Mhedzisiro yespheroidizer(nodularizer）pasimbi yakakandwa yakapetwa kaviri:
1，Nyika isingawanzo se nodulating agent yakanyungudutswa musimbi yakanyungudutswa ine simba rakasimba pakuumbwa kwecarbide.Iyo chinhu chinonzi antigraphitized.Zvisinei, kuwedzera hushoma hwepasi mu magnesium-based spheroidizer inogona kuwedzera zvakanyanya kunyunguduka kwekukanda. iron.Drekidza;Kana huwandu hwekuwedzera hwakakura, hutsika hwesimbi yakaumbwa huchavandudzwa.Chiitiko ichi chinoita sechinopokana hachisi chokwadi chinopokana.Iko nokuti nyika isingawanzowaniki ine simba rakasimba rekubatanidza nesarufa neokisijeni.
2, apo iyospheroidizerine zvinhu zvisingawanzoitiki zvepasi, sulfide yayo nemaokisi zvakadzikama, diki diki saizi, inonetsa kuyangarara musimbi yakanyungudutswa. Pamusoro pezvo, kusapindirana pakati pemakomponi aya uye graphite lattice idiki kwazvo uye inogona kushandiswa seyakasiyana-siyana precipitates graphite nuclei.Magnesium oxide MgO is a spheroidizing agent ine yakakwira kunyungudika, kugadzikana kwakanaka uye kushomeka kunyungudika musimbi yakanyungudutswa, asi kana saizi yechidimbu ichiti kurei zvishoma, inoyangarara kumusoro kuti ive scum, kana inogona kunge yakabatanidzwa kukanda kwekubatanidzwa kwe slag.
Nodulizer(ReMgSiFe), inopinda muropa iyo inogona kusimudzira kuumbwa kwe spheroidal graphite kubva kumagraphite zvimedu mumagadzirirwo ekugadzira.Inogona kukurudzira spheroidal graphite uye kuwedzera nhamba ye spheroidal graphite kuitira kuti maitiro avo emagetsi avandudzwe.Somugumisiro, iyo ductility uye kuoma kwezvigadzirwa zvakagadziridzwa kuitira kuti simba ravo nemabasa zvisimbiswe zvikuru.
Iyo inorema isingawanzo pasinodulersnakidzwa nekugona kwakasimba ne-anti-recession, anti-distortion uye anti-kupindira mukugadzira.Iyo magnesia yaro inodzorwa mukati me 0.6%.Iine yakagadzikana yepakutanga simbi yakanyungudutswa uye yakura nodulizing tekinoroji, iyo yakasara magnesium inogona kudzorwa zvakatsiga.
