Steel Dynamics, Inc. is a steel producer based in Fort Wayne, Indiana and the fifth largest producer of carbon steel products in United States. Over sixty percent of the company’s steel shipments are flat-rolled sheet steel and the remainder is "long products" and fabricated products. SDI is among the most profitable American steel companies in terms of profit margins and operating profit per ton.SDI was founded in 1993 and began production at its Butler, Indiana, Flat Roll Mill in 1996. The Flat Roll Division’s finishing facilities at Butler and at Jeffersonville, Indiana, produce pickled, cold-rolled, galvanized, and painted flat-roll steel.In 2007 SDI acquired The Techs, three galvanizing plants in Pittsburgh that coat flat-rolled steel.On July 21, 2014, SDI announced the acquisition of Severstal Columbus, LLC from OAO Severstal for 1.625 billion. The acquisition expands Steel Dynamics' annual steel shipping capacity to 11.0 million tons, representing an approximate 40 percent increase. The additional exposure to the high-growth OCTG and automotive segments complements Steel Dynamics' market offerings. Commissioned in 2007, Columbus is one of the only North American flat roll mills to have 76 inch wide hot roll, 74 inch wide cold roll, and 72 inch wide galvanized sheet capabilities. These and other production capabilities will broaden Steel Dynamics' product portfolio with regard to width, gauge and strength and enhance the Company's position as a leading North American steel producer.

World Steel Dynamics (WSD), a leading steel information service from Englewood Cliffs, New Jersey, US, presents a report about the growth of steel mills in Japan, US, and other countries. The WSD's steel experience, steel database and availability of steel statistics are the principles for performing such steel forecasts, studies, and analysis for international clients. It seeks to understand how the 'pricing power' of steel companies from around the world will be impacted by changes in the steel industry's structure. The report states that Japanese steel mills are in the process of making significant improvement in cost position, despite lower raw material prices and a weaker Japanese yen. Experts suggest that leading domestic steel mills will be competitive with the Russians in many markets if the yen weakens to about 110 per US dollar, as these mills are located at deepwater ports.

Before the upgrade there were a lot of resources being consumed by this equipment. With the improvements that have been made these resources can be utilized in other areas of the shop. The numbers show the dependability of the equipment increased. Down time, and maintenance cost decreased. Uniform product movement. Excellent cylinder, pump, and oil life. This project was not completed over night but all goals were met. Happiest of all the operators who can now produce more steel.

This paper illustrates how systems requirements (i.e.; safety) are decomposed to define manufacturing process requirements and design. Steelmaking is an energy intensive process; utilizing vast amounts of electricity, oxygen, and natural gas to liquefy scrap steel. While the electric arc furnace process is used extensively around the world to melt steel, it is inefficient. Hot gases are lost to fume collection systems and not reused in other parts of the process. Unknown water leaks inside a furnace can potentially result in catastrophic explosions which can injure personnel or damage equipment. Carbon monoxide (CO), the largest gas by product of steelmaking, has caused several large scale explosions globally resulting in large repair bills. A system to not only detect gases present in the gas steam exiting the furnace but to quantify the amounts being produced can lead to ensuring the furnaces are safer for employees to work around. This paper will break down the decision process in selecting the hybrid probe-laser off-gas system by means of axiomatic design decomposition at an American mini-mill located in Butler, Indiana using the Collective System Design (CSD) methodology utilized at IPFW Center of Excellence in Systems Engineering. © 2015 The Authors.

Caster No. 1 cross-transfer pusher hydraulic system experienced a high number of cylinder failures, which caused lost production time, high maintenance costs in repairs, and high costs of hydraulic oil loss and replenishment requirements. A systematic approach to optimizing the cylinder reliability and life was executed and included advanced instrumentation, technology, and engineered upgrades to the equipment and system.
