摘要：

Influence　of　rotational　speed　of　electromagnetic　centrifugal　casting　machine　on　microstructure　and　properties　of　high　carbon　high　speed　steel　(HC-HSS)　was　investigated　under　the　condition　of　the　magnetic　intensity　of　0.1　T.　The　results　show　that　the　microstructure　of　the　steel　are　obviously　refined.　Meantime,　the　coarse　carbides　(VC)　along　grain　boundary　is　changed　into　small　particles.　After　heat　treatment,　hardness,　impact　toughness　and　wear　resistance　of　the　steel　also　increase　as　centrifugal　speed　increases　from　600　r/min　to　1370　r/min.
