Electric Arc Furnaces
Electric Arc Furnaces harness a man-made 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 electrical insulation are critical to the operation of the furnace. From the electrical substation to the transformer wall to the delta closure to the bus tubes to the mast arm and into the electrodes, The Gund Company offers insulation components that meet your most demanding application requirements. Electrical insulation components supplied by The Gund Company have been engineered to perform in one of the most difficult environments on Earth. Our years of application experience coupled with our materials knowledge allow us to serve OEM’s, repair companies, and steel mills with an unparalleled level of service.
Electric Arc Furnaces channel the power of electricity to create and sustain 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 develop electrical insulation material solutions capable of handling the unique combination of thermal, electrical, and mechanical requirements of the application.
With internal temperatures as high as 3,000 °C (5,432 °F), the components of electrical arc furnaces endure some of the most demanding operating environments in the electrical industry. For over three decades, The Gund Company has specialized in electric arc furnace insulation components. 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. And when shutdowns happen, our engineering expertise can bring solutions on-the-fly to help melt shops get back in production.

Induction Furnaces
An induction furnace uses an electrically induced magnetic field to heat metal to its melting point for further processing. The two most common types of induction furnaces are coreless and channel furnaces with coreless furnaces being the most common. Induction coils pass electrical current through insulated copper turns shaped much 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 each major OEM 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 the 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 & Learn event at your facility. Our presentation will focus on insulation material engineering for the most demanding metals processing applications.
