A Rolling Mill Furnace is an industrial furnace used to heat metal billets, slabs, or blooms before they enter rolling mills, ensuring uniform temperature, improved workability, and reduced rolling forces. Operating typically up to 1200–1300°C, it is widely used in steel and alloy rolling for hot rolling and reheating prior to forging. These furnaces can be gas-fired, oil-fired, or electric (resistance or induction), with refractory brick or ceramic fiber insulation and, for electric types, Ni-Cr or Kanthal heating elements. Modern designs often feature regenerative burners, continuous operation, and automated temperature control, providing energy efficiency, consistent metal quality, and reduced wear on rolling equipment.
