Slag Stopper for Converters
1.Properties and features
With the development of secondary refining
technology
， slag-free tapping from the
converter is required now. We have developed series of slag
stoppers for steel convertors such as ball type with cross furrow,
circular truncated cone type, polyhedral type, hemispheroid type,
with the guide rod type, etc.. It can also be designed into conical
composite wall type to further improve the blocking slag effect. A
kind of high damping slag stopper is developed recently. There is
no burst when used with high strength. The hit rate of the blocking
slag and the slag rate all exceed *5% and the blocking slag effect
is good. The slag thickness in the steel ladle is less than *0 mm (
There are obvious signs of charge flow when molten steel is
discharged completely.)
