Metallurgy

The processing of metals is a tough business: bending, pickling, heating and cooling of materials, heat treatment of steels, surface treatments and at the same time maintaining a high-quality surface finish – these are just some of the demands Schubert & Salzer’s valves overcome every day in many metal processing operations. It must be guaranteed that valves operate smoothly in hot ambient conditions and harsh environments. But it is not just heat resistance that is a determining factor, as in metal processing quite often aggressive media are involved which the installed valves must also withstand.

Our angle seat valve has particularly proven itself. As an extremely versatile valve, it copes easily with millions of switching cycles, high temperatures and even aggressive media. Besides the angle seat construction, the seat valve is also available in right-angle, flanged and angle seat flanged body versions. Available with a variety of connection options (from socket weld, threaded and flanged connections, through Tri-clamp fittings), this seat valve can be employed in various operations. Also, there is a choice of various types of actuation: pneumatic, motor-driven or manually-operated.

The motorized version of the Schubert & Salzer angle seat valve is used, for example, for metering the nitrogen in inert furnaces, where the gas is applied to the metal surface, or for metering cooling air in galvanizing facilities. Angle seat valves are also used for steel pickling where the effluent water needs to be processed. Another application is in the regulation of air flow in filtration plants when it is necessary to reduce the amount of fine dust from steel processing.




Application Report - U. S. Vanadium

Precise steam regulation in the production of extremely pure vanadium oxides

Almost 200 years ago, the Swede Nils Gabriel Sefström discovered a new element. Inspired by the rich colouring of its chemical compounds, he called it “vanadium” after Vanadís, the Scandinavian goddess of beauty. Today, the world’s purest vanadium compounds are manufactured on an industrial scale by U.S. Vanadium. Sliding gate valves help to reach and maintain the optimal process temperature.

Application Report - thyssenkrupp AT.PRO tec

Revolutionary oxygen impulse technology for steel production

thyssenkrupp AT.PRO tec GmbH is well known for the development of the sequence impulse process. When used on cupola furnaces, it considerably increased their cost-effectiveness in the past. In over 10 years of development work with Schubert & Salzer as their partner, Dr Rainer Klock and the team at AT.PRO tec succeeded in getting the SIP technology to work on blast furnaces, too, with the help of sliding gate valves. The story of a researcher on the way to becoming a plant manufacturer.

Application Report - BMW

Sliding gate valves optimise the process reliability of light metal die casting

In low pressure die casting, e.g. light metal engine blocks, the casting machines are filled by pressurising the furnaces. This requires highly precise pressure control along defined pressure curves in order to be able to produce a high quality casting and, for example, to prevent the metal pillars from moving around in the mould. In each case, BMW replaced the pressure control previously used for this purpose in its Landshut light metal foundry with a single sliding gate valve from Schubert & Salzer Control Systems.
