Dual-Chamber Furnace

The Series 8000 HSFT model is a dual-chamber, space-saving furnace for hardening and drawing high-speed steels and ceramics. A continuously welded furnace shell and gasketed door assembly provide a positive flow of atmosphere in the upper hardening chamber, which is rated for 2450°F. It is equipped with silicon-carbide heating elements mounted above and below the hearth for uniform temperature. An SCR power supply proportions the lowest power input required for each application and limits the amperage for a steady state control. The lower drawing chamber is complete with easy-to-replace wire-wound heating elements and a stainless steel liner and fan assembly to recirculate heat for uniform temperature. The lower chamber can operate at temperatures from 800-1600°F. Furnace sizes range from 12” x 12” x 12” to 24” x 24” x 36”.
