Industrial Applications

By "industrial applications" we mean a wide range of production processes that require vacuum technology.

By "industrial applications" we mean a wide range of production processes that require vacuum technology. The common denominator of these applications such as steel degassing, heat treatment, vacuum drying or helium leak detection is their use of pumps in challenging industrial type environments. They need to handle “more than just air” and must cope with this. Exactly what our industrial pumps are made for.

  • Heat Treatment

    One of the drivers in the field of vacuum furnaces is the ever-increasing demand for high-quality metal parts from the aerospace and automotive industries. These sectors demand modern components that are capable of meeting the highest standards. These standards can usually only be achieved by heat treatment under vacuum. 

    Unexpected furnace downtimes cause high production costs, as the production steps are usually designed according to the just-in-time model. The various heat treatment  applications present different challenges for the vacuum systems used. 

    Since 1850, our customers worldwide rely on our experience and expertise. Leybold  offers the best vacuum technology for every heat treatment application.

  • Secondary Metallurgy Steel Degassing

    VD / VOD processes Vacuum Degassing (VD) for alloy steels; Vacuum Oxygen Decarburising (VOD) for stainless steels. VD treatment is used to reduce the volatile gas content (e.g. hydrogen, oxygen, nitrogen) of the steel to enhance the steels capabilities. VOD treatment involves an additional oxygen blowing step to reduce the steels content of oxidizable compounds as e.g. carbon or phosphor. Additionally, the oxygen flow can be used for chemical heating of the melt (VD-OB process).

    RH / RH-OB (Ruhrstahl Heraeus) process: Enhances the yield of steel treatment under vacuum, typically utilized in integrated steel plants with a high and very frequent demand for vacuum treatment. The degassing processes are generally similar to VD / VOD. In a RH-system the lower end of the vacuum vessel bears two snorkels, which are immersed into the ladle bearing the steel bath. By evacuation of the vessel, the steel is lifted up into the treatment chamber.

  • Energy Storage

    The energy revolution we are facing also poses a technology challenge. Green energy supplied by photovoltaic plants and wind turbines is often not synchronized with the current demand. Overrun energy requires high-grade temporarily storage solutions. Efficient energy storage solutions are also needed to make e-mobility more attractive by increasing the range per charge and reducing manufacturing costs. Therefore the current Li-Ion-cell technology must be enhanced. Bespoken vacuum solutions for vacuum assisted production steps are needed. Leybold products can support all vacuum related process steps in Li-cell manufacturing and in addition enable mechanical systems to store energy.
