Many factors come into play during the vacuum sintering process, from the size and materials used in the furnace hot zone to whether debinding and sintering processes are combined in a single unit.

Vacuum sintering is one of the unsung heroes of industrial metallurgy. In this crucial process, materials are heated in a vacuum environment until they are almost at the point of melting.

Brazing furnaces today often contain a lot of very heavy fixturing materials in their brazing chambers. This “fixturing” includes all the heavy-metal structures in the furnace hot zone (e.g., grates, trays, racks, baskets, etc.).

This article will highlight advanced furnace design features, illustrating both yearly power savings and possible power-company rebates.

In a furnace, the hot zone is crucial for the temperature distribution, cleanliness of operations and energy consumption of high-temperature processes.
