LARGE TEMPERING BATCH OVEN FOR GRINDING MACHINE MANUFACTURERS
This large unit has an 18 cu ft chamber with a vertical air flow pattern, wire-on-rod heating elements, and a roof-mounted stainless steel belt driven fan with a heavy duty motor that provides vertical airflow for uniform heat.
Lucifer Furnaces, Inc. (Warrington, PA) delivered a large tempering batch oven to a leading East Coast manufacturer of precision grinding equipment. Key features of this Series 4099 unit include a vertical air flow pattern and wire-on-rod heating elements. A roof mounted stainless steel belt driven fan with a heavy duty motor provides vertical airflow for uniform heat. Coil wound heating elements mounted on ceramic rods on all side walls provide rapid, energy efficient heat and are easy to replace.
A stainless steel liner serves to baffle the fan and elements so that air is circulated past the heating elements then upwards through the chamber. The 18 cu ft chamber is complete with cast alloy roller rails to accommodate a large, heavy load. The furnace is lined with 6½ in of multilayered lightweight insulating firebrick and mineral wool block for maximum heat storage and minimum heat loss. The furnace has a horizontal swing door with an adjustable latch to insure a firm brick-to-brick seal. Digital temperature controllers are mounted on a side panel. Powered with 42 kW, this heat treating tempering batch oven reaches 1400 deg F.
