⑥Kunconywa ukusebenzisa ubulukhuni be-62 ~ 64HRC kwi-convex kunye ne-concave molds esetyenziselwa ukwenza i-copper extrusion molds ebandayo.
⑦I-convex kunye ne-concave molds esetyenziselwa i-molds yentsimbi ebandayo ye-extrusion iyacetyiswa ukuba ibe nobunzima be-62 ~ 64HRC.
⑧Iiplati zetsimbi zasentwasahlobo kunye neqhekeza elikhulu le-0.65% ~ 0.80% esetyenziselwa ukwenza i-carbon inobunzima be-37 ~ 42HRC, inikezela ubomi obufikelela kwi-150000 imijikelezo.
⑨Iipleyiti zensimbi zasentwasahlobo ezinobunzima be-0.65% ukuya kwi-0.80% esetyenziselwa ukwenza i-carbon enobunzima be-37-42HRC, kunye nonyango olongezelelweyo lwe-nitriding, ubomi babo benkonzo bunokufikelela kumaxesha angama-400000.
Ⅲ-Iyaqhuba of Cr12MoV Cold Working Die Steel:
Ukucaciswa kokuthambisa isikhunta esibandayo se-extrusion: Khusela kwaye ushushu umngundo ngeefayili zentsimbi kwiqondo lobushushu le-760-780℃kwiiyure ze-10, ngokupholisa isithando somlilo kunye nobunzima be-196HBW.Ukubunjwa kwe-extrusion ebandayo kunokufezekiswa kakuhle.
Ukucaciswa kwe-isothermal spheroidizing annealing eqhelekileyo: 850-870℃ ×Iiyure ezingama-3-4, zipholile kwisithando somlilo ukuya kwi-740-760℃ ×Iiyure ezi-4-5 zonyango lwe-isothermal, kunye nobunzima bokupholisa umoya≤I-241HBW, ibakala le-eutectic carbide≤3, ubushushu be-isothermal obufanelekileyo 740-76o℃, kunye nexesha≥4-5 iiyure.
Ukucaciswa kwe-spheroidizing annealing: (860± 10)℃ ×Iiyure ezingama-2-4, ukupholisa isithando somlilo ngesantya sokupholisa se-30℃ngeyure, (740± 10)° C x 4-6 iiyure, ukupholisa kancinci ukuya kwi-500-600℃ngesithando somlilo, ukupholisa umoya emva kokuphuma, ubunzima 207-255HBW.
Ukucima ngokubanzi kunye neenkcukacha zokufudumala: ukucima ukushisa kwe-1000-1050℃, ukucima ioli okanye ukucima, ubunzima be-260HRC, ukushisa kweqondo lokushisa kwe-160-180, ixesha lokunciphisa iiyure ze-2, okanye ukushisa kwe-325-375° C, ukuthambisa 2-3 amaxesha.
Ukucima okuphantsi kunye nobushushu obuphantsi bokucima ukucima: 950℃-1040℃, ubushushu bobushushu bumalunga nama-200℃, ukucaphuka okwesibini.
Ukucima okuphezulu kunye nobushushu obuphezulu bokucima: 1050-1100℃, ubushushu bobushushu bumalunga nama-520℃, ukucaphuka okwesibini.Indlela yesibini yokuqina esetyenziselwa ukucima okuphezulu kunye nokuhlaziywa okuphezulu kuphucula ubulukhuni, kodwa iinkozo ziya kukhula.
Unyango lwe-Cryogenic: Intsimbi ye-Cr12MoV ifumana unyango lwe-cryogenic, olunokuthi luqhubekisele phambili i-ultrafine carbides ehlakazekileyo ukusuka kwi-martensite ecinyiweyo, kwaye ke ezi carbides ze-ultrafine zingatshintshwa zibe yi-carbides emva kwe-200.℃ubushushu obuphantsi.I-martensite ngaphandle konyango lwe-cryogenic ibeka kuphela inani elincinci le-carbide kwezinye iindawo zendawo emva kokushisa okuphantsi komlilo ojikelezayo.
I-Jinbaicheng ithatha indlela yonyango yokushisa kweekhemikhali ephantsi yokushisa, egcina ubunzima obuphezulu kunye nokumelana nokunxiba kwentsimbi ye-Cr12MoV.Izaleko ezintathu eziqhele ukusetyenziswa kwikhemikhali ephantsi yobushushu obuphantsi, ezizezi, iion nitriding, igesi nitrocarburizing, kunye nebhafu yetyuwa yesalfure cyanide co nitriding, zinempembelelo enkulu yokuxhathisa kunye nokuncamathela, kunye nebhafu yetyuwa yesalfure cyanide co nitriding yeyona ilungileyo.
Ubomi benkonzo yomzobo bufa kuJinbaicheng's I-Cr12MoV izixhobo zensimbi ezingenasici, emva kokunyangwa kwegesi ye-nitrocarburization, ifikelela ngaphezu kweengcezu ze-30000, ezinde ngaphezu kwamaxesha e-10 ngaphezu kwe-molds efanayo ephathwa ngokucinywa okuqhelekileyo kunye nokufudumala.
