INSIDE A CONTINUOUS SINTERING FURNACE Thomas Philips, John J. Dwyer, Jr. and Zbigniew Zureck ABSTRACT . The quality of the atmosphere inside a sintering furnace plays a key role in the final properties of the sintered part. Properties such as the hardness, ductility, dimensions, carbon content, microstructure

Furnace atmosphere is recirculated across a heat exchanger and impinged on parts as they emerge from the sintering furnace. Accelerated Cooling The length of the water jacketed cooling section can be reduced by the use of an accelerated cooling section placed at the rear of the furnace where the cooling rate is slow.

Sintering green Fe-PM powder parts is a typical application. Modern stearate zones burn the pressing additives off. The parts are sintered under forming gas or endogas in the ceramic muffled sinter zone. Inbination with rapid cooling, the green parts can be heat treated in the sinter furnace.
