Product Details

Factory Price Heat Resistance Fire Resistant Alumina Block kiln Refractory Bricks For industry Furnace

 

Material and Technique

 

Best price refractory magnesia alumina spinel bricks for cement rotary kiln transition zone are produced by using high purity sintered magnesia and sintered spinel as main materials, reasonable gradation, being high pressure pressed and sintered in high temperature.

 

Properties

 

Magnesia alumina spinel bricks for cement rotary kiln are characterized by high melting temperature, low thermal expansion, good thermal shock resistance, good anti-stripping capacity, high temperature strength and volume stability.

 

Application

 

Refractory magnesia alumina spinel bricks are industry-specialized products for working linings of high-temperature zone of large and medium sized cement rotary kiln.

 

 
China Rare Earth Holdings Limited ("CRE") (formerly known as Yixing Xinwei Holdings Limited) is one of the leading and well-respected rare earth and refractory products manufacturers in the Peoples' Republic of China ("PRC"). The Group has been listed on The Stock Exchange of Hong Kong Limited since 15 October 1999.

The Group successfully obtained ISO9002 quality certification in January 1999. Its annual production capacity reaches 6,500 tonnes (REO) rare earth products and 100,000 tonnes refractory products. Fluorescent materials, polishing agents and high temperature ceramics are other major product lines of the Group.

 

The Group operates a rare earth separating factory and a refractory production factory. The rare earth separating factory comprises a smelting rare earth products workshop, several rare earth extraction lines and many cutting edge equipment while the refractory production factory embraces a refractory products workshop with several high-temperature tunnel kilns, light tonnage brick pressers and pre-moulded production lines. The Group believes that the high quality production facilities could produce the best rare earth and refractory products.

 

The industrial applications for rare earth products include high-tech electronic devices, computers, electronic motors, LCDs, DVDs, magnetic materials, magnetic memory chips, fibre optics, superconductors, mobile phone batteries, precision optics and many energy-saving environmental protection products. Refractory products are used extensively in heat-treatment facilities for petrochemical, steel metallurgy, non-ferrous metallurgy, glass, construction materials, chemical fertiliser and ceramics industries. Rare earth products of the Group are mainly exported to the United States of America, Japan, Europe and Korea, and its refractory products are mainly for domestic sales and export to Japan. Its client list includes names of international prominence, such as General Electric, Nippon Electric Glass, Siemens, Shin-et Chemical and Krosaki Harima, to name but a few.
