No. 7 EAF is a 220ton furnace with a current maximum steel output of 85 tons per hour (tph). The project will make a number of improvements to No. 7 EAF to increase its maximum shortterm steelmaking capacity to 183 tph and its annual production to 1,284,800 tons per year (tpy).
The primary source of postconsumer scrap is the automobile, and in 2004, the steel industry recycled million tons of iron and steel scrap from 14 million vehicles. Process Description In a minimill, scrap metal is melted and refined in an electric arc furnace (EAF) to make steel products.

Ladle Metallurgy Stations (LMS) play a crucial role in ensuring the quality of steel products. ... Initial and final slag compositions are commonly sampled manually from the furnace and analyzed in a laboratory using Xray Flouresence (XRF) or Inductively Coupled Plasma (rep) teclmiques.
Secondary metallurgy, also known as tap ladle metallurgy, is the set of processes and operations that aim to transform the ... electric power in the ladle furnace studied in the report. In order to study the industrial viability of the liquid addition of the various ferroalloys, several
However, in industrial practice, the time interval between aluminum deoxidation of the liquid steel in the ladle and pouring the mold is not sufficient for inclusion flotation, especially for small (<2 µm) nonmetallic inclusions. Most of the alumina inclusions are small and remain in the molten steel.
and routine staff training enable ASO Siderurgica and ASO Forge to guarantee a consistently high ... 1990 saw the installation of the first ladle furnace (LF) and the first vacuum degassing (VD) plant, as a result of ... metallurgy and is promoted by the Brescian Industrialists
Ladle Metallurgy. After tapping of steel from a primary steelmaking furnace such as BOF, EAF or EOF, molten steel for high quality or specialty applications is subjected to further refining in a number of alternative processes collectively known as ladle metallurgy.
Ladle Furnace (LF) Molten steel treated in Ladle Furnace is covered by a layer of desulfurizing slag. The graphite electrodes are submerged into the slag, which protects the ladle lining from overheating produced by the electric arcs. The arcs are capable to heat the steel at the rate about 5°F/min (3°C/min).
The size and shape of the ladle, the location of the porous plug, the location of the ferroalloy addition, and the sampling location are illustrated in Figure 1. Heat 1 was the twentyfirst heat of the ladle refractory campaign and the sixth heat on the alumina porous plug.
Figure 9: Maximum steel velocities in the ladle as a function of ladle age and stirring intensity. The plot shows that in the oldest ladle are the velocities almost twice as high than the velocities in a new ladle. This probably leads to a higher erosion of the ladle wall resulting in more inclusions in the steel.

After the ladle treatment the ladle is transported to the casting station and the steel is cast by continuous casting or ingot casting. The process in the scrap based route consists of melting steel scrap in the electric arc furnace (EAF) and then tapping the steel in to a ladle.
