Dab tsi yog cov txheej txheem tsim khoom rau cov hlab ntsha siab?

I. Cov txheej txheem tsim khoom loj

1. Raw Material Txais thiab ua ntej- kho

Tom qab cov hlau tuaj txog ntawm qhov chaw, nws yuav tsum tau txais cov khoom siv rov qab- tshuaj xyuas kom paub meej tias nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ua tau raws li cov qauv tsim.

Ua ntej- kev kho mob suav nrog kev ntxuav (kev tshem tawm xeb, degreasing), ncaj (kho kev thauj mus los deformation), thiab siv cov primer tiv thaiv los txhim kho cov khoom siv corrosion thiab tom qab ua tiav.

2. Kos thiab Blanking

Kev kos npe yog thawj txheej txheem tsim khoom thiab cuam tshuam ncaj qha rau qhov tseeb ntawm qhov seem. Qhov loj me me yuav tsum tau muab xam raws li cov duab nthuav tawm, thiab cov kab blanking, cov kab ua haujlwm, thiab cov kab tshuaj ntsuam xyuas yuav tsum tau cim.

Blanking txoj kev muaj xws li cov neeg kho tshuab txiav (xws li tshuab shearing) thiab thermal txiav (xws li nplaim taws txiav, plasma txiav). CNC txiav tuaj yeem txhim kho qhov tseeb thiab txo cov khoom pov tseg.

3. Beveling

Txhawm rau ua kom cov vuam zoo, cov npoo ntawm daim hlau yuav tsum tau beveled. Cov txheej txheem feem ntau suav nrog kev npaj ntug lossis nplaim taws ua raws li kev ua tiav.

4. Kev tsim cov txheej txheem

Lub tog raj kheej txoj kev: Cov hlau phaj feem ntau yog dov rau hauv cov duab cylindrical siv lub phaj dov tshuab, tswj ovality thiab ntug cov ces kaum.

Head Forming: Cov txheej txheem feem ntau suav nrog:
Stamping: Haum rau huab hwm coj- tsim cov taub hau txheem;
Spinning: Haum rau ib zaug - thooj lossis loj - taub hau;
Segmented Forming: Siv rau ultra- taub hau loj, qhov twg ntu raug nias thiab tom qab ntawd welded ua ke.

Thaum tsim cov ntaub ntawv tshwj xeeb xws li zirconium, yog tias qhov kub thiab txias qis dua 500℃thiab deformation tus nqi siab dua 3%, annealing yuav tsum tau txo qis kev ntxhov siab.

5. Kev sib dhos thiab vuam

Kev sib dhos ua ntu zus yog feem ntau raws li hauv qab no: ua ntej, longitudinal seam vuam; ces, circumferential seam taub qab vuam; Thaum kawg, manholes, txuas cov kav dej, thiab lwm yam khoom siv tau teeb tsa.

Vuam txoj kev raug xaiv raws li cov khoom siv, qauv, thiab kev ua haujlwm, thiab feem ntau suav nrog:

Shielded Hlau Arc Vuam (SMAW): Kev ua haujlwm yooj yim, haum rau ntawm -kev tsim kho;

Submerged Arc Vuam (SAW): Qib siab ntawm automation, ruaj khov weld zoo, tsim nyog rau txoj haujlwm tiaj tus vuam;

Gas Shielded Vuam: Xws li TIG vuam thiab MIG / MAG vuam, tiv thaiv lub pas dej ua ke los ntawm cov pa paug, haum rau cov hlau tsis muaj steel, tsis yog{0}} hlau hlau, thiab lwm yam.

Vuam yuav tsum tau ua raws li cov txheej txheem vuam daim npav kom paub meej tias cov kev txwv (tam sim no, qhov hluav taws xob, cov txheej txheem, thiab lwm yam) raug tswj.

6. Tsis yog-Kev kuaj kev puas tsuaj

Tom qab- kev ntsuam xyuas vuam yuav tsum tau 100% tsis yog- kev sim ua kom puas tsuaj ntawm vuam. Cov txheej txheem feem ntau suav nrog kev kuaj hluav taws xob (RT), kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), thiab ntsuas kev nkag siab (PT) txhawm rau txheeb xyuas qhov teeb meem sab hauv lossis qhov chaw.

7. Kev kho cua sov

Lub hom phiaj yog txhawm rau tshem tawm qhov seem welding kev ntxhov siab thiab txhim kho microstructure thiab cov khoom. Cov txheej txheem muaj xws li kev sib txhuam tag nrho thiab kev kho cua sov hauv cheeb tsam, tshwj xeeb tshaj yog tsim rau tuab - cov thawv ntim phab ntsa lossis siab - lub zog steel ntim.

8. Kev ntsuas siab thiab kev soj ntsuam zaum kawg

Qhov no suav nrog kev ntsuas siab (hydraulic lossis pneumatic) thiab kev ntsuas huab cua kom paub tseeb tias lub thawv lub zog thiab kev sib khi ua haujlwm.

Tom qab dhau qhov kev ntsuam xyuas, qhov chaw tiv thaiv- kev kho corrosion (xws li pleev xim lossis plating) yog ua, ua raws li kev tshuaj ntsuam xyuas zaum kawg thiab cov khoom lag luam.

II. Kev Tsim Khoom Tshwj Xeeb (tseem siv tau rau cov xwm txheej tshwj xeeb)

1. Ntau- txheej qhwv Cov Thawv: Cov hlau nyias nyias yog qhov txhab lossis qhwv txheej los ntawm txheej kom tsis txhob sib sib zog nqus welds, txhim kho kev nyab xeeb. Feem ntau siv nyob rau hauv cov chiv thiab tshuaj industries.

2. Cov Thawv Ntim: Cov ntoo khaub lig tshwj xeeb- ntu steel strips yog prestressed thiab raug mob nyob ib ncig ntawm lub tog raj kheej sab hauv, tshem tawm cov welds longitudinal thiab txhim kho lub neej qaug zog.

3. Fiber-Cov Khoom Siv Cov Khoom Siv: Siv rau kev siv qis- kub lossis lub teeb yuag, cov thawv no siv cov khoom siv fiber ntau / iav fiber ntau sib xyaw, ua rau lub qhov txhab raug mob thiab kho kom ua tiav cov kev ua haujlwm siab thiab kev sib khi zoo.
