Cov txheej txheem tsim cov raj xa dej tsis xeb

Txias dov:nws yog qhov ua tiav ntawm kev siab thiab ncab ductility. Smelting tuaj yeem hloov cov tshuaj lom neeg ntawm cov khoom siv hlau. Txias dov tsis tuaj yeem hloov cov tshuaj lom neeg ntawm cov hlau, lub kauj yuav raug muab tso rau hauv cov khoom siv txias dov dov siv cov siab sib txawv, lub kauj yuav txias dov rau ntau qhov tuab sib txawv, thiab tom qab ntawd los ntawm qhov kawg dov tiav, tswj qhov tseeb ntawm lub kauj tuab, qhov tseeb dav dav hauv 3 silk.

 

Kev Kub Hnyiab:Cov kauj vuam txias raug muab tso rau hauv lub cub tawg annealing, cua sov rau qee qhov kub (900-1100 degrees), thiab qhov ceev ntawm lub cub tawg annealing raug kho kom tau qhov nyuaj tsim nyog. Cov khoom siv yuav tsum mos, qhov ceev annealing qeeb, qhov siab dua tus nqi sib xws. 201 thiab 304 yog austenitichlau tsis xeb, nyob rau hauv cov txheej txheem annealing, qhov xav tau kub thiab txias los kho lub koom haum metallurgical ntawm cov txheej txheem txias dov raug puas tsuaj, yog li annealing yog qhov txuas tseem ceeb heev. Qee lub sijhawm annealing tsis zoo txaus los tsim xeb yooj yim.

 

Cov khoom ua haujlwm raug cua sov rau qhov kub uas tau teem tseg, tuav rau ib lub sijhawm thiab tom qab ntawd maj mam txias cov txheej txheem kho cua sov hlau. Lub hom phiaj ntawm annealing yog:

1 los txhim kho lossis tshem tawm cov hlau hauv cov txheej txheem casting, forging, dov thiab vuam uas tshwm sim los ntawm ntau yam kev teeb tsa tsis zoo thiab kev ntxhov siab seem, los tiv thaiv cov workpiece deformation, tawg

2 ua kom lub workpiece mos rau kev txiav.

3 ua kom cov nplej zoo, txhim kho lub koom haum kom txhim kho cov khoom siv kho tshuab ntawm cov khoom ua haujlwm. Kev npaj lub koom haum rau kev kho cua sov kawg thiab kev ua yeeb nkab.

 

Kev txiav:Cov hlau tsis xeb, txiav rau hauv qhov dav sib xws, yog li ua kom tiav cov txheej txheem sib sib zog nqus ntxiv thiab ua yeeb nkab, cov txheej txheem txiav yuav tsum tau them sai sai rau kev tiv thaiv, kom tsis txhob khawb lub kauj, qhov dav thiab qhov yuam kev, ntxiv rau kev txiav cov kev sib raug zoo ntawm cov txheej txheem ua yeeb nkab, kev txiav ntawm cov hlau strip tshwm sim ntawm cov khoom ntawm pem hauv ntej thiab burrs, chipping ncaj qha cuam tshuam rau cov txiaj ntsig ntawm cov yeeb nkab welded.

 

Vuam:Cov txheej txheem tseem ceeb tshaj plaws ntawm cov yeeb nkab stainless hlau, feem ntau yog siv argon arc welding, high frequency welding, plasma welding, thiab laser welding. Tam sim no feem ntau siv argon arc welding.

Argon arc vuam:Cov roj tiv thaiv yog cov roj argon ntshiab lossis cov roj sib xyaw, qhov zoo ntawm kev vuam, kev ua tau zoo ntawm kev vuam, nws cov khoom lag luam hauv kev lag luam tshuaj lom neeg, nuclear thiab zaub mov siv dav.

Kev vuam zaus siab:Nrog rau lub zog fais fab siab dua, rau cov ntaub ntawv sib txawv, sab nraud ntawm phab ntsa tuab ntawm cov yeeb nkab hlau tuaj yeem ua tiav qhov ceev vuam siab dua. Piv nrog argon arc vuam, nws qhov ceev vuam siab tshaj plaws yog ntau dua 10 npaug. Piv txwv li, kev tsim cov yeeb nkab hlau siv cov vuam zaus siab.

Plasma vuam:Muaj lub zog nkag mus tob heev, yog siv cov plasma torch tshwj xeeb uas tsim los ntawm cov plasma arc kub siab, thiab nyob rau hauv kev tiv thaiv ntawm cov roj fusion hlau vuam txoj kev. Piv txwv li, yog tias cov khoom tuab txog 6.0 hli lossis ntau dua, plasma welding feem ntau yuav tsum tau ua kom ntseeg tau tias qhov vuam seam yog welded los ntawm.

Cov yeeb nkab tsis xeb hlauNyob rau hauv lub raj plaub fab, lub raj plaub fab, lub raj oval, lub raj zoo li tus, pib los ntawm lub raj puag ncig, los ntawm kev tsim cov raj puag ncig nrog tib lub voj voog thiab tom qab ntawd tsim rau hauv cov raj zoo sib xws, thiab thaum kawg shaping thiab ncaj nrog pwm.

Cov txheej txheem txiav cov yeeb nkab stainless hlau yog qhov nyuaj heev, feem ntau ntawm lawv raug txiav nrog cov hniav hacksaw, qhov txiav yuav tsim cov khoom me me ntawm pem hauv ntej; lwm qhov yog txiav nrog band saw, piv txwv li, cov yeeb nkab stainless hlau loj, kuj tseem muaj cov khoom ntawm pem hauv ntej, feem ntau cov khoom ntawm pem hauv ntej ntau dhau thaum cov neeg ua haujlwm xav tau hloov cov hniav pom.

Kev txhuam: Tom qab ua tiav cov yeeb nkab, qhov chaw yuav tsum tau txhuam los ntawm lub tshuab txhuam. Feem ntau, muaj ntau txoj hauv kev rau kev kho qhov chaw ntawm cov khoom thiab cov yeeb nkab kho kom zoo nkauj, txhuam, uas muab faib ua cov xuab zeb ci (daim iav), 6K, 8K; thiab kev txhuam yog muab faib ua xuab zeb puag ncig thiab xuab zeb ncaj, nrog 40 #, 60 #, 80 # 180 #, 240 #, 400 #, 600 #, kom tau raws li cov kev xav tau sib txawv ntawm cov neeg siv khoom.
