Oxided Bonded Fire Brick Silicon Carbide Block Refractory Bricks for Electric Furnace Lining
Refractory material for Metallurgical industry
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 kurasaki share- issuing company, 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 New Japan, NKK, kimizu, aoida and nisingkou steel Co.s In recent years, we had furthered our technological cooperation with kurasaki stock-sharing company.
Unnumbered proofs and experiments have been done during the course of from raw material selection to finish of production. And quite a lot work force, goods and materials and financial resources have been spent in optimizing our technological scheme and technical line, and a complete set of production technique have been drawn up of electrical-melted re-bonded/semi-rebonded magnesia-chrome bricks, and those electrical-melted re-bonded magnesia-chrome, Aluminized and Carbonized silicon-carbon bricks sintered under 1850°C have been exported to New Japan steel Co., Ltd. and YAHADA steel works under NKK steel pipe Co., Ltd. Thus a new way to export refractory materials made in China has been opened up, and the ground for refractory material optimization in China established Our 8 series of refractory materials could satisfy not only general demands from steel companies, but also specific ones from metallurgical industry.
