Roller Hearth Furnaces

Abbott Furnace Company custom designs and manufactures roller hearth furnaces for a variety of applications, particularly those requiring heavy loads and high-volume capacity, long part length, and reversible or oscillating conveyance drives. Abbott’s emphasis on superior control of temperature and atmosphere management provides uniform and consistent results for these high production furnace systems.

Roller hearth furnaces are applied for a variety of common heat treatments, such as annealing, normalizing, stress relief, hardening, and tempering, as well as reheat and brazing, but are particularly suitable for multi-step processes with multiple in-line process chambers with isolation doors and purge chambers.
