Glass Kiln Furnace Refractory Fire Fused Cast Azs Zircon Corundum kiln refractory brick
Product Description
Fused Cast AZS block as an important role used in Glass Furnace is made of pure alumina powder and zircon sand and is composed of three main chemical components of Al2O3, ZrO2 and SiO2,most widely used materials both in glass contact and superstructure of glass melting furnaces. The products are made of high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity,excelerosion resistance and used for linings of furnace in glass industries.
Features
Dense micro structure
Strong resistance for high temperature and glass liquid
Good thermal shock resistance
High compression resistance
Wear and slag erosion resistance
Shapes & Sizes Of Fused Cast AZS Block

| 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. It is the first Chinese private enterprise which
engages in the manufacture of rare earth and refractory products
listing outside the Chinese mainland.
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.
The Group has a research and development centre that focus on improving existing products and developing new products. Building and maintaining relationships with clients and exploring new businesses are the responsibility of its talented sales and marketing department. Concerning the environmental protection as well as the market needs, the Group will continue to develop environmental friendly and high value-added products. |

CRE began its business in 1987 in the city of Yixing, Jiangsu
Province, the PRC. Commencing operations as a rare earth separating
factory, it has grown rapidly to become a recognised rare earth and
refractory products manufacturer. 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.
