Lucifer Furnace’s high-temperature GT furnace, model HS3GT, is capable of heating to 2,450°F under inert atmosphere, with an SCR power supply for well-regulated voltage and current output. The single-chamber box unit, with a working dimension of 12" × 12" × 24", is heated with silicon carbide glowbar elements mounted across the roof and beneath the heavy-duty silicon carbide hearth plate for uniform heating.
To minimize heat loss and maximize durability in thermal-shock conditions, the furnace features 4" of premium-grade, multilayered, ceramic fiber insulation and 2.5" of mineral-wool insulation backup.
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 hot face away from the operator at all times and is specially designed to withstand warping and distortion, the company says. 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.
