ELECTRIC ARC FURNACES, LADLE METALLURGY FURNACES & SECONDARY CIRCUITS
Electric Arc Furnaces harness an artificial lightning bolt to melt scrap metal, most commonly steel.
Due to the tremendous electric power required to operate an arc furnace, the function and performance of the electrical insulation are critical for optimal furnace operation. The Gund Company offers insulation components that meet your most demanding application requirements, including the substation, transformer vault, secondary circuits, electrode holder arm, and bottom anode (DC). Electrical insulation components supplied by The Gund Company have been engineered to perform in one of the most challenging environments on Earth. Our years of application experience, coupled with our materials knowledge, allow us to serve OEMs, repair companies, and steel mills with unparalleled service.
Electric Arc Furnaces channel the power of electricity to create and sustain an electrical arc capable of melting 100 tons of scrap steel in forty-five minutes. To harness and control this type of energy, furnace design engineers work with The Gund Company to manufacture electrical insulation material solutions capable of handling the application’s unique combination of thermal, electrical, and mechanical requirements.
With internal temperatures as high as 3,000°C (5,432°F), the components of the electric arc furnaces endure some of the most demanding operating environments in the electrical industry. The Gund Company has specialized in electric arc furnace insulation components for over three decades. Whether helping with material selection and component design options for the OEM or developing a proactive “spares” program for the melt shops, we understand what it takes to keep the furnace making steel. During shutdowns, our engineering expertise can bring solutions on-the-fly to help melt shops get back in production.

INDUCTION FURNACES
Use an electrically-induced magnetic field to heat metal to its melting point for further processing.
The two most common induction furnaces are coreless and channel furnaces, with coreless furnaces being the most common. Induction coils pass electrical current through insulated copper turns shaped like an enormous spring. The copper turns must be electrically insulated from each other to prevent short circuits in the coil. The Gund Company custom fabricates components for all major OEMs and related repair companies of induction heating equipment in North America.
In this application, the electrical insulation materials fabricated by The Gund Company perform a critical role. Our application experience and materials knowledge allow our customers to obtain optimal performance from their equipment. The Gund Company manufactures and fabricates a complete line of insulating components for induction furnaces, electric heating applications, and related power supply equipment.
Our long history of developing electrical insulation component solutions for these high-temperature applications provides our customers with a knowledge source of responsive options for spare parts to keep them in operation. To learn more about our induction furnace insulation components, request a lunch-and-learn event at your facility. Our presentation will focus on insulation materials engineering for the most demanding metal processing applications.
With our years of application experience, coupled with our materials knowledge, The Gund Company is here to serve OEMs, repair companies, and foundries with unparalleled service.
