Yuav ua li cas cov hlau nplaum ntawm 304 stainless hlau los ntawm? Tus editor yuav muab rau koj ib tug refresher: nyob rau hauv lub smelting los yog forging txheej txheem, tivthaiv cais los yog kev kho cua sov tsis zoo yuav ua rau ib tug me me ntawm martensite los yog ferrite qauv nyob rau hauv 304 stainless hlau phaj. Yog li, 304 stainless hlau phaj yuav muaj zog hlau nplaum. Tsis tas li ntawd, lub microstructure ntawm 304 stainless hlau phaj tseem yuav hloov mus rau martensitic stainless hlau tom qab ua haujlwm txias. Qhov ntau dua qhov kev ua haujlwm txias deformation, qhov hloov pauv martensitic ntau dua ntawm 304 stainless hlau phaj, thiab ntau dua cov hlau nplaum.
Cov qauv austenite tuaj yeem rov qab los thiab sib sau ua ke los ntawm kev kho cov khoom kub kub (tso cua sov cov hlau mus rau qhov kub siab ib-theem cheeb tsam qhov kub thiab txias qhov sib txuas, yog li ntawd cov theem siab tshaj yog tag nrho yaj hauv cov khoom tov thiab tom qab ntawd txias kom tau txais supersaturated. cov txheej txheem kho cua sov txheej txheem) los kho thiab sib sau cov qauv austenite, yog li tshem tawm cov hlau nplaum. Cov txheej txheem ntxaws: cua sov 304 stainless hlau phaj rau 1050 ° C, thiab quenching nrog dej txias yog qhov zoo ntawm carburizing cov carbides hauv 304 stainless hlau phaj. Txoj kev no yog tsim rau workpieces uas xav tau kev kho cua sov thiab workpieces tom qab vuam. ②Siv ib qho chaw sib nqus sib nqus: Demagnetize nws nrog lub DC vuam tshuab uas tig rau: Clamp ib tug vuam tongs ntawm lub vuam tshuab rau ib kawg ntawm cov khoom, thiab ces siv lwm welding tongs rau qhov opposite kawg ntawm 304 stainless hlau. phaj. Maj mam txo qis, thiab tuaj yeem muab faib ua ob peb zaug; tab sis lub sij hawm tsis tuaj yeem ntev dhau, tus naj npawb ntawm lub sij hawm tsis tuaj yeem ntau dhau, txwv tsis pub nws yooj yim los rhuav tshem lub tshuab vuam.
Cov txheej txheem kev txhawb nqa rau 304 stainless hlau phaj txuas yuav tsum ruaj khov thiab tiaj tus, thiab txhawm rau kom ntseeg tau tias lub vaj huam sib luag stainless hlau yooj yim los hloov thiab nruab, qhov txheej txheem ntawm cov hanging phaj npaj ua ib chav me me yog tej zaum los ntawm daim ntawv. buckle, thiab stainless hlau phaj tsuas yog buckled los ntawm qhov profile. Txhawm rau ua tiav qhov txuas ntxiv thiab kho nrog lub hauv paus ntsiab lus. Feem ntau siv kev txhawb nqa ntawm cov hlau tsis muaj steel veneers rau kab hlau rhuav phab ntsa yog muab faib ua: txiav board, buckle layout thiab lub thawv layout. Lub rooj tsavxwm txiav tau tsa cov npoo thiab cov kaum ntawm lub rooj tsavxwm zoo li, tab sis lub rooj tsavxwm stainless hlau yog hloov tau thiab tsim nyog rau cov khoom siv qis lossis qis cua siab; lub buckle layout yog haum rau nyias stainless hlau veneers, thiab cov flatness yuav tsum tsis siab, uas yog zoo rau kev nkag siab ntawm cov pov thawj thiab kev ntxhib los mos. Tej yaam num uas yuav tsum muaj siab rau cov khoom siv los soj ntsuam cov teebmeem tuaj yeem txais tau; lub thawv-zoo li tus txheej txheem tsa qhov kev ruaj ntseg ntawm lub thav duab kev txhawb nqa, uas yog tsim rau cov khoom siv siab, muaj zog cua tsis kam, thiab tuaj yeem nthuav tawm cov khoom siv txawv txawv ntawm cov hlau tsis muaj steel, yog li nws tau txais dav.
