Embodiment 1

[0029] In order to overcome the existing problems of large energy consumption, small production capacity and high cost, the present invention provides such Figure 1-10 A square heating element device for a tungsten-molybdenum sintering furnace is shown. After changing the round heating element into a square heating element, the sintered tungsten and molybdenum products can be placed flat on the bottom support, which improves the maximum The bending deformation of the sintered material greatly reduces the straightening and leveling process of the tungsten and molybdenum products, and improves the product quality. The square heating element can increase the utilization rate of the furnace, with less energy consumption and large production capacity. The recovery rate of materials after the square heating element is scrapped can reach more than 70%, which can save a lot of valuable tungsten materials, greatly reduce production consumption and save production costs.

Embodiment 2

[0034] Based on Example 1, in this embodiment, the long tungsten bar 4 is longer than the short tungsten bar 2, and both the short tungsten bar 2 and the long tungsten bar 4 are cut from rolled tungsten plates.

[0035] The spigot 3 includes a convex slit 6 and a concave slit 7, the convex slit 6 and the concave slit 7 are respectively arranged on the long tungsten bar 4 and the short tungsten bar 2, and the two spigots are engaged, When the convex seam 6 and the concave seam 7 are engaged, an expansion joint is left.

[0036] The range of the expansion joint is 0.2-5mm.

[0037] In the present invention, the short tungsten bar 2 and the long tungsten bar 4 are engaged through the seam 3, and the seam 3 is divided into Figure 5 Shown male relief 6 and Figure 6 The concave stop 7, the convex stop 6 and the concave stop 7 should leave a certain amount of expansion joints when occlusal, so as to avoid the deformation of the tungsten strip when the induced magnetic field passe...

Abstract

The invention provides a square heating body device of a tungsten-molybdenum sintering furnace. The square heating element device of the tungsten-molybdenum sintering furnace comprises a short tungsten strip, a spigot and a long tungsten strip; the short tungsten strip and the long tungsten strip are connected through the spigot, the short tungsten strip and the long tungsten strip are spliced toform a layer of square tungsten strip, four corners of the square tungsten strip are corners of a heating body, all layers of spliced tungsten strips are overlapped layer by layer to form the heatingbody, and joints of the long tungsten strip and the short tungsten strip are mutually staggered during overlapping. In the square heating element device of the tungsten-molybdenum sintering furnace, each tungsten strip is in a free state without welding. When the service life of the heating body is prolonged, the tungsten strip can be disassembled, the tungsten strip with small deformation amountcan be recycled to be used for manufacturing a new heating body, in actual production, the recovery rate of the scrapped material of the heating body can reach 70% or above, a large amount of valuabletungsten materials can be saved, production consumption is greatly reduced, and production cost is saved.

Description

technical field [0001] The invention belongs to the field of tungsten and molybdenum processing equipment, in particular to a square heating element device of a 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, mol...
