Make full use of raw materials resources, and ordinary White Fused Alumina mill ceramic grinding gear, which is made of low temperature, generally contains more melt ingredients in its formula composition. Our country's local raw materials are relatively abundant. These local raw materials or low -quality raw materials (such as porcelain soil (such as porcelain soil Tailings, low -quality talcs, etc.) and some newly developed raw materials (such as silicon ash, transparent pyloric pirates, sunstone positive rocks, lithium mineral raw materials, etc.) often contain more low -melting point components,and rich sources. The price is low, quickly burn into White Fused Alumina abrasive ceramic grinding utensils. Therefore, low -temperature firing can make full use of raw material resources and promote the development and utilization of new types of WFA mill ceramics grinding utensils.
White Fused Alumina process process is based on industrial aluminum oxide powder. It is made of cooler after being refined by high temperature above 2000 degrees in the arc. When the particles are formed sharp, when the low temperature is fired, White Fused Alumina and silicon carbide mill will not have redness, iron spots and other phenomena, and silicon carbide mills are not easy to produce "black hearts", which is conducive to the commodity of the mill.
Most of the White Fused Alumina mill ceramic grinders are burned with high temperature of about 1250 ~ 1300 ° C. And for SIC mill, high -temperature firing high hardness part is prone to "black heart". In order to avoid the "black heart" produce a sintering binding agent that often uses a relatively large acid and alkali. At this time, a large number of binding agents must be introduced to achieve the high hardness required by the abrasive. The dust is large and the grinding performance is not good. Low -temperature firing can also prevent the decomposition from the FEC3 in SIC mills, and it can also reduce the decomposition of SIC mills, thereby preventing the redness and black heart phenomenon of SIC abrasives, and improving the inner and appearance quality of the SIC mill. White Fused Alumina important physical attributes: good thermal stability, more than 1750 degrees high temperature resistance, high purity, good self -sharpness, strong grinding ability, small heat emission, high efficiency, and acid -alkali corrosion.
Electric melting White Fused Alumina is a medium and high -grade refractory raw material. It has the advantages of white color, white and eye -catching, with high volume density, low pores, etc., which can effectively improve the volume stability and thermal shock performance of the material. Electric melting White Fused Alumina is the main raw material for producing mid -to -high -end irregularities and fixed refractory materials. It is used for large -scale steel bag pouring materials, mid -to -high -end iron groove pouring materials, spray supplements, prefabricated pieces and other irregular refractory materials. Mullite, refined with porous brick bricks, overall spray guns and composite water mouths, high -temperature industrial kiln lining materials and other kinds of abrasive products. It is widely used in steel, cement, ceramics, abrasives, petrochemicals and other industries.
Electric melting Fused Alumina is a professional name. Its English abbreviation is AZS. I try to explain the words of this professional in an easy -to -understand vernacular. Otherwise, everyone will not be exposed to this industry. Essence
The "melting aluminum" is usually referred to as "electric melting white gangster". White Fused Alumina fine powder is made of aluminum alumina or industrial alumina, which is made of high-temperature melting in the arc furnace. Al2O3 ≥98.5%, white block, showing the pores of 6%-10%, the main crystal phase is α-al2O3 , The crystal is long and diamond -shaped, and often appears skeletal crystals. Due to the high purity of the raw material, chemical reactions are not occurred in the operation of the electric furnace, but the temperature and cooling speed of the melting liquid have a great impact on the structure of the block. In terms of homogeneity, it is important to obtain as much as possible.

Here White Fused Alumina section sand: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-12mm physical and chemical indicators: Al2O3 ≥ 99% NA2O ≤ 0.5% CAO ≤ 0.4% magnetic object ≤0.003% White Fused Alumina fine powder: 180 #-0, 200#-0, 320#-0 Physical and chemical indicators: Al2O3 ≥98.5% NA2O ≤ 0.5% CAO ≤0.5% magnetic object ≤ 0.003% Sometimes the particle size standards of White Fused Alumina can be processed according to different needs of customer.
