Yintoni i-Sintered metal parts:
Amalungu esinyithi enziwe nge-sintered ayenziwa kusetyenziswa aubuchule besinyithi somgubo ebizwa ngokuba sintering. Kule ndlela, i-powder yensimbi ixinzelelwe kwisimo esichanekileyo, kwaye emva koko ubushushu busetyenziselwa ukudibanisa iincinci zetsimbi ngaphakathi kwento eyenziwe, eyenza ukuba igcine imo yayo entsha.Sinteringingasetyenziselwa ukuvelisa uluhlu olubanzi lweentlobo zenxalenye yentsimbi kwaye iyahambelana neentsimbi ezininzi ezahlukeneyo kunye ne-alloys.
JIEHUANGI-Sintered Metals ziingcali kwiinkqubo zokusika ezijika isinyithi somgubo zibe yimveliso yentsimbi ehlala ixesha elide, ethembekileyo. Funda ngakumbi malunga nenkqubo yokufaka isinyithi kunye nendlela enokunceda ngayo isicelo sakho ngokufunda.
Yintoni inkqubo ye-sintering:
Inkqubo ye-Sintering kukulungiselela umgubo wentsimbi, i-flux, i-fuel kunye ne-substitutes ngokweemfuno ze-blast furnace smelting, ngokomlinganiselo othile wokuxutywa, ukuxuba, ukongeza ukuthambisa kwamanzi. I-regranulation, i-ignilation yokusabalalisa, ngoncedo lwe-fan, ukuze phantsi kwesenzo sobushushu obuthile obuphezulu, umphezulu we-iron ore powder ukuthamba kunye nokunyibilika, ukuvelisa isigaba esithile solwelo, kunye namanye amasuntswana ore ore anyibilikayo, emva kokupholisa, isigaba solwelo siya kunamathela amasuntswana omgubo wezimbiwa kwiibhloko le nkqubo ye-sintering.
Inkqubo esisiseko sintering
ukucofa umgubo → ukutshaja (ukulungiselela phambi kokulayisha kunye nokuntywila) → ukutshisa (ubushushu bangaphambili, ugcino lobushushu kunye nokupholisa) → ukuphuma → umzimba otshisiweyo
