By: John R. Lanahan Inland Steel Company is the fifth largest steel company in North America and is the largest .producer of steel at one plant. More than 6,000,000 tons/year can be shipped, of which about 60% are flat rolled, products, inland has a series of subsidiaries in warehousing, metal building, and containers which are also steel users. Total corporate sales are in excess of $2 billion...

cost reduction is one of the methods applied for improving the productivity of organizations. in productivity literature, particularly in nonparametric methods, cost reduction related methods are regarded as input oriented models. this paper presents a supply chain management (scm) model in which purchasing iron ore and coke from different resources, along with production and distribution of st...

The energy system in a modern integrated steel plant is a complicated network of units exchanging energy and matter with each other. System studies using process integration tools are important to avoid sub-optimization. At the steel plant in Luleå such studies have been carried out using a MILP-based mathematical programming tool (reMIND), mainly because of its inherent flexibility for handlin...

The logistic processes in most steel producing plants are very complex. To assist the decision makers in steel producing plants, Incontrol Enterprise Dynamics have developed for and in cooperation with SMS Demag in Germany, a simulator that can be used to rapidly model any steel plant. The Steel Plant Simulator has been built using the software package Enterprise Dynamics® and allows for rapid ...

During continuous casting, especially of modern steel grades or at higher casting velocities, undesired oscillating disturbances may occur, which strongly impair the quality of the final product, or even lead to costly plant downtime. In this paper, both a novel model based explanation of these level oscillations in terms of unstable internal feedback and delay time, as well as a corresponding ...

1 The high cost of empirical investigation in an operating steel plant makes it prudent to use all available tools in designing, troubleshooting and optimizing the process. Physical modeling, such as using water to simulate molten steel, enables significant insights into the flow behavior of liquid steel processes. The complexity of the continuous casting process and the phenomena which govern ...

1 Introduction: Hierarchical and modular representation of a timed Petri net model of steel plant

In this paper, by using the data of steel melting plant which contains major non-linear load i.e., induction furnace, we modeled such a system, which contains three 12-tons induction furnace in PSCAD software and simulated for three different operating conditions & studied harmonic pattern. Keywords—Induction Melting Furnace;Steel Melting Shop;Harmonics Analysis;Power Quality.
