High Density High Strength High performance Self Flowing corundum Castable

Insulation Castable
According different working temperature the bond material of insulation castable can be perlite, vermiculite,
light weight clay.light weight mullite, bubble alumina. We can supply insulation castable from 800ºC-1700ºC density from 0.8-1.5g/cm3.

Refractory castable:
Refractory castable is mixed by high quality raw materials such as bauxite, flint clay, silica powder,
α-alumina powder as micro powder, refractory cement as binder.
Also some additive to make better performance. Formulas are changed according to different applications.
Our refractory castable are using in steel industry, boiler furnaces, incinerators and other industrial furnaces.

Feature:
* Excellent abrasion resistance
* Excellent high temperature resistance
* Excellent crushing strength
* Anti corrode

Application
* Incinerators
* Aluminium industry
* Cement industrial
* Steel industrial
* Boiler
* Pizza oven

Yixing Xinwei Leeshing Refractory Material Co., Ltd

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.

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.

The refractory materials produced by No.2 branch of our company mainly serve metallurgical industry at home and abroad. Since the company was set up, we have established technologically cooperative relations with Japan Krosaki Harima Corp., and mastered advanced technology about refractory material production, and we have got a great achievement in improving the quality and developing new varieties of refractory materials ,which are used in refining furnaces, pouring ladle mixers, blast-furnaces, hot-air furnaces, large lime kilns, and non-ferrous metallurgy, and products, which are made in China rather than imported, have met requirement in designing and using. For instance, we provided a series of deoxided vacuum electrical-smelted re-integrated magnesia-chrome bricks for the outside of RH furnace for Baoshan steel Co., Wuhan steel Co., Taiyuan steel Co., Ma' anshan steel Co... We supplied series of directly bonded magnesia-chrome, semi-reintegrated chrome-magnesita, electrical-smelted re-bonded magnesia-chrome cast materials ,etc. for domestic large non-ferrous metal plants, such as Guixi metallurgical plant, Tongling non-ferrous metal Co, Ltd. and Jinlong copper industry plant. And we furnished low-creep mullite series products,pre-masonry cordierite-mullite bricks, sillimanite ones, micro-porous sintered Alumina-carbon ones and cast materials for ladle body, tapping landers, slaglanders, branch landers and pre-fabricated parts for Baoshan steel Co., Ma anshan steel Co., No. 1 branch of Shanghai steel Co. and ZIMBABWE Co. which is assisted by Beijing, Jiuquan steel Co., etc. And we provided NKK AL203-SiC-C products in use for torpedo cars for Japan Nippon Steel, Japan NKK, Japan Kimitsu, Japan Oita, Japan Nisshin.

In recent years, it has cooperated with Japan's Kurosaki Harima Co., Ltd. in deep technical cooperation, and has hired Japanese experts to serve as chief engineers in the company all the year round. From raw material selection to finished product production to product packaging and transportation, all links are produced and controlled according to international standards. The company's technical solutions and process lines have been optimized, and a complete set of electrofusion recombination and semi-recombination magnesia-chrome brick production processes have been developed. , high-quality high-purity magnesia bricks and non-fired aluminum silicon carbide carbon bricks and other products have entered a large number of "Nippon Steel Co., Ltd., Steel Pipe Co., Ltd. Yawata, and Hiroko Steel Works, creating a new road for my country's refractory exports and for my country's The optimization of refractory resources has laid a certain foundation.

In addition to meeting the general needs of steel mills, the eight series of refractory products produced by our company (see the company's general sample) have also developed many special products to meet the special requirements of the metallurgical industry, and matched our leading products to provide The user implements the EPC to meet the user's needs.
