中文摘要：

选用Nd-Pr,Fe-B合金,纯铁以及海绵锆为原料,按一定的比例,采用低氧（真空、Ar气）速凝工艺,在1400℃-1450℃,600mm×500mm规格铜轮,v=1m/s-2m/s的冷却强度下,制备厚度为0.2mm-0.45mm的（Nd,Pr）-Fe-B稀土永磁母合金薄片,并对产物通过XRD,SEM进行表征。采用一定工艺将合金制备成烧结永磁体,通过对退磁曲线分析,证明可获得性能理想的（Nd,Pr）-Fe-B产品。

英文摘要：

In this paper,（Nd,Pr）FeB alloy was prepared with alloys of Nd-Pr and Fe-B,sponge iron and zirconium as raw materials by hypoxia-strip casting method in temperature of 1400℃～1450℃ and cooling speed of 1m/s～2m/s.The resulted alloy was characterized with XRD and SEM.Sinterd permanent magnet prepared from the precusion alloy showed ideal performances through demagnetization curve.
