抄録

The mechanical and physical properties of strips produced by the powder rolling method were investigated with three kinds of domestic iron powders, such as nitriding-process iron powder, sponge iron powder, and mill-scale reduced iron powder. In addition, the effect of particle size on the above properties was also investigated.<BR>As reported in previous papers on Höganäs sponge iron powder, with the increasing powder feed in powder rolling, the rolling load, thickness and apparent density of green strip were increased and the various properties of sintered and cold rolled strips were improved. The rolling load and thickness of green strip were more affected by the flowability more than the particle size of powder. The better mechanical and physical properties of sintered and cold rolled strips were obtained in the order of purity of powder. The effect of particle size of powder on the properties of cold rolled strip was observed: With the decrease in particle size, the elongation increased, but, on the contrary, the larger the particle size, the better the magnetic properties of cold rolled strip.
