Introduction
With the development of secondary refining,tapping with less slag for converter is required. Several series slag skimmers have developed for converter. Such as cross furrow sphere type,truncated cone type,polyhedr-
on type,hemisphere type and guiding bar type.Skimming eftects can be improved if the slag skimmer is designed in truncated cone with compound wall.A new slag stopped has been developed recently.
Characteristics
1.High strength.No explosion when in use.
2.The accuracy and slag skimming rate of slag skimming can be above 95%
3.Fine slag skimming effect??the slag thickness in the ladle is less than 60mm(Obvious liquid steel stream after tapping)
Cautions
1.Package is done under the user's requirements
2.Moisture proof??avoid wild loading and unloading in storage and transportation
