The new VAI-CON stopper system developed by Voest-Alpine Industrieanlagenbau (VAI) is a highly effective solution for reducing slag carry-over in converter steelmaking. Its development is the result of many years of engineering and operational experience in close cooperation with steel producers. The modularly designed system and the accompanying quick-change equipment reduce maintenance downtime to less than one hour in every 5000 heats. Excellent functionality, long-term availability, low operating costs and reliable, automatic operation are the main advantages of the new stopper.
