The robust SIMETALCIS Vaicon Stopper provides steelmakers with the means for tight control of slag carry-over at the end of tapping. Consisting of a cylinder and cast iron nozzle mounted on a support structure which is installed close to the tap hole, the nozzle is slewed into the tap hole and actuated either manually or automatically by the IRIS slag indication system. The contact-free infrared identification system offers optimal differentiation between slag and steel.
SIMETALCIS Vaicon Stopper
High quality steel grades demand low content of phosphorus. Reduction of the carry-over slag during tapping and further ladle treatment is the main reason for phosphorus retention to steel.
Therefore decrease of the carry-over slag amount becomes more important when producing high quality steels.
Slag retention system using pneumatic sealing effect using nitrogen gas with no mechanical contact with the tap hole. This solution makes the slag stopper independent from the tap hole wear ensuring the slag retention is always efficient.
