The cost advantages of eliminating secondary heat treat operations by using sinter-hardening powders have become evident. The growth of high hardenability powders for ferrous powder metal components necessitates some methodology for determining the appropriate furnace cooling rate and powder alloy that will accommodate sufficient hardening of different sized parts.

The heat treatment and sintering processes are dependent on time, temperature, and atmosphere. Precisely monitoring and controlling each of these parameters can result in higher productivity and improved part quality. The LINEMOD supervisory control and monitoring software addresses these issues by estimating the thermal and physical conditions inside a furnace using mathematical models.

LINEMOD is a state-of-the-art universal supervisory control system for monitoring, controlling, and diagnosing sintering furnaces. When applied to a furnace equipped with properly functioning process controls, LINEMOD will improve quality and consistency in heating while substantially lowering gas and fuel consumption. In addition, it can help determine furnace operating parameters for new products within the furnace design constraints.
