Abstract
The utility model relates to a vacuum nitriding furnace and belongs to the field of chemical heat treatment mechanical equipment. The vacuum nitriding furnace is formed by a furnace body, a base and a cathode disk. The furnace body is movably arranged on the base. The cathode disk is arranged at the center position of the base. A vacuumizing device is arranged on the base below the cathode disk. A heat screen is arranged in the furnace body. The top of the furnace body is respectively provided with an ammonia gas inlet and a cooling circulating water outlet. A cooling circulating water inlet is arranged at the lower end of the furnace body. A plurality of observation windows are arranged on the periphery of the furnace body. The furnace body is of an interlayer structure. A cooling water circulating cavity passage is arranged in the interlayer. The vacuum nitriding furnace has a reasonable and simple structure. A good heat insulation effect is achieved by the heat screen and a heat insulation bottom screen. Due to the cooling water circulating cavity passage arranged in the interlayer, cooling water orderly enters and exits and the energy consumption is reduced. Compared with the prior art, the vacuum nitriding furnace solves the problems of poor heat insulation effect, difficulty in temperature control and high energy consumption, the work efficiency is improved, and the mechanical performance of the surface of a processed workpiece meets the design requirement.
