prefabricated magnesia refractory brick for heavy non-ferrous metals industry
The refractory castable precast blocks at the top of the open mode anode baking furnace’s flame tube is the main component of the furnace’s surface. In the past as the density of the preformed bricks is high, and therefore has very high thermal conductivity. The measured data show that the surface temperature of the precast blocks at the top of flame tube could be up to 200℃ and above, directly led to high temperature in furnace surface, heavy heat loss and severe operating conditions. Thus, we investigated and developed the brand-new composite light casting layers in the upper surface of the prefabricated furnace surface bricks based on the original refractory castable precast blocks. This kind of new material is ensured to greatly reduce the surface temperature of the furnace surface bricks based on the basis of the original material performance(The minimum temperature of furnace surface could be less than 60℃), the heat loss can be reduced and effectively improve the operating condition.

Company Profile
Refractory Industry is one of pillar industries in China Rare-Earth Holding Group. Beneath its 100% holding, there are two subsidiaries: Yixing Xinwei Leeshing Refractory Material Co., Ltd and Wuxi Xinwei Pan-Asia High-Temperature Ceramics Co., Ltd, professionally work on medium-to-high grade refractory material research, development, produce and project construction.
For many years, the company has followed the developping steps and trend of international and domestic refractory material markets closely, invest a huge sum of money to expand and reconstruct, explore and surmount in development constantly. Under support and help of numerous closed cooperative partner at home and abroad, under staff sincerely uniting and hard working, the company has already become one of the important bases that produce the medium-to-high grade refractory material at home
Production Capacity
The company can produce the refractory material products of 178 product brands under eight major series, the annual production capacity is up to 100,000 tons, among them, 60,000 tons of fired products medium-to-high gradly, 20,000 tons of unfired products, 20,000 tons of unshaped refractory materials. The company enjoys the power to engage in import and export trade on its own account, the products find a good sale in Japan, Korea S., Russia, Australia, U.S.A. etc. . Company refractory exported account take advanced position in domestic!
Process Equipment
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.
