Optimization of quality of charcoal for steelmaking using statistical analysis approach [PDF]
, 2014 Steel is one of the most important materials used in modern society. The majority of the steel produced today is based on the use of coke and contributes a lot to greenhouse gases emission.

steel research international, EarlyView.This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

steel research international, EarlyView.The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Eminent Domain & Bank Boycotts: The Tri-State Strategy in Pittsburgh [PDF]
, 1983 [Excerpt] American steel corporations are currently in the process of cutting as much as 20 to 25 per cent of their productive capacity, much of it in the Pittsburgh area. With U.S. Steel\u27s recent move to buy steel slabs from overseas steel companies,

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Uncertainty management by relaxation of conflicting constraints in production process scheduling [PDF]
Mathematical-analytical methods as used in Operations Research approaches are often insufficient for scheduling problems. This is due to three reasons: the combinatorial complexity of the search space, conflicting objectives for production optimization ...

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace
steel research international, EarlyView.This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.
