Alloyed Steel Wastes Utilization

Alloyed steel chips and swarf formed during metal processing are looked upon as additional raw material In metallurgycal production. The manuscript presents some new methods for steel waste chips and swarf cleaning. One of them Is swarf and steel chips cleaning In ethylene tetrachloride with ultrasonic assistance and following, solvent regeneration. Thermal cleaning of waste chips and swarf provides exit gas products utilization. Catalyst Influence of metal surface on the process of thermal decomposition of liquid hydrocarbons during cleaning process has been studied. It has been our experience that the efficiency of metal waste cleaning technique depends on the storage time of the swarf. Waste chips and swarf cleaning procedures presented in the manuscript have been proved economically advantageous and environmentally appropriate.
