PRODUCT SHOWCASE: Lucifer Furnaces Equips ETREMA Products With HS3-GT Furnace

ETREMA Products, Inc., the world's leading supplier of magnetostrictive materials, such as Terfenol-D®, has recently installed a Lucifer Furnaces High Temperature GT furnace in its Ames, Iowa facility. Model HS3GT is capable of heating to 2450°F under inert atmosphere, with an SCR power supply for well regulated voltage and current output.  This single chamber box unit, with a working dimension of 12”H x 12”W x 24”L, is heated with silicon carbide glowbar elements mounted across the roof and beneath the heavy-duty silicon carbide hearth plate for uniform heating.

Four inches of premium grade multilayered ceramic fiber insulation, for minimal heat loss and maximum durability in thermal shock conditions, and 2 ½ inches of mineral wool insulation backup line the work area. The outer shell is fabricated from heavy gauge sheet steel reinforced and continuously welded for operation with a positive flow of inert atmosphere. The double pivot horizontal swing door keeps the hotface away from the operator at all times and is specially designed to withstand warping and distortion. A ceramic fiber gasket around the door perimeter and swing bolts with T handles compresses the door against the furnace faceplate. Accessories include an over temperature safety system with a high limit controller and an inert atmosphere flow meter.  ETREMA plans to use the furnace in process development work for ETREMA’s Galfenol alloy system. Galfenol is a new magnetostrictive material that offers the exciting combination of excellent magnetostrictive and mechanical properties. ETREMA also offers engineering services focused on magnetostrictive device development for a variety of industries and applications.
