drum stainless steel slag lime

MPA Mineral Products Association Products

An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current. The slag is formed through the addition of lime, which is added to remove non-essential elements from the steel. The slag has a lower density than steel and therefore floats on top of the molten steel.

Lime, an essential component in the steel industry

In the case that the objective is to obtain stainless steel, the refining process is carried out in a so-called AOD converter and not in a ladle furnace because the decarburization of the steel must be extreme (0.03% C). In this AOD process lime is also added both for the desulphurization as well as for the dephosphorization and slag formation.

Carlos Thomas, Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.

Effect of Lime on Stability of Chromium in Stainless Steel

The stabilization of chromium is of great importance to the use of stainless steel slag (SSS), and the influence of lime on the stability of chromium is currently unclear. In this work, the variation of phase transformation and chromium distribution with slag basicity (CaO/SiO2) were investigated experimentally, and the leaching ability of chromium was evaluated.
