Environmental Impact Evaluation for effective resource Management in EAF Steelmaking

, 2017
The assessment of the environmental impact of steelworks has been intensively discussed in the last decades, especially focusing on CO2 emissions and energy consumptions. Nowadays an increasing attention is paid to the evaluation of the resource efficiency and overall environmental impact; some work groups also focused on the development of various eco-

Waste management in steelmaking by EAF route

Serbian Journal of Engineering Management, 2022
Electric arc furnace slag (EAFS) and electric arc furnace dust (EAFD) are the waste materials from the steel production by EAF route which implies remelting of iron and steel scrap in electric arc furnaces (EAF). In recent years, special attention is paid on the valorisation of EAFS and EAFD since disposing the both may cause negative impacts on the ...

Slag foaming estimation in the electric arc furnace using machine learning based long short-term memory networks

Journal of Materials Research and Technology, 2021
Slag foaming is a key factor in terms of quality and productivity in the electric arc furnace (EAF) steelmaking process. Optimal control of slag foaming is required, but is difficult due to the absence of practical on-line measuring methods and the broad

Steelmaking. Development of Dioxins Removal Systems for EAF.

DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1999
We have studied two types of dioxins removal systems for EAF. One of those systems consists of double bag houses and another system has the activated carbon injection system besides double bag houses. We have made about one 50th scale equipment and fundamental experiments have been carried out with small EAF.
