I-Cr12MoV insimbi eshisayo egoqiwe imigoqo eyindilinga

Insimbi ye-Cr12MoV inokuqina okuphezulu, futhi lezo ezinesiphambano esingu-300 kuya ku-400 mm noma ngaphansi zingacinywa ngokuphelele.
Ingakwazi ukugcina ubulukhuni obuhle nokumelana nokugqoka ku-300 ～ 400℃, ukuqina kwayo kuphakeme kunensimbi ye-Cr12, futhi ukuguqulwa kwayo kwevolumu kuncane ngesikhathi sokucisha. Ingasetshenziselwa ukwakha isikhunta namathuluzi ahlukahlukene anezigaba ezinkulu eziphambanayo, izimo eziyinkimbinkimbi, futhi imelane nemithwalo emikhulu yomthelela. Isibonelo, ukubhoboza kufa okunezimo eziyinkimbinkimbi, okufakwayo kumafa ayinkimbinkimbi, umdwebo ojulile wensimbi uyafa, umdwebo wezintambo uyafa, ipuleti lentambo elinentambo, i-cold extrusion iyafa, izikele zokusika ezibandayo, amasaha ayindilinga, amathuluzi ajwayelekile, amathuluzi okulinganisa, njll.
Insimbi ye-Cr12MoV iyinsimbi enekhabhoni ephezulu, ene-molybdenum lysic. Okuqukethwe kwekhabhoni yayo kuphansi kakhulu kunaleyo yensimbi ye-Crl2, futhi yengezwa ngezinto ze-molybdenum ne-vanadium, ezithuthukisa kakhulu izici zokucubungula ezishisayo zensimbi, ukuqina komthelela kanye nokusatshalaliswa kwe-carbide . Insimbi inokumelana nokugqoka okuphezulu, ukuqina, ukuqina, ukuqina, ukuzinza okushisayo, amandla okucindezela, kanye nokuguqulwa kwe-micro, ukusebenza okuhle kakhulu okuphelele nokuguquguquka okubanzi. Izinga lokushisa elithambisa ukushisa lingu-520 ℃. Usayizi wokusika ungaphansi kuka-4mm futhi ungaqiniswa ngokuphelele. Ukumelana nokugqoka kwalesi nsimbi kuphindwe izikhathi ezingu-3 ~ 4 kunensimbi yamathuluzi aphansi, futhi ivolumu yokucisha incane. Ukujula kokuqina: ukucisha uwoyela 200 ~ 300mm.
Phakathi nenqubo ye-crystallization, inani elikhulu lama-eutectic white carbides akhiwa (ingxenye ye-carbonized substance cishe i-20%, futhi izinga lokushisa le-eutectic lingaba ngu-1150 ° C). Lawa ma-carbides aqinile kakhulu futhi aqinile. Nakuba ama-carbide ephukile ngezinga elithile ngemva kokugingqika kwe-billet, ama-carbides asakazwa ngamabhande, ama-slabs, amabhlogo, nezinqwaba eduze nokuqondisa okugoqayo, futhi izinga lokuhlukaniswa liyakhula ngobubanzi bensimbi.
