Kodi kutentha kwa kutentha kwa a286 ndi kiyi?

Njira yotentha ya kutentha kwa A286 Yoyimitsa Yopindika Kwambiri Makamaka magawo awiri: Njira Yothandizira ndi Kukalamba. Njira yodziwika bwino ndi masitepe ali motere:

1. Chithandizo cha yankho
– Kutentha: Mwachinthu, kutentha pa 982 ° C (1800°F) kwa ola limodzi, kutsatiridwa ndi kuzizira kofulumira. Miyezo ina imalimbikitsa kugwira pa 899 ° C kwa maola awiri, kutsatiridwa ndi kuzizira kofulumira.
– Njira Yozizirira: Mwachinthu, Kuziziritsa mpweya kapena kuzimitsa mafuta kumagwiritsidwa ntchito.
– Cholinga: Kutentha kwakukulu kumasungunula ma carbides ndi nitrides mu alloy, zomwe zimapangitsa kuti pakhale gawo limodzi la austenite, kuchepetsa kupsinjika kwa processing, ndi kukonza kulimba ndi ductility wa zinthu.

2. Chithandizo cha Ukalamba
– Kutentha: 704-760°C (1300-1400°F).
– Kusunga Nthawi: Mwachinthu 12-16 maola, kutsatiridwa ndi kuziziritsa kwa mpweya.

3. Chithandizo Chapadera
– Kukalamba Pawiri: Nthawi zina, mankhwala okalamba awiri amachitidwa. Izi zimaphatikizapo kugwira pa 704/760 ° C kwa 16 maola, kenako mpweya wozizira mpaka 649 ° C, kugwirizira wina 8-12 maola, ndipo potsiriza kuziziritsa mpweya. Chithandizochi chimawonjezeranso mphamvu yakusweka kwa notch ndikusunga bwino pakati pa kulimba ndi kuuma.
– Kusintha kwa Dimensional: Pambuyo pa kukalamba, zakuthupi zidzachepa pang'ono, pafupifupi 0.001 mu/mu.

4. Kusamalitsa
– Kuwongolera Kutentha: Kutentha kwa yankho ndi ukalamba mankhwala ayenera mosamalitsa ankalamulira kuonetsetsa mulingo woyenera kwambiri zakuthupi katundu.
– Mtengo Wozizira: Mlingo wozizira pambuyo pa chithandizo chamankhwala umakhudza kwambiri zinthu zakuthupi. Kuzizira kofulumira kumathandizira kukwaniritsa kapangidwe kabwino kambewu, potero kumawonjezera kulimba.
– Kukalamba Kobwerezabwereza: Nthawi zina, mankhwala okalamba angapo angafunike kuti apititse patsogolo zinthu zakuthupi.

Kupyolera mu ndondomeko kutentha kutentha, choyikapo chotsekera cha A286 chimakhala ndi mphamvu zotentha kwambiri, kukana dzimbiri, ndi katundu wabwino processing, kukwaniritsa zofunikira pakugwiritsa ntchito madera ovuta kwambiri monga zamlengalenga.
