Kukho iindlela ezilishumi ezisetyenziswa ngokuqhelekileyo zokucima kwiinkqubo zokunyanga ubushushu, ezizezi, i-single medium (amanzi, ioli, umoya) ukucima; Ukucima okuphakathi kabini; Ukucima i-martensite ngokwamanqanaba; Ukucinywa ngokwemigangatho kwe-martensite ngaphantsi kwe-Ms point; Indlela yokucima isothermal ye-Bainite; Indlela yokucima i-Composite; Indlela yokucima i-isothermal yangaphambi kokupholisa; Ukulibaziseka kwendlela yokucima ukupholisa; Indlela yokunciphisa kunye nokunciphisa umzimba; Indlela yokutshiza yokucima, njl.

1、 Indlela enye (amanzi, ioli, umoya) yokucima

Indlela enye (amanzi, i-oyile, umoya) yokucima: Ukucima ii-workpieces ezithe zafudunyezwa ukucima ubushushu kwindawo yokucima ukuze zizipholise ngokupheleleyo. Le yeyona ndlela ilula yokucima, esetyenziswa ngokuqhelekileyo kwi-carbon steel kunye ne-alloy workpieces yensimbi enemilo elula. Ukucima ukucima kuya kukhethwa ngokwe-coefficient yokudlulisa ukushisa, ukuqina, ubungakanani, imilo, njl.

3、 Inyathelo lokucinywa kwe-martensite Inyathelo lokucima i-martensite: intsimbi i-austenitized, kwaye emva koko intywiliselwe kwindawo engamanzi (ibhafu yetyuwa okanye i-alkali yokuhlamba) kunye nobushushu obuphezulu kancinane okanye obungaphantsi kunomgangatho ophezulu we-martensite wentsimbi, kwaye igcinwe ixesha elifanelekileyo. . Xa iileyile zangaphakathi nangaphandle zentsimbi zifikelela kwiqondo lokushisa eliphakathi, zithathwa ukuze zipholile umoya, kwaye i-austenite epholileyo iguqulwa ngokukhawuleza ibe yi-martensite. Ngokuqhelekileyo isetyenziselwa izixhobo zokusebenza ezincinci ezineemilo ezintsonkothileyo kunye neemfuno ezingqongqo zokuguqulwa, le ndlela ikwasetyenziswa ngokuqhelekileyo ukucima isinyithi esinesantya esiphezulu kunye ne-alloy high metal molds. 4、 Ukucinywa kwamanqanaba e-martensite ngezantsi kweNkskz inqanaba lokucinywa kwe-martensite ngezantsi kweNksk. zifunyenwe xa ubukhulu bukhulu. Ngokuqhelekileyo isetyenziselwa izinto zokusebenza zentsimbi ezinobungakanani obuphantsi. 5、 Indlela yokucima i-Bainite isothermal yokucima i-isothermal: cima i-workpiece kwindawo yokuhlambela kwiqondo lobushushu elisezantsi le-bainite yentsimbi ukuya kwi-isothermal, ukuze ikwazi ukwenza utshintsho olusezantsi lwe-bainite, kwaye ngokubanzi uyigcine ebhafini kangange-30~60min. Inkqubo yokucima isothermal bainite inamanyathelo amathathu angundoqo: ① austenitizing; ② Ukupholisa unyango emva kwe-austenitization; ③ Unyango lwe-isothermal ye-Bainite; Ngokuqhelekileyo isetyenziswa kwintsimbi ye-alloy, intsimbi ephezulu yekhabhoni yentsimbi encinci, kunye ne-ductile iron castings. 6、 Indlela yokucima i-Composite

Indlela yokucima umdibaniso: i-workpiece icinywa ukuya ngaphantsi kukaNks ukufumana i-martensite kunye neqhezu lomthamo we-10% ~ 30%, kwaye emva koko i-isothermal kwindawo ephantsi ye-bainite ukufumana izakhiwo ze-martensite kunye ne-bainite yezinto zokusebenza ezinamacandelo amakhulu anqamlezayo, adla ngokusetyenziswa ingxubevange izixhobo zentsimbi. 7、 Indlela yokucima i-Isothermal yokuCima kwangaphambili Ukupholisa i-Isothermal Indlela yokuCima: Ekwaziwa ngokuba yiTemperature Rise Isothermal Quenching, iinxalenye ziqala zipholiswe kwiqondo lobushushu elisezantsi (elikhulu kunoMs) lokuhlambela, kwaye emva koko idluliselwe kwibhafu yobushushu ephezulu ukuze ingene kwinguqu ye-isothermal ye-austenite. Ifanele iinxalenye zentsimbi ezinobunzima obuphantsi okanye izixhobo zokusebenza ezinemilinganiselo emikhulu efuna ukucinywa kwe-isothermal.

8、 Indlela yokucima ukupholisa ilibazisekile

Indlela yokucima ukupholisa okulibazisekileyo: Amalungu aqala apholiswa kwiqondo lobushushu elingaphezulu kancinane kune-Ar3 okanye i-Ar1 emoyeni, emanzini ashushu, okanye kwibhafu yetyuwa, emva koko aphantsi kokucinywa okuphakathi okukodwa. Isetyenziswa ngokuqhelekileyo kumalungu aneemilo ezintsonkothileyo, ubukhulu obuguquguqukayo kwiindawo ezahlukeneyo, kwaye ifuna i-deformation encinci.

9, Indlela yokuzicima: Fudumeza zonke izixhobo zokusebenza ezisetyenzisiweyo, kodwa ngexesha lokucima, ngamalungu kuphela afuna ukuqina (ngokuqhelekileyo iindawo ezisebenzayo) antywiliselwa kwisisombululo sokupholisa. Linda de ezo ndawo zingantywiliselwanga zinyamalale, kwaye ngoko nangoko uzisuse ukuze zizipholise emoyeni. Indlela yokucima kunye nokuzifudumeza isebenzisa ubushushu obungapholiswanga ngokupheleleyo ngombindi ukuze budluliselwe kumphezulu, obangela ukuba umphezulu ube nomoya. Izixhobo eziqhele ukusetyenziswa ukumelana neempembelelo, ezifana neetshizili, iipunch, iihamile, njl. njl.、 Indlela yokucima isitshizi: Indlela yokucima apho amanzi afafazwe kwindawo yokusebenza, kwaye ukuhamba kwamanzi kunokuba kukhulu okanye kuncinci, kuxhomekeke kubunzulu obufunekayo bokucima. Indlela yokucima isitshizi ayifaki ifilimu yomphunga phezu kwendawo yokusebenza, eqinisekisa ukuba umgangatho onzulu wokuqina ufunyenwe kunokuba ucime emanzini e-Xitong. Isetyenziswa ikakhulu ukucima umphezulu wendawo.
