Inductotherm® IMZ® (Induction Multi-Zone) Bar, Bloom and Billet Heating Systems

Overview

Inductotherm® IMZ® (Induction Multi-Zone) Bar, Bloom and Billet Heating Systems provide mill operators with efficient, cost-effective technology for bringing bars, blooms and billets to optimum temperature prior to a forming, rolling or forging operation. The systems use high-efficiency, electro-magnetically shunted heating coils which are supplied with electrical energy by high-efficiency, solid-state power units. Features include temperature equalization for continuously cast billets; temperature control and consistency; a modular design for quick coil change to accommodate different sizes; level control to centralize all bar sizes in the coil opening; fully automated, PLC controlled material handling systems; and availability in frequencies between 60 and 10,000 hertz. These systems are used to reheat bars, blooms and billets before they move from the continuous caster to the rolling mill. They provide a rolling mill with a continuous supply of uniformly heated billets, bars and blooms at the proper temperature for subsequent forming, rolling or forging operations.
