Processing Slag From Ferroalloy Production

A new process to recycle metallurgical slag My Droll

Aug 11 2021 The obtaining clinker from ladle slag is a more complex technological task than obtaining pig iron from an electric furnace. Therefore the researchers first calculated the conditions necessary for the production of clinker. These are the chemical composition of the processed mixture charge and the temperature range.
