Dab tsi ntsuas tuaj yeem coj los txhim kho lub hardness ntawm st13 steel phaj yog tias nws tsawg dhau?
Thaum lub hardness ntawm st13 steel phaj tsawg dhau, ntsuas cov kev ntsuas hauv qab no tuaj yeem ua, nyob ntawm cov txheej txheem ntau lawm, kom tau raws li cov khoom siv stamping:
1. Kho cov txheej txheem anealing (rau cov tuam ntxhab)
Txo qhov kub thiab txias lossis ua kom luv lub sijhawm tuav: St13 steel yog feem ntau annealed kom txo tau hardness. Yog tias lub hardness tsawg dhau, qhov kev kub ntxhov ntau dhau tuaj yeem raug txo qis (piv txwv, los ntawm 700-710℃los ntawm kev tswj cov txheej txheem recrystallization.
Ua kom zoo dua tus nqi txias: tsim nyog nrawm nrawm nrawm dua) tuaj yeem ua rau cua txias dua tshiab) tuaj yeem ua rau muaj pa taws ntau ntxiv thiab ua rau muaj kev nyuaj me ntsis.
2. Ntxiv lub teeb txias dov (rau kev ua)
Cov phiaj hlau hlau nrog cov hardness qis yog raug rau ib lub teeb cleing cleing Hom no yooj yim rau kev ua haujlwm thiab tsim nyog rau cov khoom me me, vim qhov no yuav txo cov plastentive cov plastent lub plastently thiab cuam tshuam rau kev ua tau zoo.
3. Xaiv cov khoom siv raw (tswj cov chaw)
Yog tias muaj hardness bityists nyob rau lub sijhawm, cov tuam txhab tsim khoom tuaj yeem hloov kho cov ntsiab lus manganes thiab siliciar Qhov no tuaj yeem txhim kho lub zog matrix los ntawm cov khoom siv daws teeb meem zog thiab tsis ncaj ncees txhim kho lub hardness.
4. Adapting cov txheej txheem tsis sib xws (rau cov txheej txheem stamping)
Yog tias kho cov tawv tawv ntawm cov hlau phaj nws tus kheej yog tsis tau, cov txheej txheem stamping tawm los ntawm cov khoom siv tsis txaus ntseeg los tiv thaiv kev tiv thaiv wrinkles thaum nthuav dav. Cov nyiaj them rau cov txheej txheem no tuaj yeem daws qhov teeb meem ntawm kev tawv tawv qis.
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev ntsuas no yuav tsum tau ua nyob rau hauv cov qauv kev ua tau zoo uas tuaj yeem txo cov ntsiab lus tseem ceeb xws li kev cuam tshuam, yog li cuam tshuam cov txheej txheem stamping. Hauv kev ua haujlwm tiag tiag, nws raug nquahu kom paub tseeb cov nyhuv los ntawm me me- nplai kuaj ua ntej thov nws hauv batches.
