Other Materials of Construction

High coefficient of thermal expansion; swells significantly under heat Flows (creeps) under relatively low loads, even at room temperature (usually stated as "cold flow") Can be readily blended with other materials to improve its features and performance characteristics

Graphite Electrodes

Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power.

Selection of raw materials for Al2O3

Graphite material has high thermal stability, the sublimation temperature is 3800, it is easy to reach saturation in molten iron, so graphite has the advantage of resisting molten iron corrosion. Commonly used graphite materials include amorphous graphite, artificial graphite, spherical graphite and flake graphite.
