The semi-open electric arc furnace can produce either SiMn, which is cast on sand, or high-carbon FeMn, from which slag is raked and processed in another building. New EPA legislation requires high efficiency at-source fume capture and a maximum average opacity reading of 8% from building roof tops in a "tap to tap" cycle.

Ferrochromium

Rauf Hurman Eric, in Treatise on Process Metallurgy: Industrial Processes, 2014. 1.10.3.3.2 Silicon Content of High-Carbon Ferrochromium. The silicon content of the ferrochromium should be low as it is an undesirable element in stainless steels. Low silicon content is favored by a low operating temperature, high carbon content in the ferroalloy and a basic slag.

Modelling of the Refining Processes in The | Steelmaking ...

An example of this kind of physical modelling is the modelling of metal and/or slag flows using small scale water models. The purpose of this section is to present the essential features that need to be considered in the modelling of the SAF, EAF, CRK and AOD processes used in the production of ferrochromium and stainless steels (cf. Table 3).

Making Shaping

It also uses liquid steel from an electric arc furnace or similar melter. The major impetus for its development was the idea to substitute steam as the diluting gas rather than argon. The process was developed by Uddeholm of Belgium and Creusot-Loire of France. The converter is bottom-blown thus differentiating it from the side-blown AOD converter.
