Embodiment Construction

[0010] Such as figure 1 As shown, a vanadium-nitrogen alloy vacuum furnace includes a furnace body 1 and a furnace cover 2 movably connected thereto. The vacuum furnace is divided into a nitriding reaction chamber 4 and an oxygen barrier cooling chamber 5 separated by a tray 3. A heating mechanism 6 is arranged in the nitriding reaction chamber 4, and the nitriding reaction chamber 4 is connected to a nitrogen delivery pipe 7 to enter nitrogen gas. A hydraulic lifting mechanism 8 is arranged below the tray 3. On the side wall of the oxygen-isolated cooling chamber 5 A discharge port 9 and a material shifting rod 10 are provided, and a porous nitrogen diffuser pipe 11 penetrating through the oxygen-isolated cooling chamber 5 is provided at the bottom. The heating mechanism 6 includes an inner crucible and an outer intermediate frequency coil.

[0011] An insulating layer 12 is arranged inside the furnace body 1 .

Abstract

The invention discloses a vanadium-nitrogen alloy vacuum furnace comprising a furnace body and a furnace cover movably connected with the furnace body, wherein the furnace body includes a nitridation reaction chamber and an oxygen-insulation cooling chamber which are separated by a tray; the nitridation reaction chamber is internally provided with a heating mechanism, and a nitrogen delivering pipe is inserted into the nitridation reaction chamber for delivering nitrogen; a hydraulic lifting mechanism is arranged below the tray; the side wall of the oxygen-insulation cooling chamber is provided with a material outlet and a material stirring rod, and the bottom of the oxygen-insulation cooling chamber is provided with a porous nitrogen dispersing pipe communicated with the oxygen-insulation cooling chamber. In the invention, the nitridation reaction chamber and the oxygen-insulation cooling chamber which are separated by the tray are arranged on the vanadium-nitrogen alloy vacuum furnace, and when a reaction product is heated to be in a preset state by the heating mechanism arranged in the nitridation reaction chamber, the hydraulic lifting mechanism drives the tray to bring the product to the oxygen-insulation cooling chamber to be cooled and delivered out from the material outlet; and new raw materials to be heated are placed on the tray, thereby the continuous operation of producing and cooling at the same time is realized.

Description

technical field [0001] The invention belongs to the technical field of vacuum furnace equipment for metal smelting, in particular to a vanadium-nitrogen alloy vacuum furnace. Background technique [0002] At present, most of the equipment used by vanadium-nitrogen alloy manufacturers in my country is a strip furnace structure. Different heating methods are set in the furnace to realize different temperature zones in the furnace. The compounds of vanadium and iron are heated in a nitrogen environment. After reaching the reaction temperature and time process requirements, the production process is to cool with the furnace, and to cool naturally with the furnace, while the strip furnace structure occupies a large area, has a lot of heat loss, a long production cycle, low efficiency, and consumes a lot of power. An improved strip furnace structure with one-time molding and continuous production, while still occupying a large area, it also puts forward high technical requirements ...
