Embodiment 1

[0108] like figure 1 As shown, this embodiment provides a method for calculating the movement of inclusions in the VIM smelting process based on COMSOL simulation, and the method includes the following steps:

[0109] (1) Establish the geometric model of the vacuum induction furnace.

[0110] like figure 2 As shown, the geometric model of the vacuum induction furnace is established, and the geometric dimensions of the model are as follows: the height of the furnace charge is 195mm; the size of the crucible is φ340mm×H280mm, and the wall thickness is 20mm; the size of the insulation material is φ400mm×H310mm, and the wall thickness is 30mm; 28mm, the gap between the coils is 8mm, and the number of coil turns is 8 turns. According to the above parameters, COMSOL was used to draw the geometric model of the vacuum induction furnace, and the outermost layer of the geometric model of the vacuum induction furnace was defined as an infinite element domain, and the coordinate syste...

The invention is of great significance to the realization of the high-purity target of the alloy material.

Description

technical field [0001] The invention belongs to the technical field of metal production and refining, and in particular relates to a method for calculating the movement of inclusions in the VIM smelting process. Background technique [0002] With the rapid development of modern industrial technology, the performance requirements of metal materials are getting higher and higher, and purification has become an important direction for the development and application of metal materials. Inclusions seriously affect the mechanical properties of alloy materials, especially when smelting high-quality alloy materials, they need to be strictly controlled. Vacuum induction melting (VIM) is carried out under vacuum conditions, has a strong stirring function, and can effectively remove impurities and gases in the alloy. Smelting method. It is of great significance to study the movement of inclusions in the process of VIM smelting, so as to promote the removal of inclusions, to achieve ...
