Abstract
1. Manufacturing process for a silicosis and iron-free blast material for surface treatment, in particular of Austenitic steels, with a maximum grain size of 0.5 mm, made of crushed smelter slag granulate from hard coal combustion, characterized by crushing of the smelter slag granulate to the desired size before the raw material (with a maximum total iron content of approximately 7 % by weight, primarily occuring as iron silicate and iron aluminate) undergoes magnetic separation, resulting in a maximum metallic iron content of 0.1 % by weight.
