HEATING APPARATUS FOR ALLOYING GALVANIZED STRIP

摘要

PURPOSE: A heating apparatus for alloying galvanized strip is provided to accurately measure a temperature of the steel sheet within a heating furnace, and thus to control its temperature at an appropriate value. CONSTITUTION: The heating apparatus for alloying galvanized strip consists of an impedance measuring system(12) for measuring a temperature of the steel sheet inside a heating furnace(4) from an impedance of the heating furnace, an impedance control system(13) for feedback controlling an impedance of a high frequency power source(11) using the measured temperature, and the high frequency power source for adjusting an amount of heating.
