Yog tias peb saib ibStainless Hlau BoltQhov ntawd qhia tau tias tsis pom cov teeb meem zoo nrog lub qhov muag liab qab ntawm lub khob tsom iav, peb yuav pom pom tseeb porosity ntawm cov ntsia liaj qhov ntses. Thaum muaj mob hnyav heev, muaj tej zaum yuav muaj huab cua -}} pob puv npuas thiab dawb me ntsis. Cov no yog qhov ua rau ncaj qha ntawm subustard lub zog hauv cov hlau steel bolts, uas peb hais txog raws li porosity thiab segregation yam tsis xws li hauv cov qauv khoom siv.
Nyob rau hauv cov hauj lwm muaj, kev pab ntawm stainless hlau bolts tau mus txog kwv yees li 30% ntawm tag nrho cov khoom lag luam fastener thiab txuas ntxiv nce. Txhawm rau kom ntseeg tau tias kev siv hluav taws xob thiab ruaj khov ntawm stainless hlau bolts, nws yog ib qho tsim nyog los txais yuav yooj yim dhau tsis yog- cov teeb meem zoo. Txoj kab sib cais tsis xws luag hais saum toj no yog ib qho teeb meem no.
Ua ntej tsim khoom, cov khoom siv rau stainless hlau bolts undergoes cov txheej txheem xws li txias dov, pickling, thiab polishing. Qee cov ntaub ntawv, tom qab sib tsoo ntxhib, yuav tsum tau nplua xuab zeb sib tsoo kom tshem tawm saum npoo burrs, kom ntseeg tau qhov ua kom zoo nkauj ntawm cov hlau steelness. Lub porosity tau hais txog ntawm no yog hais txog qhov kev sib cav tsis txaus ntawm cov khoom, feem ntau tshwm sim los ntawm kev sib txuam ntau dhau ntawm kev ua tsis tau zoo. Nyob rau lub sijhawm, corrosion yuav maj mam ua rau kev tsim cov npuas. Yog tias qhov tshwm sim no tshwm sim rau ntawmBolt'sHla -} section section, qhov cuam tshuam yog tus menyuam yaus; Yog tias nws tshwm sim hauv qhov chaw ntev ntawm cov ntsia liaj qhov rooj shank, nws qhia tau tias porosity yuav tau tsim nyob rau hauv lub ntsia liaj qhov chaw. Nyob rau hauv cov xwm txheej zoo li no, kev soj ntsuam kev tshaj lij kev txawj ntse yog xav tau los ntsuas qhov ntsuas ntawm lub zog puas.
Yog li, dab tsi yog segregation? Tsuas yog muab tso, nws yog qhov tsis sib xws faib ntawm ntau yam hauv cov khoom siv. Pom nyob rau hauv lub tshuab tsom, tus qauv sab hauv ntawm cov khoom muaj kev ntxhov siab, hos ua tsaug rau kev cais tawm hauv Suav, dot} zoo li kev cais tawm tau ua tsawg. Qhov kev faib tawm denditic feem ntau tshwm sim los ntawm qhov kub hloov thaum lub sij hawm cov khoom siv: thaum cov khoom kub sib txawv tshwm sim ntawm kev sib txawv; Raws li qhov kub me hloov dua, cov kab tshiab txuas los ntawm thawj kab sib cais, nws thiaj li tsim cov qauv dendritic. Txawm hais tias kev cais tawm yog ib qho tshwm sim thiab tsis tuaj yeem tshem tawm tag nrho, ntau dhau ntawm cais cais yuav cuam tshuam rau lub zog.
Cov npuas thiab cov ntxig uas muaj me me yog cov kab me me tsim thaum lub sijhawm khoom siv. Ob peb tus neeg npuas yog li qub, tab sis honeycomb - zoo li npuas tau muab qhov teeb meem zoo. Nruam qhov kub hloov ua rau qhov sib txawv me ntsis hauv lub sijhawm sib txawv ntawm ntau lub sijhawm ua lead ua hauv cov khoom. Yog tias suav nrog nyob rau hauv cov khoom siv, lawv yuav ua kom dawb me ntsis lossis npuas. Ntxiv rau qhov ntsuas kub hloov pauv, qhov tsim ntawm npuas yog feem ntau cuam tshuam nrog kev suav nrog hauv cov khoom. Bolt cov ntaub ntawv yog tsim los ntawm smelting ntau alloys ntawm qhov kub. Sib txawv alloys muaj cov ntsiab lus sib txawv; Thaum lub sij hawm smelting, alloys nrog siab dua melting cov ntsiab lus zoo li tawm ntawm cov chaw seem tsis muaj tseeb, uas nyob rau hauv kev hloov bubbles. Yog li ntawd, qhov chaw smelting rau cov khoom siv sib tw yog qhov tseem ceeb heev. Ib qho yuav tsum tsis quav ntsej txog cov nyom tsis zoo nyob rau hauv ib puag ncig tsuas yog ua tau feem ntau ua rau ib puag ncig yog qhov ua rau muaj teeb meem zoo.
Thaum muaj mob hnyav, cov ntsia liaj qhov rooj nto si tsis tsuas muaj cov pob dawb xwb tab sis kuj pom tseeb. Cov kab nrib pleb muaj qhov cuam tshuam loj tshaj plaws ntawm cov neeg ua haujlwm ntawm cov khoom siv ntawm bolts thiab tau raug txwv kiag li nyob rau hauv cov khoom smelting. Txhawm rau kom tsis muaj kab nrib pleb
Hauv cov ntsiab lus, cais, cov pob dawb, thiab cov kab nrib pleb yog txhua yam teeb meem tsis tsim nyog rau cov hlau steel bolts. Cov teeb meem zoo no yuav tsum tau tswj hwm los ntawm kev txiav txim siab nruj nruj nruj me ntsis thaum cov khoom nkag mus rau lub Hoobkas. Tsuas yog los ntawm kev ua ntej zoo tuaj yeem ua lag luam ua tiav lub suab kev txhim kho suab.
