● Kev kho cua sov cov txheej txheem ntawm cov cuab yeej carbon hlau
Cov txheej txheem kev kho cua sov ntawm cov cuab yeej siv hlau ua nrog kev siv cov hlau-carbon alloy theem daim duab, thiab cov txheej txheem kev kho cua sov yog yooj yim. Cov kev tsis zoo yog qhov ua kom lub cev tsis tshua tawv, muaj qhov me me thiab qhov kub thiab txias, muaj qhov txawv txav tom qab quenching, lub cev tsis zoo, yooj yim tawg thaum lub sijhawm quenching, thiab tsawg dua kev siv txias txias tuag nrog qhov siab qhov tseeb qhov yuav tsum tau, loj muaj peev xwm loj thiab cov duab puab.
● Kev kho cua sov cov txheej txheem ntawm qhov tsis tshua muaj alloy txias ua haujlwm tuag steel
High-carbon tsawg-alloy txias ua haujlwm tuag steel muaj siab hardenability, hnav tsis kam, toughness thiab kev pab lub neej. Cov txheej txheem kev kho cua sov rau cov khoom siv pwm no nrog cov khoom loj loj thiab cov txheej txheem cov txheej txheem muaj teeb meem yog qhov ntsuas kub tsis tshua kub thiab ntxiv rau nruab nrab kub ntsev da dej quenching.
● Kev kho cov cua sov ntawm high alloy txias ua haujlwm tuag steel
High-alloy txias ua haujlwm tuag hlau (xws li Cr12 tuag steel, Cr12MoV tuag steel, thiab lwm yam) rau cov khoom lag luam bainite steel thiab muaj ntau cov khoom siv ua haujlwm eutectic carbide. Vim tias cov khoom siv raw cov ntaub ntawv muaj ntau cov kab xev lossis zoo li cov qauv sib xyaw, qhov khoob yuav tsum tau ua rau Forging tau rov ua dua, thiab tom qab ntawd spheroidizing annealing tau ua tom qab quenching ntawm 1200 ° C. Cov qauv no tuaj yeem txhim kho qhov tawv ntawm cov hlau, thiab nws kuj tseem tuaj yeem ua tus qauv quenched zoo.
● Kev kho cov cua sov txheej txheem ntawm cov siab ceev steel
Vim tias kev kub ceev steel belongs rau cov hlau martensitic, nws muaj lub siab hardness, compressive zog thiab hnav tsis kam. Yog li no, qis kub quenching thiab tempering feem ntau siv hauv kev lag luam txhawm rau txhim kho nws cov yam ntxwv lub cev. Tus qauv tempered yog tempered martensite, Alloy carbides thiab me me ntawm cov khaws austenite. Txhawm rau kom txo qis ntau npaum li cas austenite, ntau qhov kev npau taws yuav tsum tau ua kom tshem tawm cov austenite khaws cia.
● Thaum tshav kub kub kho txheej txheem ntawm cemented carbide
Vim tias cemented carbide yog hmoov ua hlau nrog ib tus nplaum, forging thiab kho cua sov tsis tuaj yeem siv los txhim kho nws cov txheej txheem kev ua haujlwm.
Raws li kev txheeb xyuas saum toj no thiab peb ib txwm ua haujlwm thiab kev paub dhau los, nws tuaj yeem pom tias cov yam tseem ceeb cuam tshuam rau kev pab cuam lub neej ntawm kev tuag yog kev ua haujlwm ntawm kev tuag, kev ua haujlwm ntawm cov pam tuag, daim ntawv ua tsis tiav, cov txheej txheem kev kho cua sov ntawm cov tuag, thiab cov kev xaiv ntawm cov ntaub ntawv tuag. Yog li, kev txheeb xyuas ntawm daim ntawv tsis ua tiav ntawm qhov punching tuag, ua ke nrog kev xaiv tsim nyog ntawm kev tuag steel thiab kev txhim kho ntawm cov txheej txheem kev kho cua sov, tuaj yeem ua tiav zoo rau ntau yam zoo kawg nkaus ntawm cov punching tuag thiab tuag steel, yog li kev txhim kho ntxiv kev pab cuam lub neej tuag.
