Furnace Charge Drying and Preheating Systems
Preheating removes moisture from scrap material prior to furnace charging and helps reduce this danger. 2. Increased Melt Rate. With preheating steel, a large part of the melt energy is introduced into the metal outside of the electric arc furnace. Preheating scrap material to 1200° F can increase induction furnace melt rates by as much as 20%.
