Description
The slag dart dispatching machine is a special device used for optimizing the production of BOF 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.
After the Slag Dart Machine completes the whole process, there is a significant reduction of slag mixed in the ladle, and by reducing the alloy consumption, steelmaking process along with economic advantage is highly improved.

The old converter finished the slide gate stopping slags application through tapping modification.
Stopping slag with slide gate is successful which can reduce the cost of production.
Description
The old converter finished the slide gate stopping slags application through tapping modification.
Stopping slag with slide gate is successful which can reduce the cost of production.
Slag tapping amount can be controlled around 40 mm, which provides requirement for the production of variety of steel.
1. Higher than 98% slag stopping rate, effectively reducing the average slag thickness of ladle, slag thicknessâ?¤40mm(no synthetic slag)
2. Simple and rational structure, safe and reliable use, simple operation and convenient repair and replacement
3. Device closing speed second;
4. The skateboard replace time 15 mins /time (no inner nozzle brick,No manipulator);
5. The skateboard and outside nozzle average service life 12 times(no flow control)
Inner nozzle average service life 40 times (synchronize replaced with tapping hole);
average service life 24 times(replace alone);
Application
To reduce the slag quantity in the process of the tapping is important part to improve the quality of molten steel.
