Abstract

First, the sintering and cold rolling conditions were determined with rolled strip from Höganäs iron powders. Second, the effect of various powder rolling factors on the physical and mechanical properties of sintered and cold rolled strips were investigated.<BR>The similar tendency in effect of powder rolling factors on the properties of sintered strip was observed. That is, with decrease of roll gap and rolling speed and with increase of powder feed, the apparent density, tensile properties were increased and electrical resistivity was decreased. In the case of cold rolled strips, the effect of powder rolloing factors was observed on the elongation alone. With increase of powder roll load the elongation was increased. The various properties of cold rolled strips produced by powder rolling method are compared favorably with those of conventionally produced strips.
