15 Txoj Kev Txheeb Xyuas Cov Hlau Cuav thiab Cov Hlau Tsis Zoo

Hauv cov lag luam uas kev nyab xeeb, kev ruaj khov, thiab qhov zoo yog qhov tseem ceeb, sivhlau tiag tiagtsis yog ib qho teeb meem ntawm kev nyiam xwb - nws yog qhov tsim nyog. Hmoov tsis zoo, cov khoom siv hlau cuav thiab cov khoom tsis zoo tab tom nkag mus rau hauv kev ua lag luam ntau ntxiv, tshwj xeeb tshaj yog hauv kev tsim kho, kev tsim khoom, thiab kev tsim kho vaj tse. Sivhlau cuav los yog hlau tsis zootuaj yeem ua rau muaj kev puas tsuaj loj heev, kev puas tsuaj rau cov qauv, thiab kev poob nyiaj txiag. Ua tus neeg muag khoom ntseeg siab,sakysteelntseeg hais tias yuav tsum qhia cov neeg yuav khoom thiab cov engineers txog yuav ua li cas nrhiav thiab zam cov hlau tsis zoo. Hauv tsab xov xwm no, peb teev cov npe ntawm cov hlau uas tsis zoo.15 txoj kev ua tau zootxhawm rau txheeb xyuas cov hlau cuav lossis cov hlau tsis zoo ua ntej nws lig dhau lawm.

1. Tshawb xyuas cov cim ntawm Chaw Tsim Khoom

Cov khoom siv hlau tiag tiag feem ntau muajcov cim cim meej meej, suav nrog:

• Lub npe chaw tsim khoom lossis lub logo

• Qib lossis tus qauv (piv txwv li, ASTM A36, SS304)

• Tus lej cua sov lossis tus lej pawg

Hlau cuavfeem ntau tsis muaj cov cim zoo lossis qhia txog kev txheeb xyuas tsis sib xws, tsis muaj qhov tsis zoo, lossis tsis raug.

2. Tshawb xyuas qhov tiav ntawm qhov chaw

Cov khoom siv hlau tiag tiag feem ntau muaj ibsib xws, du ntonrog rau kev tswj hwm qhov ntsuas zeb lossis cov txheej txheem.

Cov cim qhia ntawmhlau tsis zoosuav nrog:

• Cov chaw ntxhib, qhov, lossis xeb

• Cov tiav tsis sib xws

• Cov kab nrib pleb lossis cov delaminations pom tseeb

At sakysteel, tag nrho cov ntaub ntawv raug kuaj xyuas ua ntej xa khoom.

3. Xyuas kom meej qhov tseeb ntawm qhov ntev

Siv cov caliper lossis micrometers los ntsuas:

• Txoj kab uas hla

• Qhov tuab

• Ntev

Hlau cuavfeem ntau txawv ntawm qhov ntev uas tau hais, tshwj xeeb tshaj yog nyob rau hauv cov rebar pheej yig lossis cov seem ntawm cov qauv.

4. Thov Daim Ntawv Pov Thawj Xeem Khoom Siv (MTC)

Ib tus neeg muag khoom raug cai yuav tsum muab ib daim ntawv pov thawjEN 10204 3.1 lossis 3.2 MTC, piav qhia ntxiv:

• Cov tshuaj lom neeg muaj pes tsawg leeg

• Cov khoom siv kho tshuab

• Kev kho cua sov

• Cov txiaj ntsig ntawm kev sim

Tsis muaj daim ntawv pov thawj lossis cov ntaub ntawv cuav yog lub cim liab loj.

5. Ua qhov kev sim hluav taws xob

Siv lub log sib tsoo, saib cov hluav taws xob uas cov hlau tsim tawm:

• Cov hlau carbon: Cov nplaim hluav taws ntev, dawb los yog daj

• Cov hlau tsis xeb: Cov hluav taws luv luv, liab lossis txiv kab ntxwv nrog tsawg dua qhov tawg

Cov qauv hluav taws xob tsis sib xwstej zaum yuav qhia tau tias cov khoom siv tau muab cim tsis raug lossis sib xyaw tsis raug.

6. Ua Kev Ntsuas Hlau nplaum

• Cov hlau carbonyog hlau nplaum

• Cov hlau tsis xeb Austenitic (304/316)feem ntau tsis yog hlau nplaum

Yog tias cov hlau teb sib nqus tsis phim qib xav tau, nws yuav yog cuav.

7. Tshuaj xyuas qhov hnyav

Ntsuas qhov ntev ib txwm thiab muab piv rau qhov hnyav theoretical raws li qhov ceev. Tej zaum qhov kev hloov pauv yuav qhia tau tias:

• Cov ntu hollow lossis porous

• Qib khoom tsis raug

• Qhov loj me me

Cov hlau tiag tiag los ntawmsakysteelyeej ib txwm phim cov kev kam rau ua lag luam.

8. Tshawb xyuas qhov Weldability

Cov hlau cuav lossis cov hlau tsis zoo feem ntau ua haujlwm tsis zoo hauv kev vuam, ua rau:

• Cov kab nrib pleb ze ntawm thaj chaw vuam

• Kev tawg ntau dhau

• Kev nkag mus tsis sib xws

Ib qho kev sim vuam me me tuaj yeem ua rau pom qhov tsis zoo ntawm cov qauv hauv ob peb feeb xwb.

9. Nrhiav cov khoom suav nrog thiab cov khoom tsis zoo

Siv lub tshuab nqa taulub tshuab kuaj ultrasoniclos yog lub tshuab X-ray los xyuas seb puas muaj:

• Cov kab nrib pleb sab hauv

• Cov khoom siv slag

• Cov khoom siv lamination

Cov teeb meem no feem ntau tshwm sim rau cov hlau cuav lossis cov hlau rov ua dua tshiab uas tsis zoo tswj tau zoo.

10. Sim qhov Hardness

Siv ib qhoportable hardness tester, xyuas kom meej tias cov khoom siv phim qhov nyuaj uas xav tau (piv txwv li, Brinell lossis Rockwell).

Cov nqi hardness qis dhau los yog siab dhau rau qib tshaj tawm yog cov cim qhia ntawm kev hloov pauv.

11. Tshawb xyuas qhov zoo ntawm ntug

Cov khoom siv hlau tiag tiag muajcov npoo txiav huv si, tsis muaj burrlos ntawm kev txiav kom zoo los yog dov.

Cov hlau cuav lossis cov hlau rov ua dua tshiab yuav qhia tau tias:

• Cov npoo jagged

• Kev hloov xim kub

• Sab uas tawg los yog tawg lawm

12. Soj Ntsuam Kev Tiv Thaiv Kev Xeb

Yog tias koj ua haujlwm nrog cov hlau tsis xeb, ua ib qho kev ntsuaskev sim tshuaj tsuag ntsev los yog kua txiv qaubrau ntawm ib ntu me me:

• Cov hlau tsis xeb tiag tiag yuav tsum tiv taus corrosion

• Cov hlau tsis xeb cuav yuav xeb hauv ob peb teev lossis hnub

sakysteelmuab cov khoom tsis xeb uas tiv taus corrosion nrog kev taug qab tag nrho.

13. Paub meej nrog Kev Kuaj Hauv Chav Kuaj Sab Nraud

Thaum tsis paub meej, xa ib qho qauv mus rau ib tusISO daim ntawv pov thawj kuaj labrau:

• Kev tshuaj xyuas spectrochemical

• Kev ntsuam xyuas lub zog tensile

• Kev kuaj xyuas microstructure

Kev txheeb xyuas tus kheej yog qhov tseem ceeb rau cov haujlwm loj lossis muaj kev pheej hmoo siab.

14. Tshawb nrhiav lub koob npe nrov ntawm tus neeg muab khoom

Ua ntej yuav khoom:

• Tshawb xyuas cov ntawv pov thawj ntawm lub tuam txhab (ISO, SGS, BV)

• Tshawb xyuas cov kev tshuaj xyuas thiab keeb kwm kev lag luam

• Nrhiav cov ntaub ntawv tiv tauj thiab chaw nyob uas tau txheeb xyuas lawm

Cov neeg muag khoom uas tsis paub lossis tsis taug qab yog cov chaw feem ntau ntawmhlau cuav.

sakysteelyog ib lub chaw tsim khoom uas tau ntawv pov thawj nrog ntau xyoo ntawm kev paub txog kev xa tawm thoob ntiaj teb.

15. Piv Cov Nqi Lag Luam

Yog tias tus nqi muab yogqis dua tus nqi lag luam, tej zaum zoo dhau los ua qhov tseeb.

Cov neeg muag hlau cuav feem ntau ntxias cov neeg yuav khoom nrog tus nqi pheej yig tab sis xa cov khoom siv qis dua. Ib txwm piv cov nqi los ntawmntau qhov chaw ntseeg siab.
