Abstract

An iron-silicon alloy containing from 14.25 to 25 per cent and preferably 15 to 18 per cent silicon is used in the form of shot or grit as an abrasive, particularly for cleaning articles, such as castings, made of brass, bronze, copper or stainless steel. The shot and grit may be made by melting ferro-silicon with pig iron and scrap steel and disintegrating a stream of the molten alloy by a jet of steam, water or compressed air in known manner. The product may contain small percentages of impurities such as carbon, manganese, sulphur and phosphorus.ALSO:An iron-silicon alloy in the form of shot or grit contains 14.25 to 25 per cent, and preferably 15 to 18 per cent silicon.
