Roller Continuous Furnace # 1333

Roller furnace for heat treatment of steel coils in nitrogen atmosphere. The furnace performs heating and controlled cooling of coils held by specifically designed supports. The load is composed on a platform in front of the furnace door where the coil supports are loaded/unloaded. Heating is via radiant tubes with self-recuperative gas burners. Cooling is via cold air pumped into the radiant tubes and additional tubes used for cooling only are installed below the load. High speed air circulation, optimized by CFD, assures high temperature uniformity. Air is recirculated in a chamber created between the insulated external panels and an internal stainless-steel panel. A fan mounted on the furnace floor extracts the air from the load and generates a turbulent flow in the recirculation chamber where air is heated by the heating elements. Hot air flows back into the chamber from below the parts being treated and transfers the heat to the load. Recirculation fans and heating elements are mounted on plugs for easy maintenance.
