electrofusion.
Characteristics:
1.High purity
2.Low calorific value
3.Good self-sharpening
4.Strong grinding ability
5.Its toughness is slightly lower.
6.High efficiency,acid and alkali corrosion resistance
7.High temperature resistance and stable thermal performance.
Application:
1.It is used to make abrasive tools
2.It is suitable for fine-grained abrasives
3.It can also be precision casting and advanced refractories
4..It is suitable for grinding high-carbon and high-speed steel,stainless steel 
White corundum fine powder: It belongs to white corundum segment sand.
The products with a particle size of 0 to a certain particle size in the segment sand are also called fine powder. They are the products that pass through the finest screen in the white corundum segment sand production line.
The general models are: 100#-0 , 200#-0, 320#-0, 0-1mm.
It can be used as high-quality refractory powder for shaped refractories and unshaped refractories.
At the same time, white corundum fine powder can also be further ground, processed and sieved into white corundum sand and white corundum fine powder.

1.White fused alumina 325# for refractory is made of high-quality aluminium powder, which is suitable for chromium oxide after high temperature smelting.
Chromium corundum is pink in color, and its hardness is similar to that of white corundum, and its toughness is higher than that of white corundum. White corundum is made of grinding tools, with good wear resistance and high grinding precision.
Precision grinding for measuring tools, machine tool spindles, instrument parts, threaded parts and template grinding.
2. White corundum In the metallurgical industry, chromite is mainly used to produce ferrochromium and metallic chromium.
As an additive to steel, ferrochrome produces various special steels with high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance, such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel and tool steel.
3. Metal chromium is mainly used for smelting special alloys, such as cobalt, nickel and tungsten and other elements.
These special steels and special alloys are indispensable materials for aerospace, aerospace, automotive, shipbuilding and marine.
In refractory materials, chromite is used to make chrome bricks, chrome-magnesium bricks and other special refractories.
