METHOD FOR PRODUCING BURDEN FROM IRON BASED POWDERS

摘要

powder metallurgy. SUBSTANCE: method involves introducing binder into powder; mixing components and forming briquettes. Binder is waste sulfuric acid solution with concentration of 0.5-5%. Method allows briquetted burden to be obtained from waste powdered cast iron and steel shots. EFFECT: increased efficiency and improved mechanical properties and chemical composition useful for manufacture of cast iron shots. 2 tbl, 2 ex
