Model RD7-KHE24 Furnace

February 12, 2012

Lucifer Furnaces Inc. recently delivered a single chamber bench model box furnace to Power Plant Services, an ISO 9001certified provider of parts and repairs for the power generation and steel mill industries. Model RD7-KHE24 is part of the Red Devil Series of furnaces built with economy, energy efficiency and ease of use in mind. The 12" H x 14" W x 24" L heating chamber is lined with 4.5" of multilayer firebrick and mineral wool insulation.

Heating elements on the side walls provide 7 KW of power capable of heating to 2200°F. Heating element coils are equally spaced and fully supported in easy-to-replace element holders to provide uniform heat and long life. Element lead wires are insulated by ceramic tubes through the rear wall brick for protection from electrical shorting and contamination.

The box furnace frame is manufactured with heavy gauge sheet steel reinforced and welded to form a rigid unit with a heavy gauge front faceplace designed to withstand warping and distortion from the chamber heat. A rear mounted type K thermocouple assembly is located through the rear wall of the chamber for rapid sensing of the chamber heat.

The Red Devil bench model comes standard with a horizontal swing door insulated with multilayered ceramic fiber insulation with heavy duty hinges and a cam lock to insure a tight seal as well as a safety micro-switch to automatically shut off power to the heating elements whenever the door is opened. The chamber of the unit is fitted with a ceramic hearth plate to support a workload of 25 lbs. per square foot of hearth area. A digital time proportioning temperature controller and all other instrumentation are mounted in a separate control panel on the side of the furnace away from the heat and loading of the chamber.

    computer-aided manufacturing ( CAM)

    Use of computers to control machining and manufacturing processes.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
