Cov khoom siv los ua cov khoom siv stainless hlau

 

Vim muaj kev siv sib txawv, txhua yam khoom muaj cov txheej txheem sib txawv thiab cov khoom siv raw khoom zoo. Feem ntau hais lus, cov khoom siv stainless hlau sib txawv yuav tsum muaj cov khoom siv raw thickness sib txawv. Piv txwv li, lub thickness kam rau ua ntawm Class II tableware thiab thermos khob feem ntau yog siab dua, ntawm -3~5%, thaum lub thickness kam rau ua ntawm Class I tableware feem ntau yuav tsum yog -5%, steel kav yuav tsum tau -10%, thiab thickness kam rau ua ntawm lub tsev so tub yees yuav tsum yog -8%. Lub thickness kam rau ua ntawm cov tswv lag luam feem ntau yuav tsum nyob nruab nrab ntawm -4% thiab 6%. Nyob rau tib lub sijhawm, qhov sib txawv ntawm kev muag khoom hauv tsev thiab txawv teb chaws yuav ua rau muaj kev sib txawv ntawm cov neeg siv khoom rau cov khoom siv raw thickness tolerances. Feem ntau, cov khoom lag luam xa tawm cov neeg siv khoom muaj qhov yuav tsum tau ua siab ntev dua, thaum cov tuam txhab muag khoom hauv tsev muaj qhov yuav tsum tau ua kom tuab tuab dua (feem ntau rau cov nqi txiav txim siab), thiab qee cov neeg siv khoom txawm xav tau -15%.
① DDQ (qhov tob tob tob) cov khoom siv: yog hais txog cov ntaub ntawv siv rau kev sib sib zog nqus nqus (txhaj), uas yog txhua tus neeg hu ua cov khoom muag. Cov yam ntxwv tseem ceeb ntawm cov khoom no yog siab elongation (Ntau dua los yog sib npaug rau 53%), qis hardness (Less tshaj los yog sib npaug rau 170%), sab hauv grain qib ntawm 7.0~8. 0, thiab kev ua haujlwm tob tob zoo heev. Ntau lub tuam txhab uas tsim cov thermos fwj thiab cov lauj kaub feem ntau muaj qhov ua tau zoo sib piv (BLANKING SIZE / cov khoom kab), uas yog 3.0, 1.96, 2.13, thiab 1.98 raws. SUS304DDQ cov ntaub ntawv feem ntau yog siv rau cov khoom lag luam uas xav tau kev ua haujlwm ntau dua. Tau kawg, cov khoom lag luam nrog kev ua piv txwv ntau dua 2.0 feem ntau xav tau ntau qhov kev sib tw kom tiav. Yog tias cov khoom siv raw elongation tsis ua tiav, cov khoom muaj feem ntau yuav tawg thiab rub los ntawm thaum ua cov khoom sib sib zog nqus, cuam tshuam rau tus nqi tsim nyog ntawm cov khoom tiav, thiab tau kawg nce tus nqi tsim khoom;
② Cov ntaub ntawv dav dav: feem ntau yog siv rau cov ntaub ntawv uas tsis yog DDQ lub hom phiaj. Cov yam ntxwv ntawm cov khoom no yog qhov qis elongation (Ntau dua lossis sib npaug li 45%) thiab cov tawv tawv (Less dua lossis sib npaug rau 180HB). Cov qhab-nees loj ntawm sab hauv yog nyob nruab nrab ntawm 8.0 thiab 9.0. Piv nrog rau DDQ cov ntaub ntawv, nws qhov kev sib sib zog nqus nqus qhov ua tau zoo yog qhov tsis zoo. Nws yog tsuas yog siv rau cov khoom uas tuaj yeem tau txais yam tsis muaj qhov ncab, xws li rab diav, diav rawg, cov khoom siv hluav taws xob, cov kav hlau, thiab lwm yam. Tab sis nws muaj qhov zoo dua cov khoom siv DDQ, uas yog, BQ kuj zoo, uas yog vim nws qhov me ntsis dua hardness.
Stainless hlau ntawv yog cov khoom siv nrog tus nqi qis, tab sis cov neeg siv khoom muaj qhov xav tau siab heev rau nws qhov zoo. Stainless hlau ntawv yuav inevitably muaj ntau yam tsis xws luag nyob rau hauv cov txheej txheem ntau lawm, xws li khawb, pitting, xuab zeb qhov, tsaus kab, creases, muaj kuab paug, thiab lwm yam., yog li nws nto zoo, xws li khawb, creases, thiab lwm yam., yog tsis pub nyob rau hauv. Cov ntaub ntawv qib siab, thiab pitting, xuab zeb qhov tseem tsis tau tso cai rau hauv kev tsim cov diav, diav rawg, vim tias nws nyuaj rau muab pov tseg thaum polishing. Nws yog ib qho tsim nyog los txiav txim siab qhov zoo ntawm qhov chaw raws li qhov degree thiab zaus ntawm ntau yam defects, thiaj li txiav txim siab cov khoom qib.
