Smelting device and alloy smelting method

Abstract

The invention discloses a smelting device. The smelting device comprises a crucible body. The smelting device is characterized in that a through hole used as a discharging hole is formed in the bottom part of a crucible, wherein a smelting sensing coil is arranged at the outside of the crucible, and the working length of the smelting sensing coil is not greater than the height of the crucible; the smelting sensing coiling is provided with a driving assembly in a connecting manner and is driven by the driving assembly to move opposite to the crucible in the axial direction of the crucible. With the adoption of the smelting device and the smelting device, the shortages caused by a discharging technology of toppling over the crucible in the prior art can be avoided; alloy raw material can be uniformly smelted; and moreover, the device and the method are convenient and reliable, applicable to various alloy smelting applies, and particularly applicable to a smelting alloy smelting technology with high requirement.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a smelting device and a smelting method using the 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. The smelting utensils used in the process of alloy smelting are often crucibles. In the smelting process, the alloy raw materials are heated and melted to form a uniform melt, and then the crucible is turned over to pour the melt into a container in the subsequent process, such as pouring into a die-casting mold for subsequent processing. As a smelting tool, crucibles have been widely used in ...

AI Technical Summary

Problems solved by technology

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

[0003] The main disadvantages of crucible smelting and dumping are as follows: (1) The alloy melt is prone to splash during pouring, resulting in material loss; (2) Since the heating has been stopped, the heat loss during pouring may cause The segregation of some components in the alloy melt, and the easy inclusion of gas in it, increases the porosity of the product after solidification; (3) The kinetic energy of the alloy melt during the pouring process is relatively large, and the cooling time interval in the subsequent process container is long. It is easy to stratify after solidification; (4) Affected by the turning angle of the crucible, the inside of the melting crucible is prone to residue, which affects the life of the crucible, and also affects the composition consistency of the next batch of smelted alloy products

In the above technical solution, although the problems caused by dumping the crucible are improved, since the conventional heating method often adopts resistance heating or induction heating, the bottom of the crucible is a part with poor heating effect. Second, in order to obtain a uniform melting effect, the blanking The hole sealing and control structure are uniformly placed in the heating source, so that the closed structure of the blanking hole formed in this way is easy to fail in high temperature environment, resulting in the situation that the solution cannot flow out or leaks
