HIGH-FREQUENCY INDUCTION HEATING METHOD USING A WATER-EXCLUSIVE COIL, WHICH IS MADE FROM GRAPHITE WITH HIGH THERMAL CONDUCTIVITY AND ELECTRIC CONDUCTIVITY TO OBTAIN LARGE INDUCTION HEATING EFFECTS, AND A HIGH-FREQUENCY INDUCTION FURNACE USING THE SAME

摘要

PURPOSE: A high-frequency induction heating method using a water-exclusive coil and a high-frequency induction furnace using the same are provided to prevent an explosion accident resulting from the leakage of cooling water by using a graphite coil as a high-frequency induction coil to eliminate the need of cooling water.;CONSTITUTION: A high-frequency induction furnace using a water-exclusive coil comprises a crucible(14), a high-frequency induction coil, and a high-frequency generator(13). The crucible is arranged in a vacuum chamber(10) to melt or cast a material. The high-frequency induction coil is formed in a spiral form outside the crucible and provides high-frequency induction current to heat the crucible with induced heat. The high-frequency generator supplies high-frequency current to the high-frequency induction coil. The high-frequency induction coil is a graphite coil(11) made from graphite.;COPYRIGHT KIPO 2013
