Slag Darts, Slag Dart Dispatching Machine Manufacturer

In order to produce clean and high quality steel, there is an increasing requirement for reducing the slag carryover from BOF converters. The use of slag darts is one of the well known means to achieve this goal during steelmaking process. We at YUNTIAN provide not only quality slag stopper darts but also complete slag control system solutions to leading steel producers worldwide. Performance slag dart dispatching machine is also available to help users precisely locate the slag dart tail into the tap hole, thus ensuring optimized slag stopping efficiency. Backed by vast experience in the design and production of slag limiting devices and refractory products for BOF converters, we are able to provide our valued customers with a full technical support service. We welcome you to contact us today if you have related demand on BOF refractories.

    1. Slag Dart Dispatching Machine (Robot for Slag Dart Insertion)
    2. Slag Dart Dispatching Machine (Robot for Slag Dart Insertion) The slag dart dispatching machine is an automatic robot for slag dart insertion. It automatically inserts slag darts into the taphole, thus reducing slag carryover from the BOF converter. It also supports manual operation in case of PLC system failure.
    1. Slag Stopper System (Taphole Slide Gate System for Slag Control)
    2. 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 Dart Tail
    2. 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 Ball
    2. 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 Darts (for 30-150 Ton BOF Converters)
    2. 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% .
