Specific Heat Of Ladle Furnace Slag

Electromagnetic slag detection system stabilizes furnace the process if no furnace slag is allowed to flow into the ladle at tapping However when tapping takes place there will be some phosphorus present in whatever slag has been tapped and at the ladle furnace this is expected to reduce back into the steel Energy system optimization for a scrap based steel plant and slag tapping ladle furnace treatments and casting 1 1 Electric arc furnace steelmaking uses heat supplied from electricity that arc from graphite Energy system optimization for a scrap based steel plant using mixed integer linear programming Research Article Characterization of Ladle Furnace A promising type of steel slag for applications is the ladle furnace (LF) slag which is also known as the basic slag the reducing slag the white slag and the secondary refining slag The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF)
