① kev xa khoom
Hais txog lub xeev ntawm qhov kawg ntawm cov yas deformation los yog kev kho cua sov kawg ntawm cov khoom xa tuaj. Feem ntau, kub dov lossis txias rub (dov) lub xeev lossis lub xeev tsim khoom: lub xeev kev kho cua sov rau kev xa khoom tom qab kev kho cua sov, lossis hluav taws kub (ib txwm), kev kho kom zoo, kev daws teeb meem, lub xeev annealing raws li qeb ntawm kev kho cua sov.Thaum kev txiav txim, cov xwm txheej tus me nyuam yuav tsum tau qhia hauv daim ntawv cog lus.
② yog xa los ntawm qhov hnyav tiag tiag lossis los ntawm qhov hnyav theoretical
Qhov hnyav tiag tiag-Thaum xa khoom, qhov hnyav ntawm cov khoom xa tuaj los ntawm qhov hnyav (hnyav) qhov hnyav;
Theoretical hnyav-Cov khoom hnyav yog qhov hnyav xam los ntawm lub npe loj ntawm cov hlau.Cov qauv kev suav yog raws li hauv qab no (yuav tsum tau raws li qhov hnyav theoretical, yuav tsum tau qhia hauv daim ntawv cog lus): theoretical nyhav ib meter (qhov ntom ntawm cov hlau. yog 7.85 kg/dms3) calculation formula:
Hom w = (DS) S: theoretical hnyav ntawm T ib steel yeeb nkab ib 'meter', kg / m;nominal txheej kab ntawm D-steel yeeb nkab, m: s nominal phab ntsa thickness ntawm ib steel yeeb nkab, m.
③ lav cov xwm txheej
Raws li tus txheej txheem tam sim no ntawm lub hnub teev ntawm kev tshuaj xyuas thiab xyuas kom meej qhov ua tau raws li tus qauv, hu ua cov kev lav phib xaub.Cov kev lav phib xaub kuj tau muab faib ua:
A. Cov kev lav phib xaub yooj yim (tseem hu ua qhov yuav tsum tau lav cov xwm txheej).Txawm hais tias nws tau qhia hauv daim ntawv cog lus.Tag nrho cov txheej txheem kev lag luam yuav tsum khiav tawm ntawm qhov kev tshuaj ntsuam xyuas, thiab xyuas kom meej tias qhov kev soj ntsuam tau ua tau raws li cov qauv kev cai.xws li tshuaj lom neeg muaj pes tsawg leeg, kev siv tshuab. Cov khoom, qhov sib txawv me me, qhov zoo ntawm qhov chaw thiab qhov tsis zoo, kev sim hydraulic lossis kiv cua siab lossis nthuav dav 1 1 thiab lwm yam kev sim ua haujlwm, yog qhov yuav tsum tau ua.
B. Daim ntawv cog lus lav tej yam kev mob: Dhau li ntawm qhov yooj yim lav tej yam kev mob nyob rau hauv tus txheej txheem, muaj ” kev sib tham ntawm ob tog raws li qhov yuav tsum tau ntawm tus neeg thov.Thiab nco ntsoov nws nyob rau hauv daim ntawv cog lus?The quot;los yog "thaum tus neeg yuav khoom xav tau.Nrhiav…, yuav tsum tau qhia hauv daim ntawv cog lus “;qee cov neeg siv khoom, cov kev lav phib xaub yooj yim xws li muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov sib txawv ntawm qhov loj me, thiab lwm yam) lossis cov khoom siv tshuaj xyuas ntxiv (xws li cov yeeb nkab steel ellipticity, tsis sib npaug ntawm phab ntsa thickness). Cov ntsiab lus saum toj no thiab cov kev xav tau, thaum xaj, cov khoom siv thiab cov neeg xav tau. yuav tsum sib tham, kos npe rau daim ntawv cog lus siv technology thiab qhia nws nyob rau hauv daim ntawv cog lus.Yog li ntawd, cov kev mob no kuj hu ua daim ntawv cog lus guarantee tej yam kev mob.Rau cov khoom nrog daim ntawv cog lus guarantee tej yam kev mob, tus nqi yuav tsum tau nce.
④ sau cov lus qhia lossis cov lus qhia rau
Lub "batch" nyob rau hauv tus txheej txheem yog hais txog ib chav soj ntsuam, uas yog lub soj ntsuam batch.Yog hais tias tus me nyuam chav tsev pab pawg neeg batch, hu ua tus me nyuam batch.Thaum tus me nyuam batch loj, txhua tus me nyuam batch yuav muaj xws li ob peb soj ntsuam batch: thaum tus me nyuam batch. yog me me, qhov kev tshuaj xyuas batch tuaj yeem muab faib ua ntau yam khoom xa tuaj.Cov khoom ntawm "batch" feem ntau muaj cov kev cai hauv qab no (saib cov qauv tsim nyog):
A. Txhua batch yuav tsum muaj cov kav hlau uas muaj tib lub npe (qib qib steel), tib lub cub tawg (tank) tus naj npawb lossis tib tus niam lub tshuab hluav taws xob, tib qhov kev qhia tshwj xeeb thiab tib qhov kev kho cua sov (lub sijhawm cub).
B. Rau cov khoom siv zoo carbon steel cov kav dej thiab cov kav dej, qhov sib txawv ntawm cov khoom siv hluav taws xob (cov tank) tuaj yeem muaj tib lub npe, cov lus qhia tib yam thiab tib lub sijhawm kho cua sov (lub sijhawm cub).Kev sib xyaw ntawm cov yeeb nkab steel.
C. Txhua batch ntawm welded steel yeeb nkab yuav tsum muaj cov yeeb nkab steel nrog tib qib (steel qib) thiab tib yam specification.
⑤ zoo steel thiab superior zoo hlau
Nyob rau hauv GB / T699-1999 thiab GB / T3077-1999 qauv, nws lub hom rov qab nrog "A", rau qib siab steel, txwv tsis pub zoo steel.Advanced zoo steel yog superior nyob rau hauv ib co los yog tag nrho cov nram qab no:
A. Txo cov ntsiab lus ntawm cov ntsiab lus:
B. Txo cov ntsiab lus ntawm cov khoom tsis zoo (xws li ntws, phosphorus thiab hlau):
