Txhawm rau tswj kev ua lag luam, xyuas kom muaj kev ruaj ntseg ntawm kev lag luam kev lag luam thiab tsis txhob muaj kev sib tw tsis ncaj ncees, kev tswj xyuas tus nqi rau kev lag luam kho cua sov tau tsim. Qhov kev xav no yog siv dav hauv cov lus hais txog kev kho cua sov ntawm cov khoom me me thiab yog lub hauv paus tseem ceeb rau cov lus hais txog kev kho cua sov ntawm cov khoom me me.
1, Tus nqi ua haujlwm ntawm kev kho cua sov
Cov nqi ua haujlwm ntawm kev kho cua sov feem ntau yog siv lub zog siv hluav taws xob, cov khoom siv pabcuam, cov nqi zog thiab lwm yam. Hauv cov txheej txheem kev kho cua sov, kev siv hluav taws xob yooj yim thiab kev siv hluav taws xob siv hluav taws xob yooj yim raug coj los ua tus lej xov tooj, thiab suav nrog cov yam ntxwv ntawm ntau yam txheej txheem kev kho cua sov thiab kev ua haujlwm. Cov mis laij lej yuav tsum tau xa mus rau qhov kev ntsuas ntsuas ntsuas qhov ntsuas thiab kev tswj hwm kev lag luam kho cua sov:
Kev siv hluav taws xob yooj yim=tus qauv siv hluav taws xob siv hluav taws xob * kev hloov pauv txheej txheem coefficient * cua sov hom coefficient * hom ntau lawm coefficient * cov khoom siv coefficient * loading coefficient
2, Quotation ntawm kev ua technology cov ntsiab lus
Cov txheej txheem thev naus laus zis tau paub los ntawm Han Dynasty raws li qib thev naus laus zis lossis qib kev ua haujlwm ntawm cov txheej txheem ua tiav. Cov qib kev kawm feem ntau muab faib ua peb theem: siab, nruab nrab thiab qis.
Advanced: nws tsuas yog siv cov khoom tseem ceeb xws li cov cuab yeej thiab tuag, spindles thiab cov lus qhia kev ua tiav los ntawm lub tshuab nqus tsev lossis laser, nrog cov coefficient ntawm 1.5.
Intermediate: ntau yam khoom siv ntawm cov cua sov kho cua sov, ion nitriding, roj nitriding, mos nitriding, siab thiab nruab nrab zaus, nrog cov coefficient ntawm 1.2.
Qib qis: quenching thiab tempering, normalizing, annealing, zoo hom furnace carburization, ntsev da dej rauv quenching, thiab lwm yam ntawm cov khoom siv dav dav, nrog cov coefficient ntawm 1.0.
