Tungsten bar stacking crucible for intermediate frequency furnace

Abstract

The invention discloses a tungsten bar stacking crucible for a intermediate frequency furnace. The tungsten bar stacking crucible comprises a pot body and a supporting cylinder, wherein the pot body is formed by stacking and assembling a plurality of stacked tungsten bars, and an upper portion and a lower portion of the pot body are open; the supporting cylinder is arranged below the pot body; a limiting ring is fixed to an inner wall of the pot body; a blocking disc is fixed to the top of the supporting cylinder; the blocking disc is slidably arranged on the inner wall of the pot body and abuts against the bottom of the limiting ring; and a plurality of sleeves and a plurality of expansion blocks are fixed to a side face of the top of the supporting cylinder. According to the invention, the supporting cylinder is filled with mercury, the mass of the supporting cylinder and the mass of the mercury are very large, the gravity center of the whole pot body moves downwards, and the bottom of the pot body is very stable, so that the pot body stands stably and is high in safety; the mercury is cooled in the supporting cylinder, and the volume of the mercury is reduced, so that negative pressure is generated in the supporting cylinder, a communicating pipe and a telescopic cylinder; a telescopic rod is contracted into the telescopic cylinder, so that a clamping head and a clamping sleeve are separated; and a clamping rod is not supported and inclines downwards, so that the blocking disc can be detached from the interior of the pot body, high-temperature liquid metal can be poured out from the bottom of the pot body, and the use safety is very high.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency furnaces, in particular to a tungsten bar stacking crucible for intermediate frequency furnaces. Background technique [0002] The intermediate frequency furnace is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency as energy heating equipment. The crucible is placed in the induction coil of the intermediate frequency furnace, and high-density magnetic force lines are generated in the induction coil, and the metal contained in the induction coil is cut. Materials, generate a large eddy current in the metal material for heating; [0003] At present, CN201921922060.3 is disclosed in the prior art, a tungsten rod stacking crucible for intermediate frequency furnaces. The utility model utilizes a number of tungsten rods to be bent and formed by splicing and stacking, and the tungsten rods can be bent by tungsten plate scraps. The tu...
