Scheduling High-Grade Steelmaking
The paper describes a scheduling system for a high-grade steel making plant. Because very specialized steel grades are produced the variety of the chemical analysis of the heats is very high and the lot sizes are small. One of the most constraining factors in the production is the infiltration of chemical elements between consecutive heats in the electric arc furnace. To find a schedule that vi...
متن کاملLance-Adams Syndrome
Lance-Adams syndrome (LAS) is a rare complication of successful cardiopulmonary resuscitation and is often accompanied by action myoclonus. LAS is seen in patients who have undergone a cardiorespiratory arrest, later regained consciousness, and then developed myoclonus days or weeks after the event. Less than 150 cases of LAS have been reported in the worldwide medical literature. Here, we pres...
متن کاملSteelmaking and Casting
Thin slab casting and rolling was originally developed as a low cost alternative to a conventional casting and rolling process route. However, due to the technological restrictions of the first generation plants, only limited quality and productivity goals could be achieved, questioning its further application to more advanced applications. This paper describes the original contributions that D...
متن کاملDistributed Lance-William Clustering Algorithm
One important tool is the optimal clustering of data into useful categories. Dividing similar objects into a smaller number of clusters is of importance in many applications. These include search engines, monitoring of academic performance, biology and wireless networks. We first discuss a number of clustering methods. We present a parallel algorithm for the efficient clustering of objects into...
متن کاملChapter 9 - Oxygen Steelmaking Processes
The oxygen steelmaking process rapidly refines a charge of molten pig iron and ambient scrap into steel of a desired carbon and temperature using high purity oxygen. Steel is made in discrete batches called heats. The furnace or converter is a barrel shaped, open topped, refractory lined vessel that can rotate on a horizontal trunnion axis. The basic operational steps of the process (BOF) are s...
