Caster Metallurgist - Improving Steel Cleanliness through out process; reducing inclusion formation on high sulfur grades typically used in the automotive industry.-Created new practice to improve
Historically, the steel industry has used the blast-furnace method with coal-fired plants to process iron ore. This method is costly, inefficient, and generates significant pollution. As more producers have turned to recycled-steel metals, arc-furnace technology has become more prevalent, with the promise of lower costs, longer operations and uptime, and less pollution.
Vacuum Degassing of Steel
During the steelmaking process, while the molten steel is still in the ladle and before it is poured, the steel must be degassed in order to: (1) reduce/eliminate dissolved gases, especially hydrogen and nitrogen; (2) reduce dissolved carbon (to improve ductility); and (3) to promote preferential oxidation of dissolved carbon (over chromium) when refining stainless steel grades. In the steel
AISI | Electric Arc Furnace Steelmaking
The electric arc furnace operates as a batch melting process producing batches of molten steel known "heats". The electric arc furnace operating cycle is called the tap-to-tap cycle and is made up of the following operations: Furnace charging Melting Refining

Melt Shop Processes - Nucor Steel Gallatin
The process of melting a charge of scrap is called a heat. The melt shop computer system identifies each production batch with a unique heat nuer. To begin melting, the single 30" diameter graphite electrode is lowered into the furnace, and an electric arc is struck between the top and bottom electrodes.
Since then, ArcelorMittal Dofasco has developed the most automated steelmaking process in the world with full automation from the start of the oxygen blow to the end of steel tapping. Automation also includes auto end-point control with offgas analysis, infrared slag detection, auto slag stopper, auto ladle car movement with laser positioning of the steel ladle, auto ladle sanding and

Numerical Investigation of Desulfurization Kinetics in Gas …
A quick modeling analysis approach for predicting the slag-steel reaction and desulfurization kinetics in argon gas-stirred ladles has been developed in this study. The model consists of two uncoupled components: (i) a computational fluid dynamics (CFD) model for predicting the fluid flow and the characteristics of slag-steel interface, and (ii) a multicomponent reaction kinetics model for
AIST - 2019 AISTech Conference Proceedings
Secondary steel-making is a critical process that follows the basic oxygen furnace or electric arc furnace prior to continuous casting. Some chemical elements are added, while others are removed during the refining process at the Ladle Metallurgy Furnace (LMF) in order to fine-tune the composition of steel to meet customers’ requirements.
