Product Description

Slag Dart

Refractory & Ball Slag Dart, Steel Plant Control Slag Dart, Slag Dart For Steel Making Supplier

Features

•Higher bulk density

•More resistant to impact, burst and erosion

•Customize slag darts used for 30-300 ton BOF converts based on your requirements

Description

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.

Application

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.
