Boiling furnace desulfurization

Desulphurization in a Ladle Furnace

The principle of desulphurization is to transfer the sulfur dissolved in the liquid steel to a CaO-rich slag phase. This process is typically carried out in a ladle furnace (LF). For this process to be successful, two conditions need to be fulfilled: The slag must be fully liquid (liquid fraction > 0.9). This is required for kinetic reasons.

A Review of Modeling Hot Metal Desulfurization

1 Introduction Hot metal desulfurization serves as the main unit process for removing sulfur in blast-furnace-based steelmaking. Hot metal desulfurization is commonly conducted in a ladle or a torpedo car, 1 using a desulfurization reagent that is either injected into the metal bath or added on top of it. 2 From the thermodynamic point of view, the fundamental requirement for …

Desulfurization

Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule ( e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams. [1] These processes are of great industrial and environmental importance as they ...

Cyclic Use of Ladle Furnace Refining Slag for Desulfurization

 · Industrial experiments were carried out to study the cyclic use of ladle furnace refining slag on desulfurization. Sampling of refining slag and steel were undertaken simultaneously at roughly equal intervals of time. The desulfurization capacity remained almost unchanged in the recycling slag compared with the primary slag. The amount of lime added was gradually …
