Directed Bonded Magnesite-Chrome kiln refractory Brick for glass furnace lining
Refractory Material for Glass Industry
The products made by No. 1 branch of our company mainly serve line of building material, and we have devoted ourselves to developing and researching refractory material for large float-type glass-melting kilns in recent years, and this company is a maker appointed by National Building Material Bureau, Hangzhou Designing Institute, Qinhuangdao Designing Institute and Bengbu Designing Institute. In recent years, we have made great progress in the aspect of development and application, for instance, a regenerator developed by us won us Scientific Progress Award of Shanghai municipality and Light-Industry Scientific Progress Award Of China, and the Checker bricks won us The Third-Class Award for Excellent Products of Shanghai Municipality, and the high-grade electrocast rebonded magnesia series, the zircon series, the magnesia-alumina spinel brick series and the unshaped refractory material series were appointed as recommendable products by China Building Material Industry Association. And the refractory material for glass melting kilns were determined as the Key Scientific Research Project in National 8th five-year plan.
Besides the 8 series of products, we have also developed many specific products, which can be applied in large float-type glass melting kilns. Up to now, we have provided series of complete sets of high-grade magnesia, magnesia-chrome, zircon, AZS products for walls of regenerators of almost 20 domestic large float-type glass assembly lines and more than 100 glass melting kilns, and they all can meet the design demand in the aspect of variety and quality, and have the features of high-temperature resistance, corrosion-resistance and high thermal stability, etc.
As a result, they also won us praises from our users. And the products used in the regenerators all can serve for more than 5 years.

| 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. |
