Dry extinguished coke tank lining

详情

Hot bright coke extinguished without water (dry extinguished), the quality of coke produced by this method is good and high efficiency, but the material need high requirement cause that the coke tank linings must endure high temperature shock. Bao steel introduced this coke production system from Japan with high price. The coke tank linings made by some factories in china have cracked into pieces, cut off the transport belt which worth million yuan. Among the lining manufacture enterprises, we win the quality champion in ***7. Dry extinguished coke manufacturers, such as Bao steel shanghai gas company, Jinan Steel Plant, their tank lining are all delivered by us. Our market covering is **0%.
