Slip Plane Characteristics of Mica Roll
Induction furnaces provide an energy efficient solution to processing for the foundry and steel industry. The induction heating of metal involves applying heat to a coil of copper wire that surrounds a non-conductive crucible, containing the material to be melted down.
An alternating current runs through the copper wire coil, which creates a rapidly reversing magnetic field that can penetrate the metal. This penetration then induces circular electric currents inside the metal, eventually breaking down its resistance.
The advantage of the induction process for heating metal is that it avoids contamination of the material through use of any other external heat source, such as burning fuel.
However, due to the intense heat involved, the crucible lining must be able to withstand high temperatures, to maintain consistency and productivity. This is where the slip plane characteristics of mica roll as a furnace lining are so critical to foundry processes.
