zofunika
D3 Tool Steel ndi chitsulo cha carbon high-chromium, high-chromium, choumitsa mafuta chomwe chimadziwika ndi kuuma kwakukulu komwe kungatheke komanso ma carbides ambiri, akuluakulu, okhala ndi chromium mu microstructure. Ma carbides awa amapereka kukana kwabwino kuvala kuchokera pakulumikizana ndi zitsulo zina ndi zinthu zonyezimira.

D3 imawonetsa kukhazikika kwabwino pakuchiritsa kutentha, kugwira kukula pafupifupi komanso kuuma mpweya, kaboni wambiri, zitsulo zamtundu wa chromium monga D2.

KUCHITAPO: Kupanga mipukutu, kujambula kumafa, kupanga, zida zophatikizira ufa, ndi kupukuta kumafa.

MAVUTO

Kutentha Kwambiri:

Ac1: 1440 ° F (782 ℃))

Ac3: 1530 ° F (8320 ℃))

AR1: 1410 ° F (766 ℃))

AR3: 1370 ° F (743 ℃))

Kutentha: Kuchepetsa kupotoza ndi kupsinjika mu zida zazikulu kapena zovuta gwiritsani ntchito preheat iwiri. Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1200-1250 ° F (649-677 ° C) mofanana, ndiye kutentha kwa 1400-1450 ° F (760-788 ° C). Pazida zabwinobwino, gwiritsani ntchito kutentha koyambirira kokha ngati njira imodzi yopangira kutentha.

Kutentha Kwambiri (Kutentha Kwambiri): Kutenthetsa pang'onopang'ono kuchokera ku preheat kufika 1700-1750 ° F (927-954 ° C)

Kuzimitsa: Pa mafuta, zimitsani mpaka wakuda, pafupifupi 900 ° F (482 ° C), kenako kuziziritsa mu mpweya wokhazikika mpaka 150-125 ° F (66-51 ° C).

Kwa gasi wopanikizika, ng'anjoyo iyenera kukhala ndi mphamvu yocheperapo ya 4 mipiringidzo. Kuzimitsa kwa pafupifupi 400 ° F (222 ° C) pamphindi kufika pansi pa 1000 ° F (538 ° C) ndikofunikira kuti mupeze zinthu zomwe mukufuna.

Kutentha: Kupsa mtima mwamsanga pambuyo kuzimitsa. Gwirani kutentha kwa ola limodzi pa inchi (1 mm) ya makulidwe, osachepera maola awiri, kenako mpweya wozizira mpaka kutentha kozungulira.

Kuti muzitha kuvala kwambiri, kupsa mtima pakati pa 300-350 ° F (149-177 ° C) pa kuuma kwa 62-63 HRC. Kuti mukhale ndi malire abwino pakati pa kukana kuvala ndi kulimba, kupsa mtima pakati pa 450-500 ° F (232-260 ° C). Izi zidzatulutsa 58-60 HRC.

Kuchepetsa kupsinjika kwamkati m'magawo akuluakulu kuposa mainchesi 6 (152.4 mm) ndikuwongolera kukhazikika kwa zida zomwe zidzakhale EDM'd pambuyo pa chithandizo cha kutentha, nthawi zothira maola 4 mpaka 6 pa kutentha kotentha zimalimbikitsidwa kwambiri.

ZINTHU ZOFUNIKA

Annealing iyenera kuchitidwa mutatha kugwira ntchito yotentha komanso musanalimbikitsenso.

Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1600-1650 ° F (871-899 ° C), ndipo sungani kutentha kwa ola limodzi pa inchi (1mm) ya makulidwe apamwamba; 25.4 maola osachepera. Ndiye kuziziritsa pang'onopang'ono ndi ng'anjo pa mlingo wosapitirira 2 ° F pa ola (50 ° C pa ola) mpaka 28 ° F (1000 ° C). Pitirizani kuziziritsa kutentha kozungulira mu ng'anjo kapena mpweya. Zotsatira zake kuuma kuyenera kukhala kopitilira 538 HBW.

Chithandizo cha Cryogenic: Chithandizo cha firiji chiyenera kuchitidwa pambuyo pa kupsa mtima koyamba, ndipo kuyenera kutsatiridwa ndi kupsya mtima kachiwiri.
