Square-shaped tungsten molybdenum induction sintering furnace

Abstract

The invention provides a square-shaped tungsten molybdenum induction sintering furnace which comprises a heating element, a fire resistance device, an induction coil, a furnace body, a lifting systemand a skip car. The heating element, the fire resistance device and the induction coil are arranged in the center of the bottom part in the furnace body; the fire resistance device is located outsidethe heating element; the induction coil is arranged outside the fire resistance device; the skip car is arranged on a lifting platform at the lower end of the lifting system and is located under the furnace body; and the top end of the lifting system is located on one side of the middle lower part of the furnace body. According to the square-shaped tungsten molybdenum induction sintering furnace provided by the invention, the heating element, the fire resistance device and the induction coil adopt rectangular structures, so that a sintered tungsten molybdenum slab product can be horizontally placed on a placement bottom support, the bending deformation of the sintered material is improved maximally, straightening and levelling processes of a tungsten molybdenum product are greatly reduced,the production cost is reduced, and meanwhile, the influence on the product quality due to heating and pressure processing in the correcting process is avoided.

Description

technical field [0001] The invention belongs to the field of tungsten and molybdenum processing equipment, in particular to a square tungsten and molybdenum induction sintering furnace. Background technique [0002] Medium frequency induction sintering furnace is an important equipment widely used in special metal processing industries such as tungsten and molybdenum. Induction heating is one of the good forms of electric heating. It uses Faraday's electromagnetic induction principle to convert electrical energy into heat energy, so that the three-phase power supply becomes intermediate frequency alternating current through the intermediate frequency induction power supply. When the alternating current passes through the induction coil, it is An alternating induction magnetic field is generated, that is to say an alternating magnetic flux Φ whose magnitude and direction change with time is generated. When a piece of conductive metal (that is, tungsten, molybdenum workpiece)...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of low space utilization, high energy consumption, low efficiency, high cost, and easy deformation of the slab during the sintering process of the existing slab, the invention provides a square tungsten-molybdenum induction sintering furnace. The middle heating element, refractory device, and induction coil all adopt a rectangular structure. This structure allows the sintered tungsten-molybdenum slab products to be placed horizontally on the discharge bottom support, which greatly improves the bending deformation of the sintered material and greatly reduces The straightening and leveling process of tungsten and molybdenum products reduces production costs and avoids the impact of heating and pressure processing on product quality during the calibration process
