High temperature resistant carbon brick

High temperature resistant carbon brick

Item No.: BS
The material of High temperature resistant carbon brick has higher purity. The special technology of high temperature bake and graphitizing are used into the producing.
Description Application
    After several yearsJ scientific research, aiming at changing the weakness of bad function in some aspects of the original product in extreme abominable environment, we develops High temperature resistant carbon brick (block). The material of the product has higher purity. The special technology of high temperature bake and graphitizing are used into the producing. It makes the products have more superiority than other ordinary products in endurance high temperature, abrasion resistant and strength.
