graphite brick and carbon brick are widely used as the lining material in various of high temperature furnace or chemical equipment. In many chemical processes, the equipment and reaction vessels must be protected against the acidic and caustic materials used in the processes. The linings made from ceramic or synthetic plastic type materials are often unsuitable, since they may not withstand chemical attack, high temperature or sudden temperature changes. Alkaline solutions and hydrofluoric acid are of great importance in chemical technology, but they rapidly destroy equipment linings not made of carbon containing materials.

The application of graphite block:
1. Used for producing graphite crucible, moulds, rotor and shaft, ect.
2. Used as the materials for the furnaces
3. Used as various machining parts in the acid, alkaline, or corrosion environment
4. Used for the graphite electrode making
5. Used to manufacture seals and bearings in pumps, motors and turbines
The forming process of our graphite blocks:
Our graphite block is made from superior petroleum coke, and manufactured through crushing, calcining, medium crushing, milling,
screening, dosing, kneading, forming, baking, impregnation, graphitization, machining, and inspection. Every step procedure is
strictly controlled by our engineers to ensure the product quality.
Graphite brick
1. Good electrical conductivity:
good lubricity, high temperature resistance, good electrical conductivity, high mechanical strength
2. Support customization:
A large number of quasi specifications in stock, stable product performance, long practical life, can be customized
3. Stable performance: carefully select raw materials for strict testing of products and refuse to shoddy
