The invention belongs to the field of
tungsten-
molybdenum processing equipment, and particularly relates to a box-type vacuum and
atmosphere medium-frequency induction
sintering furnace. The box-type vacuum and
atmosphere medium-frequency induction
sintering furnace comprises a furnace shell, a furnace core
assembly positioned in the furnace shell, a vacuum
system connected with the furnace shell, a water
path system and a gas
path system, and the furnace core
assembly is of a cuboid box type structure; a heating body, a
refractory material and an
induction coil are sequentially arranged around the cuboid box-shaped structure from inside to outside, and a furnace top cover is arranged at the top of the cuboid box-shaped structure; and the vacuum
system is used for providing a vacuum environment for the interior of the furnace shell, the water
path system is used for providing cooling water for the furnace shell, and the gas path
system is used for providing working gas for the furnace shell. By the adoption of a
hearth of the box type structure, a sintered
tungsten-
molybdenum plate blank product is horizontally placed on a discharging bottom support, bending deformation of the sintered material is improved to the maximum extent, the straightening and leveling procedures of the
tungsten-
molybdenum product are reduced, and the production cost is reduced.
