CONEPLAST  flush slag stopper


Slag limiting system for tiltable converter
Cutting off the flush slag, reduction of the
transferred slag during tapping
Prevention  against starting vortex
Reduction in the use of  aluminium
 and alloy  materials
Lower slag amount means
 constant steel quality
 lower amount of oxygen
Cleaner ladle lid
Longer life of the ladle wall


DEFLUX anti - vortex systemfor tundish
During continuous casting process liquid steel is transferred from the tundish into the mould. The casting speed is regulated by stoppers, sliding gates etc. At the end of the sequence and during ladle changes within the  sequence the risk is high that vortex occoured which transfer slag from the steel surface into the mould. This will lead to inclusions within the strand. The DEFLUX system helps to stop those vortex.


FLOWDART converter slag limiting for top-slag

Dart setting machinery and FLOWDART object are used for slaglimiting of the rest top slag during tapping. Dart and Coneplast Stopper cut off 90 % of the total possible slag transfer
