Mukugadzirwa kweDuctile Iron (inozivikanwawo seDuctile Iron), kushandiswa kwemhando yepamusoro carburizers kwakakosha kuti uwane izvo zvinodiwa zvechigadzirwa chekupedzisira.A inowanzoshandiswa recarburizer isgraphite petroleum coke (GPC), iyo inogadzirwa kubva petroleum coke kuburikidza nepamusoro-tembiricha yekupisa.

Paunosarudza recarburiser yekugadzira ductile iron, zvinhu zvakati wandei zvinofanirwa kutariswa.Chinonyanya kukosha pane izvi zvinhu zvakagadziriswa kabhoni yemukati, sarufa yemukati, madota emukati, inovhuvhuta nyaya yemukati, nitrogen yemukati uye hydrogen yemukati.

Fixed kabhoni yemukati iperesenti yekabhoni yasara mugraphite petroleum coke mushure mekupisa kwese nemadota.Iyo yakakwirira yakagadziriswa kabhoni yemukati, zviri nani iyo recarburiser iri pakuwedzera kabhoni yemukati musimbi yakanyungudutswa.graphite petroleum coke ine yakagadziriswa kabhoni yeinenge 98% inokurudzirwa kugadzirwa kweiyo ductile iron.

Sulfur itsvina yakajairika mugraphite petroleum coke uye kuvapo kwayo kunogona kukanganisa maitiro ekupedzisira e ductile iron.Saka, zvakakosha kusarudza graphite petroleum coke ine yakaderera sulfur content (kazhinji isingasviki 1%).

Madota ari muhuwandu hwezvinhu zvisingabatike zviri mugraphite petroleum coke.Yakakwira madota emukati inogadzira slag muchoto, iyo inowedzera mari uye inoderedza kushanda zvakanaka.Ichi ndicho chikonzero zvinokurudzirwa kushandisa graphite petroleum coke ine madota ari pasi pe 0.5%.

Chinhu chinoputika chinosanganisira chero magasi kana zvinwiwa zvinoburitswa kana graphite petroleum coke ichipisa.Yepamusoro inotenderera nyaya yemukati inoratidza kuti graphite petroleum coke inogona kuburitsa mamwe magasi, ayo anogona kugadzira porosity muchigadzirwa chekupedzisira.Saka, graphite petroleum coke ine volatile matter content isingasviki 1.5% inofanira kushandiswa.

Nitrogen content ndiyo imwe tsvina mu graphite petroleum coke iyo inofanira kuchengetwa yakaderera sezvo inogona kukanganisa mechanical properties ye nodular cast iron.graphite petroleum coke ine isingasviki 1.5% nitrogen yemukati yakanakira nodular cast iron kugadzirwa.

Chekupedzisira, hydrogen zvirimo ndechimwe chinhu chinofanira kutariswa pakusarudza kabhoni inosimudza nodular cast iron kugadzirwa.Yakakwira hydrogen mazinga anogona kukonzera kuwedzera brittleness uye kuderedzwa ductility.graphite petroleum coke ine hydrogen zviri pasi pe 0.5% inodiwa.

Muchidimbu, kugadzirwa kwenodular cast iron kunoda yakakwira-mhando kabhoni inosimudza inosangana nezvinodiwa zveyakagadziriswa kabhoni yemukati, sarufa yemukati, madota, zvinhu zvinoputika, nitrogen yemukati, uye hydrogen zvirimo.Kushandiswa kwegraphite petroleum coke inosangana nezvinodiwa izvi ichaita kuti kugadzirwa kwemhando yepamusoro nodular cast iron, inozivikanwawo seDuctil Iron kana SG iron.
