VD furnace, i.e. vacuum degassing furnace, is a key equipment in the metal refining process. Its working principle is to remove gases and non-metallic inclusions in the metal melt through heating and degassing treatment under vacuum environment. This process significantly improves the purity of the metal and reduces internal defects, which in turn improves the overall properties of the material.
Increased purity means a more uniform distribution of stresses within the material and enhanced mechanical properties such as strength and toughness. At the same time, the high purity of the material in the corrosion resistance, oxidation resistance and other aspects of the material also shows more excellent performance, extending the service life of the material.
In addition to enhance the purity, VD furnace can also accurately control the chemical composition of the molten metal. By adjusting the proportion of alloying elements added and degassing conditions, VD furnace can optimize the chemical composition of the material to meet the special needs of different applications on the material properties.
For example, in the production of alloy steel, the VD furnace is able to precisely control the content of carbon, silicon, manganese and other elements to obtain alloy steel with specific mechanical properties and corrosion resistance. This optimization of chemical composition not only improves the performance of the material, but also expands its scope of application.
VD furnace secondary refining process can also improve the organizational structure of the material. In a vacuum environment, the atomic activity in the metal melt is enhanced, which is conducive to the formation of a more uniform, dense crystal structure. This structural improvement allows the material to disperse stresses more uniformly when subjected to force, improving the material's fatigue and fracture resistance.
In addition, the refining process in the VOD furnace eliminates residual stresses in the material, reducing problems such as cracking and deformation caused by stress concentrations. This helps to improve the processing performance and yield of the material.
In summary, the VD furnace by enhancing the purity of the material, optimize the chemical composition and improve the organizational structure and other aspects of the role, to achieve the overall enhancement of material properties. This enhancement is not only reflected in the mechanical properties, corrosion resistance and oxidation resistance of the material, but also in the processing performance and service life of the material.
