Smelting and casting device for laboratory

Abstract

The invention belongs to the technical field of casting and discloses a smelting and casting device for a laboratory. The smelting and casting device comprises a crucible holder, a smelting crucible,a support and a pouring pull rod, wherein the smelting crucible is arranged on the crucible holder; the support is connected to the crucible holder and is used for supporting the crucible holder in the smelting position, or the smelting crucible and the crucible holder are transferred through the support, and the crucible holder can rotate relative to the support, so that metal solution in the smelting crucible is poured into a mold. One end of the pouring pull rod is detachably connected to the bottom of the crucible holder, the pouring pull rod is pulled, and thus the smelting crucible can be driven to rotate relative to the support. The support and the pouring pull rod are arranged, thus the metal solution in the smelting crucible can be poured directly, transfer with a casting ladle isnot needed, too much heat loss of the smelted metal solution is avoided, the smelting and casting device is suitable for the smelting and casting process of a small amount of metal in the laboratory,and casting quality can be improved.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a laboratory melting and casting device. Background technique [0002] The melting and refining process is one of the casting production processes of metal materials. It is to put metal materials and other auxiliary materials into the heating furnace for melting and tempering. The raw material melt undergoes certain physical and chemical changes in the high-temperature furnace to produce crude metal or Pyrometallurgical processes of metal concentrates and slags. When producing metal castings, metal raw materials need to be smelted, and then the smelted metal solution is cast into a forming mold. [0003] The traditional production process is to melt the raw materials at a high temperature in a melting furnace, then transfer them through a ladle and cast them into a mold for molding. This production process includes two transfer procedures, therefore, the metal solution loses mo...

Problems solved by technology

In the extensive smelting process or the production process with low requirements, the above-mentioned method can still be used for mass production, but as various casting methods have higher and higher requirements on the metal smelting process, the crucible smelting process in the prior art The method has been difficult to meet the requirements

Especially for laboratory smelting and casting, due to the small amount of raw materials, heat loss may cause segregation of some components in the alloy melt, and it is easy to include gas in it, which increases the porosity of the solidified product; the temperature of the metal solution decreases It will reduce its fluidity and affect the subsequent casting process, thereby affecting the quality of castings

The above method of secondary transfer process through the ladle is not suitable for laboratory melting and casting
