摘　　要：对等离子熔炼Fe-PGM合金物料的取制样方法进行了研究。物料经破碎至40目,混匀,均分为12个网格,每个网格钎取20 g样品,混合得到240 g大样,大样进一步研磨至150目得到分析样品。经物料均匀性检验和取样代表性分析,表明取样方法可满足物料取样和分析要求。A sample preparation and sampling method for analysis of plasma smelting Fe-PGM alloy was studied. The alloy was crushed to 40 mesh size, homogeneously mixed, divided into 12 grids. From every grid, a sample of 20 g was taken, and then mixed together to produce a large sample weighing 240 g which was subjected to the fine grind process to give an analytical sample. Homogeneity and representativeness tests show that the sampling method meets the analytical requirements for Fe-PGM alloy.
