Induction　heating　technology　has　been　extensively　applied　in　many　industrial　processes.　The　experimental　system　of　electromagnetic　induction　heating　molten　salt　is　designed　and　built　in　this　study;　the　molten　salt　electromagnetic　induction-heating　unit　is　developed.　The　simulation　results　and　the　experimental　data　are　in　good　agreement.　The　effect　of　molten　salt　inlet　temperature,　coil　current,　induction　heater　material　and　molten　salt　velocity　are　comparatively　studied.　The　results　show　that　the　molten　salt　outlet　temperature　increases　with　the　increasing　of　coil　current　and　decreases　with　the　increasing　of　molten　salt　velocity　under　same　heating　power.　The　heat　absorption　power　of　molten　salt　increases　with　the　increasing　of　molten　salt　inlet　temperature.　The　maximum　molten　salt　heat-absorption　power　in　carbon　steel　condition　is　significantly　23.39%　higher　than　that　of　stainless　steel　conditions.　Meanwhile,　the　maximum　heating　efficiency　of　molten　salt　in　carbon　steel　conditions　is　16.7%　higher　than　that　of　stainless　steel.　The　maximum　overall　heat　utilizing　efficiency　atT(s-i)=　292　degrees　C　under　different　working　conditions　is　90.12%,　which　is　3.38%　higher　than　that　atT(s-i)=　200　degrees　C.
