Inta badan loo isticmaalo wax soo saarka ee kala duwan oo caliber bir bir ah oo aan kala go 'lahayn iyo xaashida.



15CrMo Codsiyada:



 Tubta ugu muhiimsan ee uumiga ee xuduudaha uumiga 510 ° C, 530 ° C xuduudaha uumiga tuubooyinka kulaylka sare ee kuleyliyaha, kateetarka iyo madaxa uumiga cadaadiska sare, ka dib deminta iyo heerkulka, heerkulka qolka waxaa loo isticmaali karaa in lagu soo saaro qaybo kala duwan oo muhiim ah oo shaqada ah.

Daawaynta kulaylku waa qiyaas aad wax ku ool ah oo lagu wanaajinayo oo wax looga beddelayo sifooyinka birta wareegsan ee 15CrMo. Waxay ka ciyaartaa door aad muhiim u ah isku halaynta alaabta iyo dhaqaalaha. Daawaynta kulaylka ee birta wareega ee 15CrMo waxaa ka mid ah daaweynta kulaylka caadiga ah (jidhid, caadi ka dhigid, demin, dabci) iyo daawaynta kulaylka dusha sare (deminta dusha sare iyo daawaynta kulaylka kiimikaad-carburizing, nitriding, metalizing, iwm.).

Injineerinka farsamada, qaybo badan oo mishiin ah, sida crankshafts, gears, camshafts matoorada gubashada gudaha, iyo gears ee yareeyayaasha muhiimka ah, ma aha oo kaliya waxay u baahan yihiin adkeysi ku filan, caag iyo xoog laabasho ee xudunta, laakiin sidoo kale waxay u baahan yihiin dhumuc sare oo dusha sare ah gudaha dhumuc gaar ah. . Adag, caabbinta xidhashada sare iyo xoogga daalka sare. Hababka daaweynta kulaylka ee kala duwan ee aan soo sheegnay way adag tahay in la buuxiyo shuruudaha kor ku xusan ee kor ku xusan isla mar ahaantaana, iyo isticmaalka daaweynta kulaylka dusha sare waa habka ugu waxtarka badan ee lagu gaaro shuruudaha waxqabadka isku mar.

Daawaynta kulaylka dusha sare waa hab daawaynta kulaylka oo bedesha sifooyinka dusha sare ee birta wareegsan ee 15CrMo alloy iyadoo la beddelayo qaab dhismeedka lakabka sare.
Deminta dusha sare waa daawaynta kulaylka oo beddesha qaab-dhismeedka dusha mid mid iyada oo aan la beddelin isku-dhafka kiimikada ee dusha sare. Waxaa lagu xaqiijin karaa soo noqnoqoshada sare, soo noqnoqoshada dhexdhexaadka ah ama habka kuleyliyaha soo noqnoqda ee hadda jira ama habka kuleylka ololka. Habka caadiga ah waa in dusha sare ee birta wareega ee 15CrMo si degdeg ah loo kululeeyo heerkulka deminta, iyo marka kulaylka aan loo wareejin xudunta qaybta, si dhakhso ah ayaa loo qaboojiyaa, si ay u adkaato dusha sare, laakiin xudunta udubdhexaadka ah ayaa wali leh adayg sare.

Daawaynta kiimikadu waa hab lagu daweeyo kulaylka taas oo bedesha isku dhafka kiimikada iyo qaab dhismeedka lakabka sare ee birta wareegsan ee 15CrMo alloy Daawaynta kulaylka kiimikaad waxaa loo qaybin karaa habab ay ka mid yihiin carburizing, nitriding, carbonitriding, iyo metalizing iyadoo la raacayo canaasiirta kala duwan ee la soo dhex galiyay dusha sare ee 15CrMo daawaynta birta wareegsan. Aad bay waxtar u leedahay hagaajinta iyo hagaajinta caabbinta xidhashada, iska caabinta daxalka iyo iska caabbinta daalka ee 15CrMo alloy birta wareegsan. Waqtigan xaadirka ah, daaweynta kulaylka kiimikada ayaa si degdeg ah u horumaray, waxaana jira codsiyo badan oo tiknoolajiyada cusub ah.
