Ferroalloy mugadziri anokupa yakadzama mugove wese kushandiswa kwe spheroidizer/nodularizer

Mhedzisiro yespheroidizer(nodularizer)pasimbi yakakandwa yakapetwa kaviri:

1,Nyika isingawanzo se nodulating agent yakanyungudutswa musimbi yakanyungudutswa ine simba rakasimba pakuumbwa kwecarbide.Iri chinhu che antigraphitized.Zvisinei, kuwedzera hushoma hwepasi mu magnesium-based spheroidizer inogona kuwedzera zvakanyanya kunyunguduka kwekukanda. iron.Deredzai;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 iyospheroidizer ine zvisingawanzo zvinhu zvepasi, sulfide yayo uye okisidhi yakagadzikana kwazvo, diki diki saizi, inonetsa kuyangarara musimbi yakanyunguduka.Pamusoro pezvo, kusawirirana pakati pezvisanganiswa izvi 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 kuti inogona kubatanidzwa mune kukanda kwekubatanidzwa kwe slag.

Nodulizer (ReMgSiFe),chinhu chinopindwa muropa chinogona 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 munzira yekugadzira.Iyo magnesia inodzorwa mukati me 0.6%.Iine yakagadzikana yepakutanga simbi yakanyungudutswa uye yakura nodulizing tekinoroji, iyo yakasara magnesium inogona kudzorwa zvakatsiga.
