Bell Furnaces Electric Bell Furnace The Rod Overbend (RO) Element Bell Furnaces give you flexible, efficient performance in a variety of heat-treating applications. The fast-heating rate, • Annealing • Austempering • Carbonitriding • Carburizing • Hardening • Martempering • Preheating • Solution Treating • Stress Relieving • Tempering •Normalizing heavy-load capacity and reliable operation help you achieve fast turnaround and high productivity. The furnace is very simple and economical to operate and is available in a wide range of sizes. The RO bell applications range up to 2150°F, with endothermic, exothermic or nitrogen atmospheres. This furnace enables you to anneal, austemper, braze, carbonitride, carburize, harden, martemper, solution treat, stress relieve and normalize efficiently and economically. TPS can help you evaluate your needs for reducing process emissions whether it's providing an afterburner for your existing system or supplying an afterburner with a new Lindberg furnace.
