  • Slag Dart Dispatching Machine (Robot for Slag Dart Insertion)The slag dart machine is a special device used for optimizing the production of basic oxygen furnace steelmaking. It improves the quality of the steel by reducing the slag mixed into the ladle and reducing the loss of ferroalloy.When the converter releases the molten steel, the device puts a slag dart into the tap hole to prevent the liquid slag mix into the ladle.
  • Slag Stopper System (Taphole Slide Gate System for Slag Control)The slag stopping system is a slide gate system installed at the tap hole of BOF converter. Based on the design philosophy of ladle sliding gate system for flow control, the slag stopper system is designed for slag control and includes a hydraulic drive system and an automatic slag detection system for intelligently control the opening and closing of the sliding gate.
    1. Slag Darts (for 30-150 Ton BOF Converters) We supply two kinds of slag darts to suit the demand of BOF converters with different processing capacity. Our slag dart heads are shaped into a circular cone with three steel flowing grooves on its outside. By using the shaped refractory, the slag stopping efficiency can be enhanced to no less than 90% .
    1. Slag Darts (for 160-300 Ton BOF Converters)Our range of slag darts is designed for slag control during steelmaking process, and thus is a kind of commonly used refractory material in BOF converters. The slag control system is suitable for BOF converters with capacity from 160 to 300t.
    1. Slag Dart TailThe slag dart tail is the guide connection structure for slag dart. It connects the head part (hemisphere) of the slag dart to play the function of guide positioning.
    1. Slag Stopper BallThe slag stopper ball was invented by the Japanese Nippon Steel Corporation in 1970. It blocks the tapping hole when the steel tapping is about to end to prevent the steel slag from flowing into the ladle by exploiting the principle of the density of the product being between that of the steel and slag, generally with the value of 4.2 to 4.5g/cm³.
    1. Slag Stopper (Used Outside BOF Converters) The slag stopper is mainly used outside BOF converters for slag control during tapping. When blowing oxygen during the smelting process, the slag control system can also prevent the molten steel splashing out.
