O1 chida chitsulo ndi otsika aloyi ozizira ntchito chida chitsulo chimene chiyenera kuzimitsidwa mafuta pa kutentha kutentha. Chitsulo cha chida cha O1 chili ndi manganese pang'ono, tungsten, ndi chromium, zomwe zimapatsa chida cha O1 kulimba kokwanira pazida wamba & ntchito zakufa. Chitsulo cha O1 chili ndi zinthu zowumitsa kwambiri zokhala ndi tirigu wabwino kwambiri wokhala ndi kulimba kwachilendo. Chitsulo cha O1 chimakhala ndi kuyankha kwabwino pakuchiza kutentha ndi kusintha kwakung'ono. Kukula kopitilira pafupifupi mainchesi 2 kukhuthala kapena kuzungulira kumatha kuwonetsa kulimba kocheperako mkati. Chitsulo cha chida cha O1 chimapezeka mumayendedwe aulere a de-carb, ma flats ndi mabwalo, komanso kusankha kwakukulu kwambiri pamitengo yapansi panthaka ndi ndodo yobowola pazida zonse zachitsulo.


Mapulogalamu:

Ngati kukhazikika kwamphamvu kwambiri pakuchiritsa kutentha kapena kukana kuvala bwino kumafunika, zitsulo zokhala ndi aloyi wapamwamba kwambiri, monga A2 kapena D2 ziyenera kuganiziridwa.

Kupanga kwa ASTM O1 Tool Steel

Kutenthetsa kwa kupanga chitsulo chamafuta O1 kuyenera kuchitika pang'onopang'ono komanso mofanana. Kupanga zitsulo za alloy O1 kumatha kuchitidwa pa 980-1000 ° C, ndikutenthetsanso nthawi zonse ngati kuli kofunikira. Koma osapanga pansi pa 800 ° C. Pambuyo popanga chitsulo cha AISI O1, kuziziritsa pang'onopang'ono mu laimu, mica, phulusa louma kapena ng'anjo. Zida za ASTM O-1 ziyenera kutsekedwa nthawi zonse pambuyo popanga.


AISI O1 Chida Chothandizira Kutentha kwachitsulo


 Nkhani

Annealing iyenera kuchitidwa mutatha kugwira ntchito yotentha komanso musanalimbikitsenso.

Kutenthetsa pamlingo wosapitirira 222 ° C pa ola mpaka 802-816 ° C, ndipo gwirani 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°C pa ola kufika 28°C. Pitirizani kuziziritsa kutentha kozungulira mu ng'anjo kapena mpweya. Zotsatira zake kuuma kuyenera kukhala kopitilira 538 HBW.


 Kuchepetsa Kupsinjika kwa Zinthu Zosalimba

Kutenthetsa pang'onopang'ono mpaka 1250 ° F. Zilowerereni kwa maola awiri pa inchi ya makulidwe pa kutentha. Kuzizira kozizira (ng'anjo yoziziritsa ngati n'kotheka) mpaka kutentha.


Kuumitsa

1.Preheat: Kutenthetsa pang'ono musanayipire mu ng'anjo ya preheat, yomwe iyenera kugwira ntchito pafupifupi 1100 ° -1200 ° F.

2.Kuumitsa: Kutenthetsa mpaka 1475 mpaka 1500 ° F. Zilowerereni pa kutentha kwa mphindi 30 pa inchi ya makulidwe.

3.Zimitsani: Zimitseni chitsulo cha O1 mu mafuta ofunda ndikulola kuti muzizizira mu mafuta mpaka kutentha kwa 125 ° -150 ° F kwafika, kapena kumene gawolo lingakhoze kuchitidwa m'manja opanda kanthu, ndi kupsa mtima mwamsanga.

4.Kutentha: Nthawi zambiri zitsulo zowumitsa mafuta zimafunikira kukhala okwiya okha. Komabe, kupsa mtima pawiri nthawi zina kumakhala kokonda. Zilowerereni pa kutentha kwa maola 2 pa inchi ya makulidwe pa kupsya mtima kulikonse. Mpweya wozizira mpaka kutentha kwapakati. Kutentha kwabwino kwa kalasi iyi ndi 300 mpaka 450 ° F.


 Kuchepetsa Kupsinjika Maganizo

Kuchepetsa kupsinjika kwa zinthu zolimba kumalimbikitsidwa kwambiri pambuyo pogaya kwambiri, kapena kuwotcherera, kapena EDM. Sankhani kutentha komwe ndi 25 kapena 50 ° F kutsika kuposa kutentha komaliza komwe kunagwiritsidwa ntchito.
