Translated title of the contribution: Problems of downgrading of scrap quality

Research output: Contribution to journalArticlepeer-review


Problems of downgrading of scrap quality, separation and processing before smelting in foundry practice are considered in the present article. Most of scrap-processing companies currently use visual estimation instead of modern equipment for rapid analisys. This factor in many cases becomes an obstacle for quality steel and pig-iron scrap separation and leads to accumulation of detrimental impurities, especially non-ferrous metals such as copper, tin et. al. in iron-carbon melt. A sophisticated analysis of sources of non-ferrous metals pick-up by iron-carbon melt from different charge materials is made and several technical solutions for the problem are proposed.
