Interactive industrial application to represent isothermal sections of multi component phase diagram [PDF]

, 2019
“Make the slag and the steel will make itself” is an old phrase in steelmaking. The converter or basic oxygen furnace (BOF) process is a necessary step in the steel production during which carbon, phosphorus and other impurities present in the hot metal,

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

The behavior of manganese in oxygen steelmaking [PDF]

, 2019
Manganese serves as an important alloying element in commercial grades of steel and high levels of Mn can improve the mechanical properties of steel. [1] The chemical behavior of Mn in Oxygen Steelmaking is complex because the element is readily oxidised

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

steel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Phenomenological Prediction of Defect Formation in Continuous Casting of Steel Utilizing Fundamental Modeling and Machine Learning

steel research international, EarlyView.
In this article, decision tree classifiers are developed to predict defects in continuous casting of steel utilizing caster data from SSAB Raahe Works (Finland). Phenomenological quality criteria extracted from applicable process measurements and results from solidification and heat transfer simulations are utilized in prediction.
