Mhedzisiro yespheroidizer(nodularizer）pasimbi yakakandwa yakapetwa kaviri:

1, Kashoma pasi se nodulating agent yakanyungudutswa musimbi yakanyungudutswa ine simba rakasimba pakuumbwa kwecarbide.Iyo antigraphitized element.Zvisinei, kuwedzera chidimbu chepasi risingawanzo mu magnesium-based spheroidizer inogona kuwedzera zvakanyanya kunyungudika 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 zvisingawanzo zvinhu zvepasi, sulfide yayo uye okisidhi yakagadzikana kwazvo, diki diki saizi, inonetsa kuyangarara musimbi yakanyungudutswa. Uyezve, kusapindirana pakati pemakomponi aya uye graphite lattice idiki kwazvo uye inogona kushandiswa seyakasiyana 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 kuti inogona kunge yakabatanidzwa kukanda kwekubatanidzwa kwe slag.

Nodulizer(ReMgSiFe),inopindwa 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 yakakura nodulizing tekinoroji, iyo yakasara magnesium inogona kudzorwa zvakatsiga.
