Walking beam furnaces for billet preheating — Kanthal®
However the fossil-fuel-based heating typically used in walking beam furnaces is inefficient consuming large amounts of energy and emitting high volumes of CO2. By electrifying the heating process through Kanthal s Globar ® and Kanthal ® Super heating elements steel producers can achieve much higher thermal efficiency and potentially reduce CO 2 emissions to zero.
