Induction heating steel with 60 cycles

摘要

A NEW field for the application of induction heating has developed. High-frequency heating of metal is already accepted as an indispensable tool of industry for surface heating and for through-heating small pieces. The steel industry is now turning its attention to lower frequencies for heating large sections to forging temperatures, approximately 2200 degrees Fahrenheit (F). The heating of steel for forming is a large part of steel manufacture. The methods used over the years have gone through an evolution. With the development of high-speed rolling and forming techniques, a need for faster heating methods has arisen. Low-frequency induction heating seems to provide a good answer to this need.
