Steelmaking processes consume a lot of energy and materials, therefore researchers are constantly looking for new ways of reducing the consumption of resources in the production processes. The main purpose of the article is to present abiotic resource depletion the in steel production in the case of integrated steelmaking route in Poland and its role in life cycle assessment. There are differen...

these days, limited energy resources, and also the cost of investment in new and renewable energy is very costly and uneconomical. in the industrial sector, especially energy-intensive industries such as steel, finding appropriate solutions to update the technology, production and reduce energy consumption in this sector is very important. the main aim of this study is the identification and ra...

This paper describes the adsorption of two organic (acetic and citric) acids on the blast furnace sludge, a representative by-product of the steelmaking industry. By PIXE, XRD, BET and SEM methods, it was shown that blast furnace sludge is a complex heterogeneous material with a specific surface area of s = 31.46 m g, composed mainly of amorphous phase (w = 76.2 %), calcite (w = 9.9 %), magneti...

The amount of CO2 emissions, water and electricity consumption, soil exploitation the main steel production routes (integrated cycle, scrap recycling, direct reduction) are analyzed applying three possible future scenarios: use carbon capture storage (CCS); green hydrogen in substitution natural gas; biomethane. Using actual process data theoretical assumptions, emissions consumptions whole cyc...

In modern steelmaking the duration of a working campaign for a blast furnace is related to the life of the crucible. Adding titanium oxide has been a frequent practice in the operation routines for modern blast furnaces, seeking the protection of the crucible walls, independently from its physical or chemical characteristics. These practices, as conventional operation of iron and steelmaking in...

Steelmaking in the electric arc furnace (EAF), either scrap-based or based on hydrogen direct reduced iron, will future contribute substantially to reduction of CO2 emissions iron and steel industry. However, there still be need introduce carbon into EAF process carburize create foaming slag improve energy efficiency melting process. So, reach emission goals set around world, it necessary subst...

Recycling phosphorus from phosphorus-containing wastes and byproducts is a promising secondary resource. Steelmaking slag generated in large quantities as byproduct of the iron steelmaking industry, contains that could be possible Phosphorus can extracted into aqueous solution; however, concentration generally lower than other elements, causing problem for recovery. In this study, bipolar membr...
