Silicium Reversion From Steelmaking Slags

Slag Detection System Based on Infrared Thermography in ...

When liquid steel is tapped from a basic oxygen furnace (BOF), it is essential to minimize the quantity of slag carry-over, because the high level slag may result in the oxidation and the phosphorus reversion during the secondary metallurgy process. The system with the infrared thermal camera is widely used to detect the slag.

Abstract. The behavior of phosphorus in CaO-SiO 2-Al 2 O 3-MgO-P 2 O 5-Fe t O slag systems during solid Al and carbon deoxidation was investigated at 1873 K. Furthermore, an X-ray apparatus (vertical resistancetube furnace equipped with an X-ray inspector system, which enhances the real-time observation of the generated gas in slag) was introduced to confirm the possibility of the vaporizing ...
