ALD Vacuum Technologies, Germany, has developed the Vacuum Induction Degassing (VID) furnace concept for special applications in the ferrous and non-ferrous metals industry for charge weights up to 30 tons. Smaller steel shops and foundries will be able to produce high quality vacuum treated steels with the VID furnace in one step. The temperature losses during degassing treatment are compensated by induction heating.
Whenever pouring under vacuum is not specified or not required for metallurgical reasons, this bell type furnace with open-air teeming is recommended for its favorable economics. All important secondary metallurgy treatment steps are done in one single unit. These steps include melting under vacuum, decarburization, desulfurization, deoxidation, removal of hydrogen and nitrogen, exact adjustment of chemical analysis, cleaning, alloying, and heating.
The modified VID-Pro furnace allows not only meltdown and vacuum-refining, but also pouring under protective inert gas. The vacuum lid stays in closed position during melting, refining, and casting. Gas-pick-up during tapping can be minimized.
The VID-Oxy furnace is dedicated to economical production of high-chromium steel grades, accomplished by using low-cost raw materials. Soft oxygen top blowing by means of a gas lance allows additional removal of carbon. With the VID-Oxy furnace concept, it is possible to carry out metallurgical work such as degassing, deoxidation, desulfurization, and removal of oxide-inclusions with a reactive basic slag and chemistry adjustment under vacuum. The results are very low carbon and nitrogen contents and high chromium yield. The VID-Oxy furnace is the ideal alternative to conventional steel degassing with EAF/VD/VOD at charge weights up to 30 tons.
