zofunika

H13 Tool Steel ndi chitsulo chosasunthika cha chromium-molybdenum chomwe chimagwiritsidwa ntchito kwambiri pantchito yotentha ndi zida zozizira. Kuuma kotentha (kutentha kwamphamvu) kwa H13 kumalimbana ndi kutopa kwamafuta komwe kumachitika chifukwa cha kutenthetsa kwapang'onopang'ono ndi kuziziritsa m'zinthu zotentha zogwiritsa ntchito zida. Chifukwa cha kuphatikiza kwake kwakukulu kolimba kwambiri komanso kukana kutopa kwamafuta (komwe kumadziwikanso kuti kuyang'ana kutentha) H13 imagwiritsidwa ntchito pazida zotentha kwambiri kuposa zida zina zilizonse.

Chifukwa cha kulimba kwake kwakukulu komanso kukhazikika kwabwino kwambiri pakuchiza kutentha, H13 imagwiritsidwanso ntchito pazida zosiyanasiyana zozizira. M'magwiritsidwe awa, H13 imapereka kulimba kwabwinoko (kupyolera mu kuuma kwa magawo akulu) komanso kukana kuvala bwino kuposa zitsulo wamba wa alloy monga 4140.

Imapezekanso ngati zinthu za Electro-Slag-Remelted (ESR) ndi Vacuum-Arc-Remelted (VAR) komanso. Njira zotsitsimutsa zimapereka kusinthika kwamankhwala, kuwongolera kukula kwa carbide, ndikusintha komwe kumayenderana ndi makina komanso kutopa.

KUCHITAPO:Kuyika, zokutira, ndi zotsekemera zimafera kufa, kufa kumanja kuponyera mfuti, kufa kumoto kotentha, kufa kwa extrusion, ndi zotsekemera za pulasitiki ndi zinthu zina zomwe zimafuna kulimba kwambiri komanso kupindika kwambiri.

MAVUTO

Kutentha Kwambiri:

Ac1: 1544 ° F (840 ℃))

Ac3: 1634 ° F (890 ℃))

AR1: 1475 ° F (802 ℃))

AR3: 1418 ° F (826 ℃))

Kutentha: Kuti muchepetse kupotoza mu zida zovuta gwiritsani ntchito preheat iwiri. Kutentha pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1150-1250 ° F (621-677 ° C), kufananiza, kenako kwezani ku 1500-1600 ° F (816-871 ° C) ndi kufanana. Pazida zodziwika bwino, gwiritsani ntchito kutentha kwachiwiri kokha ngati chithandizo chotenthetsera chimodzi.

Kutentha (Kutentha Kwambiri): Kutenthetsa msanga kuchokera ku preheat. Ng'anjo kapena Mchere: 1800-1890 ° F (982-1032 ° C) Kuti mukhale wolimba kwambiri, gwiritsani ntchito 1800 ° F (982 ° C) Kuti mukhale olimba kwambiri komanso kuti musagwirizane ndi kutopa kwa kutentha ndi kuvala ntchito 1890 (1032 ° C). Zilowerereni pa kutentha kwa mphindi 30 mpaka 90.

Kuthetsa: Mpweya, gasi woponderezedwa, kapena mafuta ofunda. Kukhuthala kwa magawo mpaka mainchesi 5 (127 mm) nthawi zambiri kumakhala kolimba pamene kuziziritsidwa mumpweya wosasunthika kuchokera kumankhwala olimbikitsa. Magawo okulirapo kuposa mainchesi 5 (127 mm) adzafunika kuziziritsa mwachangu pogwiritsa ntchito mpweya wokakamiza, gasi woponderezedwa, kapena kuzimitsa mafuta kodukizadukiza kuti mupeze kulimba, kulimba komanso kukana kutopa kwamafuta.

Kuti gasi azimitsidwa mopanikizika, kuzimitsa pang'ono kwa pafupifupi 50 ° F pamphindi (28 ° C pamphindi) mpaka pansi pa 1000 ° F (538 ° C) kumafunika kuti mupeze zinthu zabwino kwambiri muzitsulo.

Kwa mafuta, kuzimitsa mpaka wakuda, pafupifupi 900 ° F (482 ° C), kenako kuziziritsa mumlengalenga mpaka 150-125 ° F (66-51 ° C).

Kutentha: Mtima mwamsanga pambuyo pa kuzimitsa. Mtundu woyatsa kwambiri ndi 1000-1150 ° F (538-621 ° C). Gwiritsani kutentha kwa ola limodzi pa inchi (1mm) makulidwe, koma kwa maola awiri osachepera, kenako mpweya wabwino kuzizira kozungulira. Kutentha kawiri kumafunika. Kuti tiwonjezere kulimba ndi magwiridwe antchito, kupsa mtima kwachitatu kumagwiritsidwa ntchito ngati kupumula kwa nkhawa mukamaliza kumaliza kukonza, kupera, ndi ntchito ya EDM kumalizika pachidacho.

ZINTHU ZOFUNIKA

Annealing iyenera kuchitidwa mutatha kugwira ntchito yotentha komanso musanalimbikitsenso.

Kutentha pamlingo wosapitirira 400 ° F pa ola limodzi (222 ° C pa ola limodzi) mpaka 1575-1625 ° F (857-885 ° C), ndikugwiritsanso kutentha kwa ola limodzi pa inchi yakulimba kwambiri; Maola awiri osachepera. Kenako muzizizira pang'onopang'ono ndi ng'anjo pamlingo wosapitirira 1 ° F pa ola limodzi (2 ° C pa ola limodzi) mpaka 50 ° F (28 ° C). Pitirizani kuzizira kutentha kozungulira m'ng'anjo kapena mumlengalenga. Chowuma chotsatira chimayenera kukhala chambiri cha 1000 HBS.
