A　casting　granulated　metal　equipment　by　a　short　flow　was　developed,　which　is　comprised　of　pre-heating　chamber,　heating　furnace,　ceramic　pipe　used　to　transport　the　molten　metal,　the　holding　furnace,　the　drip　nozzle　and　the　cooling　tank　etc.　The　equipment　can　accomplish　preheating　the　ingot,　melting,　holding　temperature　and　the　polluting　at　the　same　time.　The　preheating　temperature　of　ingot　is　100-120　degrees　C.　After　the　ingot　is　melted,　the　molten　metal　is　transported　to　the　holding　furnace　from　the　melting　furnace　by　ceramic　pipe,　and　the　temperature　in　the　holding　furnace　is　25-28　degrees　C　above　the　melting　point　of　metal.　And　the　dwell　time　of　granulated　metal　is　10-18　seconds　in　the　cooling　water　box.　Finally　the　granulated　metal　is　directly　delivered　to　the　packing　box　by　the　bucket　elevator.　The　granulated　metal　produced　by　a　short　flow　has　lower　energy　consumption　and　higher　efficiency,　and　the　energy　consumption　is　15-20%　lower　than　that　of　the　common　flow.
