Reheating Furnace of Rolling Mill

Reheating Furnace for Rolling Mills
A Reheating Furnace is an essential thermal processing equipment used in the steel rolling industry to heat billets, slabs, or blooms to the rolling temperature, typically between 1000°C to 1300°C. It ensures optimal metal plasticity and reduces rolling resistance, thereby improving product quality and rolling efficiency. Our reheating furnaces are widely applied in bar mills, wire rod mills, section steel production lines, and plate rolling lines. We offer push-type, walking beam, and walking hearth furnace configurations tailored to customer-specific production needs.
