METAL POWDERS OBTAINED FROM RESIDUE OF MATERIAL REMOVAL PROCESSES ON IRON PARTS PRODUCED BY CHILL CASTING

摘要

A method for the production of a pre-alloyed metal residue powder is described, the method comprises the steps of: i) grinding a chill cast iron body using a grinding wheel together with oil and a cooling fluid to produce a grinding residue; ii) washing and residues to remove the oil and the cooling fluid; iii) drying the residues; and, iv) subjecting the residues to mechanical agitation to reduce particle agglomeration.
