Forming Process Of Graphite Blocks
Gufan 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.
Characteristics
- Low electric resistance
- High temperature resistance
- Good electric and thermal conductivity
- High oxidation resistance
- Greater resistance to thermal and mechanical shock
- High mechanical strength and machining accuracy
- Homogeneous structure
- Hard surface and good flexural strength
Applications
