    Types of Heat-Treating Furnaces

    Published: 1990
    Authors: John W. Smith, Holcroft, A Division of Thermo Process Systems Inc.

    FURNACES commonly used in heat treating are classified in two broad categories, batch furnaces and continuous furnaces. In batch furnaces, workpieces normally are manually loaded and unloaded into and out of the furnace chamber. A continuous furnace has an automatic conveying system that provides a constant work load through the unit.

    Salt Bath Heat-Treating Equipment

    Published: 1990
    Authors: W. James Laird, Jr., The Metal Works Industrial Furnaces, Inc.

    HEAT TREATERS can no longer use heat-treating methods that are only uniform, quick, efficient, and economical. They must also be environmentally responsible. Salt bath heat-treating methods are uniform, quick, efficient, economical, and environmentally responsible.

    Fluidized-Bed Heat-Treating Equipment

    Published: 1990
    Authors: Revised by Robert F. Sagon-King, Can-Eng Ltd

    FLUIDIZED-BED TECHNIQUES are not new to the metalworking industry. A 19th century American patent describes the roasting of minerals under fluidized-bed conditions. Other established applications include potter's clay and miner's hydraulic slurries. Systems of fluidized solid particles, such as quicksand, occur in nature.

    Heat Treating

    Published: March 01, 2002
    Authors: Matthew J. Donachie and Stephen J. Donachie

    Why Heat Treat? All superalloys, whether precipitation hardened or not, generally require the application of heat for some period of time for purposes of preparing solid material for a subsequent processing step (ingot cogging, component forging, etc.).

    Energy-Efficient Heat-Treating Furnace Design and Operation

    Published: 1990
    Authors: S. Lampman, ASM International

    ENERGY EFFICIENCY AND COST of heat-treating operations are related concerns that are substantially affected by the method of converting stored energy into molecular kinetic energy (temperature) of the workpiece(s).
