The vacuum tungsten-wire furnace is a vertical vacuum resistance furnace that utilizes tungsten wire as its heating element. It is designed for the sintering of products—such as metal compounds, ceramics, and inorganic compounds—within a vacuum or a protective atmosphere, and can also be employed for the heat treatment of metallic materials. The vacuum tungsten-wire furnace features a vertical configuration and consists of a furnace lid, furnace body, furnace bottom, heating elements, a vacuum system, and an electrical control system.
