Cr12MoV yotentha yozungulira zitsulo zozungulira

Chitsulo cha Cr12MoV chimakhala cholimba kwambiri, ndipo omwe ali ndi gawo la 300 mpaka 400 mm kapena kuchepera amatha kuzimitsidwa.
Imatha kukhalabe olimba komanso kuvala kukana pa 300 ～ 400 ℃, kulimba kwake ndikwapamwamba kuposa chitsulo cha Cr12, ndipo kusintha kwa voliyumu ndikochepa pakuzimitsa. Itha kugwiritsidwa ntchito popanga zisankho zosiyanasiyana ndi zida zokhala ndi magawo akulu akulu, mawonekedwe ovuta, komanso kupirira katundu wambiri. Mwachitsanzo, nkhonya imafa ndi mawonekedwe ovuta, oyika pamafa ovuta, chojambula chakuya chachitsulo chimafa, kujambula waya kumafa, mbale ya waya ya ulusi, kuzizira kozizira kumafa, lumo lodulira ozizira, macheka ozungulira, zida zokhazikika, zida zoyezera, etc.
Chitsulo cha Cr12MoV ndi chitsulo cha carbon, high-molybdenum lysic chitsulo. Mpweya wake ndiwotsika kwambiri kuposa wachitsulo wa Crl2, ndipo umawonjezeredwa ndi zinthu za molybdenum ndi vanadium, zomwe zimathandizira kwambiri kutenthetsa kwachitsulo, kulimba komanso kugawa kwa carbide. Chitsulocho chimakhala ndi kukana kwamphamvu kwambiri, kuuma, kuuma, kulimba, kukhazikika kwamafuta, mphamvu zopondereza, komanso mapindikidwe ang'onoang'ono, magwiridwe antchito abwino kwambiri komanso kusinthasintha kwakukulu. Kutentha kofewetsa kutentha ndi 520 ℃. Kukula kodulidwa kuli pansi pa 4mm ndipo kumatha kuumitsidwa kwathunthu. Kukaniza kuvala kwa chitsulo ichi ndi 3 ~ 4 nthawi zambiri kuposa chitsulo chochepa chachitsulo, ndipo voliyumu yozimitsa ndi yaying'ono. Kuwumitsa kuya: mafuta kuzimitsa 200 ~ 300mm.
Panthawi ya crystallization, chiwerengero chachikulu cha eutectic white carbides chimapangidwa (kagawo kakang'ono ka carbonized pafupifupi 20%, ndipo kutentha kwa eutectic ndi pafupifupi 1150 ° C). Ma carbides awa ndi olimba kwambiri komanso osasunthika. Ngakhale ma carbides amathyoledwa pamlingo wina pambuyo pa kugubuduza kwa billet, ma carbides amagawidwa m'magulu, ma slabs, midadada, ndi milu motsatira njira yogubuduza, ndipo kuchuluka kwa tsankho kumawonjezeka ndi kukula kwa chitsulo.

Chithandizo cha kutentha kwa Cr12MoV Alloy Steel

spheroidizing annealing: 860 ℃ X 2h kuzirala kwa ng'anjo mpaka 750 ℃ ​​ndiyeno kuzirala kwa ng'anjo mpaka 500-550 ℃, chotsani kunja ndi kuziziritsa mpweya.

Kuzimitsidwa + kupsa mtima: 1100 ℃ X 20min sitepe kuzimitsa + 700 ℃ X 1h kutentha, chotsani kunja ndi kuziziritsa mpweya

Kuzimitsa: 1030 ℃ X 40min mafuta kuzimitsa (800 ℃ preheating, vacuum 2.5 pa) Kutentha: 250 ℃ X 1h

Kugwiritsa ntchito

Kuzizira kumafa chitsulo, kuuma kwachitsulo, kuzimitsa, ndi kuuma mtima, kuvala kukana, mphamvu ndipamwamba kuposa Cr12. Amagwiritsidwa ntchito popanga mitundu yosiyanasiyana ya zida zoziziritsa kuzizira komanso zida zokhala ndi magawo akulu akulu, mawonekedwe ovuta komanso zolemetsa zogwirira ntchito, monga nkhonya kufa, kudula kufa, payipi kufa, kujambula mozama kumafa, macheka ozungulira, zida zokhazikika, ndi geji , ndi zina.
