The purpose of this project is to obtain silicon-iron alloy sheets having the {110}<001> grain texture and low iron loss by cold-rolling and annealing rapidly quenched silicon-iron ribbon containing 4-6 wt% silicon. As a result, we succeeded to realize the sheets having good {110}<001> texture by the rolling with high reduction rate per pass. These sheets have excellent magnetic properties such as high magnetic induction B8 of 1.86, low coercive force of 6.0 A/m and low iron losses 0.22 W/kg (W_<12.5/50> 0.32 W/kg (W_<15/50>) and 0.51 W/kg (W_<17/50>).

本项目的目的是通过冷轧和退火含4-6wt%硅的快速淬火硅铁带，获得具有{110}&lt；001&>晶织构和低铁损的硅铁合金薄板。结果表明，采用单道次压下率高的轧制工艺，成功地获得了具有良好的{110}&lt；001&gt；织构的板材。这些薄板具有优异的磁性能，如高磁感应强度B8为1.86，低矫顽力为6.0A/m，低铁损为0.22W/kg(W_&lt；12.5/50&gt；0.32W/kg)和0.51W/kg(W_&lt；17/50&gt；)。
