Present Status and Future Development of Domestic Electric Arc Steel Production

Teshugang, 2009
The output of domestic arc furnace steel increased year by year which was near to 50 million ton in 2007. The number of large electric arc furnace increased obviously,in 2007 the output of ≥ 50 t electric arc furnaces was about 83.5% of total electric ...

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

A Novel Approach to Energy Management in Electric Steelworks

steel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

IRON ORE SINTER PRODUCTION USING ELECTRIC ARC FURNACE DUST AS RAW MATERIAL [PDF]

Tecnologia em Metalurgia, Materiais e Mineração, 2013
The steel production through Electric Arc Furnaces (EAF) generates approximately 15% to 20% of Electric Arc Furnace Dust (EAFD). This waste is considered dangerous due to the presence of metals as lead and cadmium that leach in contact with water ...

Decreasing the Environmental Impact of the Electric Steelmaking Route Through Advanced Modelling Techniques

steel research international, EarlyView.
Ensemble models are adopted to estimate the sterile content of scraps arriving to the scrap yard. Feed‐forward neural networks are exploited to estimate steel composition and temperature after Ladle furnace. The models are validated on data from two steelworks very satisfactory results and are inherently transferable to other steelworks, as they are ...

INVESTIGATION OF THE ROLE OF LIME UNDER SLAGGING AND INERT-GAS SECONDARY STEEL REFINING

Advanced Engineering Research, 2013
It is shown that the creation of such technologies is caused by the necessity of making standard high-quality steel in composition and temperature. The secondary steel refining provides these conditions and, consequently, the efficient operation of the ...
