Ladle Furnace an overview | ScienceDirect Topics

Ladle furnaces look like smaller versions of EAF furnaces, having three graphite electrodes connected to an arc transformer used for heating the steel. At the bottom of the ladle furnace, typically, there is a pipeline through which argon gas can be injected for stirring and homogenizing the molten steel in the furnace. By injecting desulfurizing agents (such as Ca, Mg, CaSi, CaC

Read the full analysis in PDF format. Download the Calculation File. About Desulphurization in a Ladle Furnace The ladle furnace fulfils many purposes in the steelmaking process. Desulphurization, which we will focus on in this example, is merely one of them. Desulphurization is usually performed by transferring sulphur (S) that is dissolved in the liquid metal to a CaO-rich slag phase, as

LADLE REFINING AND SLAG CONDITIONING

Temperature: With ladle reheating furnaces, temperature can be controlled to within ± 5 °F of the target temperature. Chemical Specifications: If the slag is well deoxidized, the carbon and alloy aims can be met within very tight tolerances. The slag phase has a tremendous impact on the steelmaking goals listed above, and will be discussed in detail in this session. The truth of the old
