It's the job of tertiary metallurgical plants to create unique technological properties in ultra-pure steels, super alloys, cast alloys, and nonferrous metals. These peak-performance, heavy-duty materials are used in demanding, high-tech industries such as aviation, aerospace, power generation, and automotive. There is no alternative technology in this high-end field.
VIM is a powerful process applied to melt down selected scrap and refine the resulting liquid steel. The process involves casting ingots under vacuum, which further improves final-product quality.
VIM works with dedicated vacuum chambers for melting and casting. They are connected by launder and tundish units.
The crucible comes with a vacuum-tight electricity supply and can be exchanged easily using the advanced lifting system.
It's a special advantage that the mechanical pump
system generates extra-strong vacuums.
There is also a charger that ensures clean material feeding under vacuum.
Finally, an integrated deslagging machine removes the slag from the crucible.
