zofunika

Chitsulo cha H13 ndiye chida choyimira kwambiri chomwe chimagwiritsidwa ntchito kwambiri. Monga nkhungu za extrusion ndi zitsulo zoponyera zitsulo. Imatchedwanso DIN 1.2344 ndi JIS SKD61 chitsulo. H13 zitsulo zozungulira mbale mbale kutentha mankhwala zofunika kwambiri.The chachikulu annealing processing angatsogolere ntchito zitsulo.

Mapulogalamu:

Chitsulo cha 1.2344 chimakhala ndi makina abwino ndipo chimagwiritsidwa ntchito kwambiri pamakampani, monga kupanga extrusion kufa, kulipira kufa ndi katundu wambiri, kulipira molondola kufa ndi zina zotero. Mwa njira, pamwamba pa nkhungu kumadutsa nitriding kapena cyanidation, moyo wothandizira wa nkhungu ukuwonjezeka.


MALANGIZO OTHANDIZA KUTENTHA KUTI: KUVUTA

Kutentha Kwambiri:
Ac1: 1544 ° F (840 ℃))Ac3: 1634 ° F (890 ℃))
AR1: 1475 ° F (802 ℃))AR3: 1418 ° F (826 ℃))

Annealing

Kutenthetsa pang'onopang'ono mpaka 1550 ° -1650 ° F, gwirani mpaka misa yonse itatenthedwa, ndipo muziziziritsa pang'onopang'ono mu ng'anjo (40F pa ola) kuti pafupifupi 1000°F, 

pambuyo pake kuzirala kungawonjezeke. Kusamala koyenera kuyenera kutengedwa kuti mupewe kuchuluka kwa carburization kapena decarburization.

Kupanikizika Kupumula

Ngati mukufuna kuthetsa mavuto a makina, tenthetsani pang'onopang'ono mpaka 1050 ° -1250 ° F, lolani kuti mufanane, kenako muziziziritsa mumpweya wokhazikika (Strain Relieving).


Preheat Isanafike kuumitsa

Kutentha pang'ono musanalowetse mu ng'anjo yamoto, yomwe iyenera kugwira ntchito pa 1400 ° -1500 ° F.


Kuthetsa: Mpweya, gasi woponderezedwa, kapena mafuta ofunda. Makulidwe a gawo mpaka ndi kuphatikiza mainchesi 5 (127 mm) 

adzaumitsa kwathunthu pamene utakhazikika mu mpweya wokhazikika kuchokera ku mankhwala austenitizing. 

Magawo okulirapo kuposa mainchesi 5 (127 mm) adzafunika kuziziritsa mwachangu pogwiritsa ntchito mpweya wokakamiza, 

gasi woponderezedwa, kapena kuzimitsa mafuta kosokoneza kuti mupeze kuuma kwakukulu, kulimba komanso kukana 

matenthedwe kutopa akulimbana.

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).
