Mkhalidwe wotumizira

Kuzimitsa: pambuyo Kutentha kwa gawo kusintha mfundo kutentha pamwamba, lakuthwa kuzirala ndondomeko.Wonjezerani kuuma kwa zinthu, koma kuchepetsa kulimba.
Kutentha kwabwinobwino: mukatenthetsa mpaka pamwamba pa gawolo, sinthani kutentha, kuziziritsa bwino (mumlengalenga).
Annealing: mutatha kutentha mpaka pamwamba pa gawo losinthira kutentha, kenako kuziziritsa pang'onopang'ono.Chotsani zotsatira za kuzimitsa, kuthetsa kupsinjika maganizo, ndikuchotsani mawonekedwe a yunifolomu.
Kuwotcha: mutatha kuzimitsa, ndiye kutentha kwa kutentha kwina (pansi pa kutentha kozimitsa), kusunga kutentha, ndiyeno kuzizira.yunifolomu zikuchokera, pang`ono kuchepetsa kuuma, kwambiri kusintha kulimba.

Amagwiritsidwa ntchito kwambiri mu petroleum, mafakitale amafuta, potengera magetsi, boiler ndi mafakitale ena, popanga riyakitala, chotenthetsera kutentha, cholekanitsa, thanki yozungulira, thanki yamafuta ndi gasi, thanki yamafuta amadzimadzi, chipolopolo champhamvu chanyukiliya, ng'oma yowotchera, madzimadzi. silinda yamafuta ndi gasi, hydropower station high pressure water pipe, turbine volute ndi zida zina ndi zida.

Control rolling ndiyenso kugubuduza ulamuliro

Pamaziko a kusintha mankhwala zikuchokera zitsulo, ndi kulamulira Kutentha kutentha, anagubuduza kutentha, mapindikidwe dongosolo ndi magawo ena ndondomeko, ndi kulamulira kusintha lamulo la bungwe austenite ndi minofu mawonekedwe a gawo kusintha mankhwala, kuti akwaniritse cholinga. za kuyenga bungwe ndikuwongolera mphamvu ndi kulimba.
Control kugubuduza poyatsira wokhazikika ndi kulamulira anagubuduza, anagubuduza kutentha, kuthamanga voliyumu, kuzirala liwiro, komanso chomaliza anagubuduza kutentha ndi miyeso ina, kuti ntchito ya mbale zitsulo kukwaniritsa chiŵerengero chabwino cha mphamvu ndi kulimba.
Positive moto, wotchedwanso normalization, ndi zitsulo kutentha mankhwala ndondomeko kutentha workpiece kuti Ac 3 kapena Accm pamwamba 30 ~ 50 ℃, kuteteza kutentha kwa nthawi, kuchotsa ng'anjo mu mlengalenga kapena madzi kutsitsi, kutsitsi kapena kutsitsi. kuziziritsa mpweya.Kusiyana pakati pa moto wamba ndi kuziziritsa ndiko kuti liwiro lanthawi zonse loziziritsa moto limakhala lothamanga pang'ono kuposa liwiro loziziritsa, kotero kuti minofu yamoto yokhazikika imakhala yocheperako kuposa minofu yoziziritsa, komanso makina ake amawongoleredwa.Kuonjezera apo, kuzizira kunja kwa ng'anjo sikumakhala ndi zipangizo, zokolola zimakhala zazikulu, choncho kupanga kumagwiritsidwa ntchito m'malo mwa annealing momwe zingathere.
Kukula kwakukulu kwa moto ndi: ① pachitsulo chochepa cha carbon, moto utatha kuuma umakhala wokwera pang'ono kuposa kulimba, kulimba kulinso kwabwino, kungagwiritsidwe ntchito ngati kudula pokonzekera mankhwala. Kusintha kwa khalidwe monga chithandizo chomaliza cha kutentha, kungagwiritsidwenso ntchito ngati mankhwala okonzekera asanazimitse pamwamba ndi njira yotenthetsera kupatsidwa ulemu. kuti apeze dongosolo labwino lomwe limafunikira pakuzungulira kozungulira.④ Amagwiritsidwa ntchito popanga zitsulo, amatha kuyenga minofu yoponyera ndikuwongolera magwiridwe antchito. quenching.⑥ Pakuti ductile kuponyedwa chitsulo, kuti kulimba, mphamvu, kuvala kukana bwino, monga kupanga magalimoto, mathirakitala, injini dizilo crankshaft, ndodo yolumikizira ndi mbali zina zofunika. poyatsira, akhoza kuthetsa maukonde yachiwiri carburization, kuonetsetsa kuti onse carburization annealing.
