3,Characteristics of Fused Quartz Brick For Coke Oven:
1)The fused quartz bricks we supply are made of high purity fused quartz sand and fired in shuttle kiln at high temperature. The products are compact and of high strength. especially, their suddenly-changing temperature resistance is more than 30 times. The sulphide resistant acidic slag of the product has very good performance and has been applied in coke oven and glass furnace roof.
2)The product is white and packed with wooden pallets and waterproof film, which is convenient for sea and land transportation.
4,Product knowledge:
Coke oven cold repair is difficult, time-consuming and high cost. In order to meet the development needs of coke oven hot repair technology, our company has developed ZERO-EXPANSION silicon brick with superior performance, which can meet the requirements of rapid heating, and can be used after completion of masonry without long-time oven drying.The product basically has no size change, no cracking, no deformation, no contamination of impurities, and is safe and reliable for long-term use.
5.Good feedback of product use effect,the products have been exported to Pakistan, Russia, Australia
6.The manufacturer is a professional manufacturer and can provide complete product index test reports or third-party test reports.
