Abstract

The invention provides a square induction coil for a 2500 DEG C tungsten-molybdenum sintering furnace. The square induction coil comprises a copper pipe, bakelite stand columns, an extraction electrode and an electrode flange, wherein the copper pipe is wound into a square coil shape; the bakelite stand columns are evenly distributed on the outer surface of the copper pipe; the distance between every two adjacent bakelite stand columns is 240-560 mm; the extraction electrode is arranged on the outer surface of the copper pipe and connected with the electrode flange; cooling water is introducedinto the copper pipe of the copper pipe; the face, away from the extraction electrode, of the electrode flange is a conductive sealing face; and the conductive sealing face does not leak under the water introducing condition. After the round induction coil is changed into the square coil, a sintered tungsten-molybdenum product can be flatly placed on a discharging bottom support, bending deformation of the sintered material is improved to the maximum degree, the straightening and leveling process of the tungsten-molybdenum product is greatly reduced, and the product quality is improved. According to the square induction coil, the utilization rate of a hearth can be increased, energy consumption is low, and the productivity is large.

Description

technical field [0001] The invention belongs to the field of tungsten and molybdenum processing equipment, in particular to a square induction coil used in a 2500°C tungsten and molybdenum 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,...
