Republic Steel, a provider of special bar quality steel, has started hot commissioning of its new electric arc
furnace in Lorain.
At the new electrical steel works, Siemens is projecting and delivering the mechanical and electrical equipment for a new electric arc
furnace with a tapping weight of 110 tons, a 110-ton ladle furnace, a vacuum degassing plant and the alloying and additive systems.
The process produces electric arc
furnace dust (EAFD), a hazardous material containing lead and cadmium.
The company said the electric arc
furnace with the COSS system was developed by Fuchs Technology of Germany.
This is because the energy generated by an electric arc
is directly proportional to the arc current and the arc duration"
Outotec (Helsinki:OTE1V), which is engaged in minerals processing and metallurgical technologies, declared on 4 May that it has entered into an agreement with Finland-based Real Time Systems Oy to cooperation in the development of a new-generation measuring and regulating system for electric arc
furnaces, which are used by steel mills in the production of steel from steel scrap.
The company, which will employ 43 people, will process electric arc
furnace dust from the Nucor Hickman and Nucor Yamato steel plants in Mississippi County, converting it into marketable products used primarily in the metals industry.
A EUROPEAN Bank for Reconstruction and Development (EBRD) US$85 million loan to ISTIL Ukraine, will help the Ukraine's only modern mini-steel mill using an electric arc
furnace and continuous casting technology to raise Euro 3 million in Kyoto Protocol carbon credit sales.
Abstract: Electric arc
furnaces (EAFs) are commonly used in steelmaking and in smelting of nonferrous metals.
Whether they join the consolidation craze or focus on niche markets, many of the electric arc
furnace operations in the United States are facing growing pressure from consolidators.
Each of the six ladles of steel was melted in a single, 95-ton electric arc
furnace and then subsequently treated and kept hot in rotation in either the vacuum arc degassing unit or the similar vacuum oxygen decarburization unit," Marston said.
Even though much of Chinas steel is produced with blast furnaces, rather than 100-percent-scrap-consuming electric arc
furnaces, raw materials buyers representing Chinas mills have spanned the globe this decade seeking melting units whether iron ore, pig iron or scrap for their new furnaces.
