Development of parameters of slags from ladle metallurgy during their primary treatment

Popis výsledku v původním jazyce

Slags from steel production represent a significant high volume waste. More than 0.5 mil tons of slags is produced in steelmaking in The Czech Republic per year. A considerable amount of these waste products is uselessly deposited. Knowledge of slag properties leads to higher rate of its use. A high variability in quality of produced steel, as well as various type of aggregates, where the steel is produced in, contribute to fact, that steel slags show varied parameters. An introduced paper tries to describe development of the chemical and the phase composition of slag from a ladle metallurgy in process of their primary treatment with regard to possibilities of further material use of this type of slag. An essential discovered fact is that, the slag taken from metallurgical ladle shows different parameters as the same slag, which is taken in specific points of its primary treatment. It was discovered, that slag becoming from melting aggregate changes in the process of its following treatment. This change is obvious in a chemical and a phase composition of slag. The changes of a chemical composition are caused by a contamination of slag, particularly by a steel contamination. The changes in phase composition of a slag are the result of a thermal history of slag. (C) 2018 Czech Environment Management Center. All rights reserved.
