    Kutentha kwa kulipira wa AISI D2 chida zitsulo ayenera
    kuchitidwa pang'onopang'ono uniformly. Zilowerere kudzera pa 1850 ° -1950 ° F ndi Tenthetsaninso nthawi
    ngati kuli kofunika, kuima ntchito pamene kutentha akutsikira m'munsimu 1700 ° F (926 ℃). Pambuyo D2
    kufa zitsulo kulipira, kuziziritsa pang'onopang'ono mu laimu, Mica, phulusa youma kapena ng'anjo. AISI D2 zitsulo
    nthawi zonse annealed pambuyo kulipira.

    5. D2 Chida Zitsulo Kutentha Chithandizo

    • kutentha Chithandizo

    ASTM D2 steels aloyi ayenera preheated pang'onopang'ono kuti 815oC (1500oF) kenako kutentha akhoza ziwonjezeke kwa 1010oC (1850oF). Iwo ndiye unachitikira ku 1010oC (1850oF) kwa mphindi 20 mpaka 45 ndi mpweya utakhazikika (mpweya kuzimitsidwa).

    • Annealing

    Annealing wa D2 chida steels zinthu zichitike pa 871 kuti 898oC (1600 kuti 1650oF) akutsatiridwa ndi ng'anjo pang'onopang'ono yozizira pa 4.4oC (40oF) pa ola limodzi kapena less.after zomwe yozizira mlingo akhoza ziwonjezeke. kusamalitsa abwino ayenera kumwedwa kuletsa carburization kwambiri kapena decarburization.

    • kupanikizika Kuchepetsa

    Pamene zofunika kuti tichepetse tizilombo ta Machining, kutentha D2 kalasi zitsulo pang'onopang'ono 1050 ° -1250 ° F, kulola mwakufuna, ndiyeno kuziziritsa mu akadali mpweya (Unasi wotsitsimutsa).

    • Preheat Isanafike nakawumitsa

    Preheat pang'onopang'ono 1350 ° -1450 ° F ndi kugwira kutentha mpaka kalasi zitsulo D2 zakuthupi uniformly mkangano.

    • kuumitsa

    Pambuyo preheating mokwanira, kutentha kwa 1800 ° -1850 ° F. Gwirani chidutswa ntchito pa kutentha oipa mpaka kwathunthu ndi uniformly mkangano.

    • Kuthetsa

    AISI D2 zitsulo chida zakuthupi ndi mpweya oipa zitsulo ndi kukhazikitsa kuuma pa yozizira mu akadali mpweya. Kupewa makulitsidwe ndi kuteteza decarburization a pamwamba ntchito chidutswa, olamulidwa mpweya kapena zingalowe ng'anjo analimbikitsa. Ngati ng'anjo izi palibe, kumunyamula kuumitsa, osambira mchere kapena kuzimata chidutswa mu zojambulazo zosapanga dzimbiri idzapereka digiri ya chitetezo pamwamba mu ndondomeko oipa. Mbali ayenera kuloledwa kuti kuziziritsa kwa 150F, kapena kumene iwo angakhoze unachitika mu dzanja umboni, kenako chiphwanye yomweyo.

    • Tempering

    The tempering kutentha pa zinthu D2 zitsulo akhoza zosiyanasiyana malinga ndi kuuma ankafuna. steels D2 akhoza kulola pa 204oC (400oF) kwa kukwaniritsa Rockwell C kuuma 61 ndi pa 537oC (1000oF) kwa Rockwell C kuuma 54.

    6. D2 Chida Zitsulo Zofunika Phunziro pankhaniyi
     AISI kalasi D2 chida steels ntchito pamapeto pake tooling ntchito, kumene kuvala kulimbana ndi zofunika, monga blanking kapena kupanga mpweya ndi ulusi anagubuduza afa.

    Ena ntchito chachikulu D2 chida zitsulo ndi monga pansipa:

    Blanking Amwalira, Ndimapanga Amwalira, Coining Amwalira, Slitting osema miyala, Likupita Zida, Long nkhonya, Ndimapanga Rolls, Edging Rolls, Master Zida, Beading Rolls, zosamvetsetseka nkhonya, Extrusion Amwalira, Chojambula Amwalira, Lamination Amwalira, ulusi anagubuduza Amwalira, asenge masamba, Burnishing zida, Gauges, Knurls, Bvalani Mbali.

    Ife zambiri kugwira D2 chida zitsulo ntchito zogulitsa, ndipo mungafune mtengo wathu pa ndandanda. Lumikizanani nafe ndipo lowani mu nyuzipepala lathu D2 chida zitsulo zipangizo mtengo mndandanda ndipo amagwira malonda lero.
