The steel-making and continuous casting system (SCCS) is the bottleneck in the iron and steel production, SCCS often involve various uncertainties such as the emergency customer orders, inaccurate estimate of ingredient components, the unpredictable machine breakdown or the inaccurate estimate of processing time. How to consider such uncertainties to build a better schedule in a limited time by...

To remain competitive in the global marketplace, Bethlehem Steel Corporation (BSC) was looking for opportunities to reduce energy costs while improving overall steel-making system performance at its Burns Harbor facility in northwest Indiana. By installing a variable frequency drive (VFD), and making equipment modifications to the induced draft fans that remove gases from one of the facility’s ...

With the advancements of robotic technologies, the industrial environments are adopting more and more aspects of automation to enhance product quality and accuracy and to reduce product cost. One of these aspects is the use of Automated Guided Vehicle (AGV) which is gaining importance in industrial logistics and transportation systems. Automated Guided Vehicles are the essential parts of all au...

Iron and steel industry is a crucial basic section for most of the industrial activities. This industry provides the primary materials for construction, automobile, machinery and many other businesses. Furthermore, the iron and steel manufacturing is highly energy consuming. The influence of an efficient process control on the cost and energy reduction and environmental effects in iron and stee...

Background: A high prevalence of noise-induced hearing loss (NIHL) is observed amongst employees in the steel manufacturing industry. Objective: To determine the prevalence of NIHL and current noise abatement techniques implemented at a steel manufacturing plant. Methods: Structured questionnaires were completed by permanent employees at a steel-manufacturing plant for the purpose of collecting...

grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °c) during the normal operation of the process. in this study, different samples from several sections ofused grate bars with apparent defects were selec...

Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product pellets and plant equipment, as well as the cost of the plants....

A modular DCLL blanket is selected as the reference concept in the ARIES-CS power plant study. This concept is characterized by the following features: 1. Eutectic lead lithium alloy Pb-17Li serving as breeder and coolant (“self-cooled breeding zone”); 2. Helium-cooled FW and blanket structure made of the MF82H Reduced Activation Ferritic Steel (RAFS); 3. Flow channel inserts (FCI) made of SiCc...

during the last years, several exceedances of pm10 and benzo(a)pyrene limit values exceedances were recorded in taranto, a city in southern italy included in so-called areas at high risk of environmental crisis because of the presence of a heavy industrial district including the largest steel factory in europe. a study of these critical pollution events showed a close correlation with the wind ...
