抄録

Sponge iron powder was prepared by reducing purified pyrites cinder with hydrogen which was obtained by removing As, Cu, Zn and silicate etc. from pyrites ore. The sponge iron was highly pure and its specific surface area was larger because of its porous structure than sponge iron ordinally used. The application of thus obtained iron powder for powder metallurgy, especially direct rolling to form thin sheet, was studied. Microscopic structure, magnetic and mechanical properties of the sheet were investigated. As for the magnetic property, average 6, 000 of maximum permeability and average 0.90 Oe of coercive force were observed. As for mechanical property, average 74 of Vickers hardness, approx. 20-24kg/mm2 of tensile strength were obtained and deep drawing was excellent.
