Embodiment Construction

[0013] It is known from Fig. 1 that it is a perspective view of the present embodiment. It is composed of a furnace shell 1, a furnace and an electric furnace control system. The inner lining of the furnace is a fiber module 4, which is fixed with ceramic nails 5 anchors along the circumference of the fiber module 4. The high-temperature resistance band 8 has ceramic nails 5 to fix the brim of the hat 10, after preventing the reactor iron sheet from falling off on the resistance band.

[0014] Known by Fig. 2, it is a sectional view of the present invention. The high-temperature-resistant fiber module 4 is a white high-temperature-resistant fiber module. The module is extruded to make a hollow cylinder-shaped furnace lining. The furnace lining is fixed on the furnace frame welded by channel steel 6 and flat iron 3, and fixed by anchors. it is good. The conductive rod 7 is connected outside the furnace body, and the bottom of the furnace shell 1 has a refractory brick 9.

Abstract

The invention relates to a vacuum heating furnace for smelting spongy titanium and spongy zirconium, which comprises a furnace shell (1), a hearth and an electric furnace control system, wherein a lining of the hearth is a fiber module (4). The vacuum heating furnace for smelting spongy titanium and spongy zirconium is characterized in that high-temperature resistance belts (8) are fixed along the circumference of the fiber module (4) by anchoring elements of ceramic nails (5), and ceramic nail fixed nuts (10) are arranged among the resistance belts so as to prevent an iron sheet dropping offa reaction vessel from dropping on the resistance belts. The structure has favorable heat preservation effect and rapid heating for warming and switching off for cooling, greatly reduces the temperature of the outer wall of the furnace, is more suitable for the production technology for smelting spongy titanium and spongy zirconium, achieves accurate temperature control, effectively controls power and saves energy by more than 20 percent.
