Fused Zircon Corundum Blocks For Glass Melting Furnace - China

Fused cast AZS block is also named as the fused zirconia corundum

blocks, it was made by the melting of mixtures of high purity of alumina

powder and zircon sand containing 65% of zirconia and 34% of silica in

the electric furnace.

The molten mixture in the furnace would be poured

into the mould already prepared, after the cooling and demould, the

machining process will be followed.

The final products is white colored

solid block.

Our products will use the industry alumina powder from local and the zircon sand from Australia as the raw materials, which will be made into the refractories containing the ZrO2 range from 33%---45%.

Our company’s innovation technique: Vacuum Casting Technology for Fused cast AZS blocks, already published

Our new production technique – the Vacuum Casting has been applied in the normal production, the relative paper: Vacuum Casting Technology for Fused Cast AZS Blocks--- an Energy—saving and Environment –friendly New Technology was published on the Germany magazine – Refractories World Forum, on the second phase in April, 2013.

Specifications were achieved by the testing to the specimens selected from the densified parts.

• Business Description: Henan Chief Way Industry Co., Ltd was founded in the late 1980s in
  
  Xinmi, Henan Province, China .
  
  With the support from its patented
  
  casting technology, the vacuum casting as well as the advantage of
  
  convenient and rich material resources, the company has created the
  
  famous trademark Chief Way in the field of fused casting industry
  
  of AZS blocks.
  
  Our company is the first joint stock enterprise in producing fused casting zircon corundum products in Henan Province.
  
  Our company owns capital asserts of 53 million RMB, now covers an area of 58, 000 ㎡ with 26, 100 ㎡ construction area and has 450 employees, including 65 technicians in different fields at all levels and 11 domestic and foreign experts and senior technicians.
  
  With complete quality management system, strong technological power, advanced inspection facilities.
  
  In 2001, our company passed ISO9002 certificate of international quality system.
  
  Our leading products are: fused cast AZS 33 , 36 and 41 blocks produced by oxidization process, zircon mullite products and unshaped refractories, others include insulating bricks and silica bricks.
  
  All these products are widely applied to glass and ceramic industry.
  
  Our annual production capacity is about 15, 000 tons .
  
  Due to the good quality and service, our products are very popular in domestic market as well as overseas market, such as Japan, Democratic People's Republic of Korea, Vietnam, Indonesia, Turkey and other countries.
  
  Over the years, the Chairman Mr Songfa Hou, has been leading the staff to reform and innovate, more than 10 patents and proprietary technology have been obtained of which the patent of oxygen blast method from the bottom of furnace has reached the international level.
