Chemical baling of oily cast iron turnings and use of bales to substitute expensive and scarce scrapes

Abstract

The results of the research are presented as the technology of smelting cast iron using iron-containing substances with organic pollutants as a charge material. Iron- and carbon- containing substances are introduced into the melt as stable components of bales which are not damaged during transportation. Bales are formed under low pressure from iron- containing substances with organic pollutants which do not undergo the preliminary treatment. When bales are produced, cheap materials are used as binders. Binders are formed at the expense of chemical hardening and oxidation of organic pollutants to less environmentally harmful compounds, and refining the melt from contaminants. The composition of bales provides the reduction of iron from its oxide compounds.
