The characteristics of our graphite blocks:
1. low electric resistance
2. high temperature resistance
3. good electric and thermal conductivity
4. high oxidation resistance
5. greater resistance to thermal and mechanical shock
6. high mechanical strength and machining accuracy
7. homogeneous structure
8. hard surface and good flexural strength
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.
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
