Obtaining of strong chromium pellets with the use of a ferrosilicon-calcium binder

The article presents the results of research on the synthesis of strong chrome pellets based on concentrates obtained by enrichment of chrome sludge. To obtain strong fired pellets from the concentrates, it is proposed to use a ferrosilico- calcium reagent as a binder, which makes it possible to inc...
