•Customize slag darts
used for 30-300 ton BOF converts based on your requirements
In the converter steel-making
processing, a large amount of molten steel slag is produced when smelting in
the BOF. The slag dart is a cone shaped plug with a refractory covered guiding
rod, it has three slot design which is enough for the liquid metal to flow and
block the slag. The slag dart is inserted into the taphole toward the end of
the tapping operation by slag blocking dart application machine to block slag
inflow ladle, the performance can be increased to 96%, Slag layer< 40mm. The
slag dart has an obvious effect on increasing steel yield and purity as well as
the quality and mechanical performance of steel.

Slag Dart is usually used
in converter tapping process. Blocking slag in tapping process reduces
phosphorus in molten steel, and increase the alloy consumption; reduces various
objects mixing into steel, improves the steel quality; reduces slag sticking in
the ladle, improves the ladle life; reduces refractory consumption, and
providing better conditions to refine steel.
