Lub koob yees duabyog ib qho ntawm cov yam ntxwv tseem ceeb ntawm lubtshuab knitting voj voog, nws lub luag haujlwm tseem ceeb yog tswj kev txav ntawm rab koob thiab lub dab dej thiab daim ntawv ntawm kev txav mus los, tuaj yeem faib ua rab koob (rau hauv lub voj voog) cam, ib nrab tawm ntawm rab koob (teem lub voj voog) cam, rab koob tiaj tus (kab ntab) cam thiab lub dab dej cam.
Lub koob yees duabntawm qhov zoo tag nrho ntawm qhov siab thiab qis,cov tshuab knitting voj voogthiab cov ntaub yuav muaj kev cuam tshuam loj heev, yog li ntawd, thaum yuav cov cams yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no.
Ua ntej tshaj plaws, rau cov ntaub sib txawv thiab cov ntaub xav tau los xaiv cov ntaub sib xwslub koob yees duabnkhaus. Vim tias tus tsim qauv ntawm cov ntaub npuag nrhiav kev sib txawv, sib txawv qhov tseem ceeb, yog li ntawd lub cam ua haujlwm nto nkhaus yuav txawv.
Vim yog lub koob los yog lub dab dej thiablub koob yees duablub cim ntev ntawm kev sib txhuam ceev ceev, cov ntsiab lus ntawm cov txheej txheem tib lub sijhawm kuj yuav tsum tiv taus qhov cuam tshuam siab, yog li ntawdlub koob yees duabKev xaiv ntawm daim pib hauv tebchaws Cr12MoV, cov khoom siv yog qhov zoo hardenability, hluav taws deformation, hluav taws deformation, hluav taws hardness, lub zog, toughness yog qhov tsim nyog dua rau lub cam xav tau.Lub koob yees duabQhov nyuaj ntawm quenching feem ntau yog HRC63.5 ± 1. Qhov nyuaj ntawm cam yog siab dhau lossis qis dhau yuav muaj cov teebmeem tsis zoo.
Lub koob yees duabQhov roughness ntawm qhov nkhaus yog qhov tseem ceeb heev, nws yeej txiav txim siab seb qhovlub koob yees duabzoo thiab ruaj khov.Lub koob yees duabQhov nkhaus ntawm qhov chaw roughness, yog los ntawm cov khoom siv ua haujlwm, cov cuab yeej, cov txheej txheem ua haujlwm, kev txiav thiab lwm yam ntsiab lus ntawm qhov kev txiav txim siab (tus nqi ntawm cov tuam txhab tsim khoom cam qis heev, feem ntau yog nyob rau hauv qhov txuas no los ua cov ntawv xov xwm).lub koob yees duabQhov nkhaus ua haujlwm thiab qhov roughness feem ntau yog txiav txim siab raws li Ra ≤ 0.8um. Qhov roughness ntawm qhov chaw ua haujlwm tsis ua tiav zoo yuav ua rau lub pob taws ntawm rab koob sib tsoo, ntaus rab koob, lub rooj zaum ces kaum cua sov thiab lwm yam xwm txheej.
Tsis tas li ntawd xwb, tab sis kuj yuav tsum tau them sai sai rau qhov chaw ntawm lub qhov cam, txoj kev tseem ceeb, cov duab thiab qhov nkhaus ntawm qhov chaw sib piv thiab qhov tseeb, cov kev saib xyuas no yuav tsis ua rau muaj kev phiv.
