Ladle Metallurgy: Basics, Objectives and Processes | PPT
10. Ladle Furnace • The ladle with liquid steel is brought to the LF station, where a top cover is placed on the ladle and graphite electrodes are introduced. • In the LF, deoxidation and composition adjustments are carried out by additions, and the temperature of the melt is adjusted by arc heating (graphite elecrodes) • Bath stirring is achieved by …
Modeling of Ladle Refining Process Considering Mixing and Chemical
The mathematical description of a tank model for a gas-stirred ladle proposed by Murthy was applied in the present work. The nozzle was assumed to be located in the center of the ladle bottom. Hence, all the tanks are centrosymmetric. The volume of each tank in the stirring LF was defined based on the ladle dimensions.
