Extruded graphite block for exothermic welding
Technical Characteristic As the material of exothermic welding mold, graphite has the following characteristics: 1) High temperature resistance: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even if burned by ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases with increasing temperature. At 2000°C, the strength of graphite doubles. The temperature of the chemical r... -
