Vim li cas cov hlau tsis muaj hlau ua thinner thaum ncab?
Hauv kev ua hlau, ncab txoj kev yog ib qho txheej txheem, tshwj xeeb tshaj yog thaum tsim stainless hlau ntxhua khaub ncaws, dab dej thiab cov khoom plhaub. Txawm li cas los xij, ntau tus neeg siv khoom yuav pom qhov tshwm sim hauv kev tsim khoom tiag tiag: stainless hlau yuav ua thinner thaum lub sij hawm ncab. Qhov no tsis yog ib qho teeb meem ntawm cov khoom zoo, tab sis ib qho tshwm sim ntawm cov yas deformation ntawm cov hlau. Kab lus no yuav coj koj mus rau qhov tob tob rau hauv cov txheej txheem tom qab qhov tshwm sim no.
I. Hlau stretching yog dab tsi?
Hlau Drawing (Drawing sib sib zog nqus) yog cov txheej txheem ntawm kev siv lub zog tensile rau lub phaj hlau los ntawm kev tuag los tsim ib qho qauv raws li cov duab ntawm cov tuag. Stainless hlau feem ntau siv rau hauv cov txheej txheem kos duab vim nws lub zog siab, zoo ductility thiab muaj zog corrosion kuj.
Ii. Vim li cas cov hlau tsis muaj hlau ua thinner thaum ncab?
1. Phab ntsa thickness thinning tshwm sim los ntawm cov khoom ntws
Thaum lub sij hawm stretching txheej txheem, thaum cov khoom siv hlau yog rub los ntawm lub phaj mus rau hauv qhov tuag kab noj hniav, ntau qhov chaw ntawm cov khoom yuav tsum tau "ntws" kom haum rau cov duab ntawm cov tuag. Thaum lub sij hawm tus txheej txheem no, cov khoom yuav raug kev nyuaj siab nyob rau hauv ntau yam lus qhia. Tshwj xeeb tshaj yog nyob rau sab phab ntsa cheeb tsam, cov hlau yog stretched tab sis tsis replenished txaus, uas ua rau ib tug thinning ntawm phab ntsa thickness.
2. Cov yam ntxwv ntawm cov yas deformation txiav txim siab tias "elongation ua rau thinning".
Thaum cov hlau raug yas deformation, lawv qhov ntim tseem nyob tas li. Uas yog hais tias, thaum lub sij hawm ntev ntawm stainless hlau daim hlau nce thiab qhov tob tob thaum lub sij hawm stretching txheej txheem, qhov dav los yog thickness yuav tsum txo raws li. Qhov no yog ib txoj cai ntawm kev txuag cov ntaub ntawv.
3. Cov cheeb tsam kev ntxhov siab yog qhov feem ntau ua rau thinning
Feem ntau, nyob rau hauv cov ces kaum sib npaug los yog qhov chaw hloov pauv ntawm sab phab ntsa thiab hauv qab, lub zog muaj zog tshaj plaws, kev sib txhuam tsis sib haum yog loj, thiab cov hlau deformation yog qhov hnyav. Yog li ntawd, cov cheeb tsam no feem ntau yog qhov chaw uas thinning yog pom tseeb tshaj plaws.
4. Cov nyhuv hardening ntawm stainless hlau nws tus kheej
Stainless hlau muaj cuab kev ua hauj lwm hardening yam ntxwv, uas yog, nws maj hardens thiab ua brittle thaum lub sij hawm deformation txheej txheem. Thaum cov hlau tsis ntws mus rau hauv qhov chaw deformation nyob rau hauv lub sij hawm thaum lub sij hawm pib ncab theem, kev ntxhov siab hauv zos yuav tshwm sim, ntxiv rau hauv zos thinning.
Iii. Yuav ua li cas tswj lub thinning phenomenon ntawm stainless hlau?
Txhim kho pwm tsim: Tsim nyog tsim lub vojvoog fillet, qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Xaiv cov ntaub ntawv tsim nyog: Piv txwv li, siv cov ntaub ntawv uas tsis tshua muaj hardening Performance index xws li 304L los yog 430 los txhim kho cov uniformity ntawm deformation.
Kev kho ua ntej-lubrication: Kev siv cov roj nplua nyeem tuaj yeem txo cov coefficient ntawm kev sib txhuam thiab txo qhov kev pheej hmoo ntawm cov hlau tawg thiab hauv zos thinning.
Siv ntau- txheej txheem kev kos duab: Rau cov khoom sib sib zog nqus nqus cov khoom, ua ntej- kos duab thiab kos duab zaum kawg yog ua raws cov kauj ruam kom qeeb deformation tus nqi thiab kev ntxhov siab concentration.
4. Cov lus xaus
Lub thinning ntawm stainless hlau thaum lub sij hawm ncab yog ib qho tshwm sim thiab tswj tau nyob rau hauv cov hlau yas ua. Los ntawm kev tsim qauv tsim nyog thiab kev tswj xyuas cov txheej txheem, qib ntawm thinning tuaj yeem tswj tau nyob rau hauv qhov tsim nyog ntau yam thaum ua kom muaj kev tsim cov khoom zoo. Kev nkag siab txog qhov no pab cov neeg siv khoom siv cov nyiaj thickness thiab formability mus rau hauv tus account thaum ntxov ntawm cov khoom tsim, kom ntseeg tau tias qhov kev vam meej ntawm ntau lawm.
