Sintering Mesh Belt Conveyor Furnace

Lindberg® sintering conveyors are designed for a variety of heat-treating processes with or without atmosphere. They are furnished with brick refractory or molded ceramic fiber insulation, that is lighter, has less thermal mass, and lower thermal conductivity than conventional brick refractory. A variety of sizes and belt widths are available. Temperature range to 2100°F.

An automatic electric atmosphere system assures positive ignition of combustible process gases. Safety back up system includes a secondary igniter, nitrogen safety purge, and audio and visual alarms. An automatic inert gas purge of the muffle is provided both before the introduction of a combustible atmosphere and at the conclusion of the process cycle. Excess temperature safety system, including audio and visual alarms, guards against temperature conditions.

Flame curtains at each muffle door can be provided in place of nitrogen purge chamber. Panel interlock power switch and circuit breaker allows control panel door to open only when power is off.
