Ntawm cov khoom siv steel yeeb nkab, kauv steel kav yog siv dav hauv cov dej xa dej thiab cov kav dej, kev tsim vaj tsev hauv nroog, thiab qee qhov chaw xa hluav taws xob vim lawv muaj peev xwm ua tau zoo tas li thiab dav dav adaptability. Txawm li cas los xij, cov txheej txheem tsim khoom ntawm kauv steel kav muaj ntau txoj kev sib law liag; yog tias ib qho txuas tsis raug tswj xyuas kom zoo, nws yuav muaj cov tshuaj tiv thaiv kab mob ntawm qhov zoo ntawm cov khoom tiav. Yog li ntawd, kev nkag siab txog cov ntsiab lus tseem ceeb ntawm kev tswj xyuas zoo hauv cov txheej txheem tsim khoom ntawm cov kav hlau kav yog qhov tseem ceeb rau kev xaiv cov khoom raug thiab daim ntawv thov engineering.
Tsab ntawv xov xwm no yuav muab txhais cov lus tseem ceeb ntawm kev tswj xyuas kev sib txuas uas yuav tsum tau tsom mus rau hauv cov txheej txheem tsim khoom, ua ke nrog cov txheej txheem tsim khoom tiag tiag ntawm cov kav hlau kav.
I. Raw Material Quality yog lub hauv paus ntawm Kauv Hlau Yeeb Nkab Kev Ua Haujlwm
Kauv steel kav feem ntau siv kub- dov steel strip coils ua cov khoom siv raw, thiab lawv qhov kev ruaj ntseg zoo cuam tshuam ncaj qha rau qhov sib xws ntawm cov khoom tiav.
Nyob rau theem raw khoom, peb yam yuav tsum tau tsom mus rau. Ua ntej, seb cov khoom siv ntawm cov hlau sawb ua tau raws li cov qauv tsim, nrog rau kev tawm dag zog, lub zog tensile, thiab elongation. Thib ob, kev ruaj ntseg ntawm lub thickness thiab dav ntawm cov hlau sawb; Kev sib txawv ntawm qhov dav dav yuav cuam tshuam rau lub kaum sab xis, thiab qhov tuab tsis sib xws tuaj yeem ua rau tsis sib xws weld fusion. Thib peb, qhov zoo ntawm cov hlau sawb; Qhov loj indentations, tawg, los yog inclusions yuav tau amplified rau weld defects nyob rau hauv lub tom ntej welding.
Nws tuaj yeem hais tau tias cov khoom siv tsis ruaj khov zoo yog ib qho ntawm cov teeb meem zoo tshaj plaws hauv cov kav hlau kav.
II. Qhov cuam tshuam ntawm kev tsim qhov tseeb ntawm Geometric Dimensions ntawm Cov Yeeb Nkab Lub Cev
Txoj kev tsim ntawm kauv steel kav txiav txim siab tias nws yog nyob ntawm cov khoom raug thiab kev tswj tsis tau.
Thaum lub sij hawm tsim cov txheej txheem, cov hlau sawb nkag mus rau hauv txoj kev tsim ntawm ib lub kaum sab xis helix. Yog tias lub kaum sab xis tsim tsis raug tswj xyuas kom zoo, nws yuav ncaj qha ua rau cov yeeb nkab txoj kab uas hla sib txawv, ntau ovality, los yog qhov chaw tsis ruaj khov. Nyob rau tib lub sijhawm, kev hnav khaub ncaws ntawm cov txheej txheem yuav cuam tshuam rau lub voj voog thiab lub xeev ntawm lub cev yeeb nkab.
Yog li ntawd, hauv kev tsim khoom tiag tiag, nws yog ib qho tsim nyog yuav tsum tsis tu ncua calibrate thiab tswj cov cuab yeej tsim kom ntseeg tau tias kev sib sau ua haujlwm siab thiab ruaj khov txoj hauv kev, uas yog ib qho tseem ceeb ua ntej kom ntseeg tau qhov tsim nyog geometric qhov ntev ntawm kauv steel kav.
III. Kev ruaj ntseg ntawm cov txheej txheem vuam yog qhov tseem ceeb ntawm Kev Tswj Xyuas Zoo
Vuam zoo yog ib qho ntawm cov ntsiab lus tseem ceeb tshaj plaws hauv kev tsim cov kav hlau kav.
Kauv steel kav feem ntau txais yuav cov txheej txheem submerged arc vuam rau kev sib txuas, uas muaj qhov ntev vuam ntev thiab cov kev xav tau siab rau vuam txuas ntxiv. Yog tias qhov vuam tam sim no, qhov hluav taws xob, lossis qhov vuam ceev hloov pauv ntau dhau, cov teeb meem xws li kev nkag mus tsis tiav, ntug hlawv- dhau los, lossis kev tsim vuam tsis zoo yuav tshwm sim.
Tsis tas li ntawd, qhov sib txuam ntawm cov vuam hlau thiab flux yog qhov tseem ceeb. Kev sib xyaw ua ke tsis tsim nyog ntawm cov khoom siv vuam yuav cuam tshuam rau cov khoom siv kho tshuab thiab compactness ntawm cov hlau vuam. Nyob rau hauv cov txheej txheem ntau lawm, nws yog ib qho tsim nyog los xyuas qhov tseeb ntawm qhov kev sib txuas ntawm cov khoom siv vuam los ntawm cov txheej txheem vuam tsim nyog thiab tswj xyuas qhov ruaj khov thaum lub sij hawm tsim khoom.
IV. Weld Inspection yog ibTxoj kev tseem ceeb rau kev txheeb xyuas cov teeb meem muaj peev xwm
Txij li thaum cov kauv welds txuas ntxiv mus, kev tshuaj xyuas sab nraud ib leeg tsis tuaj yeem ntsuas qhov vuam zoo, ua rau cov txheej txheem tshuaj xyuas tseem ceeb heev.
Hauv cov txheej txheem tsim khoom, kev tshuaj xyuas online ntawm welds feem ntau yog ua los txhawm rau txhawm rau pom qhov pom qhov txawv txav. Nyob rau theem khoom tiav, tsis yog -kev sim ua kom puas tsuaj yuav tsum paub meej tias cov vuam puas muaj qhov tsis xws luag xws li tawg, porosity, lossis tsis tiav fusion.
Kev tshuaj xyuas tsis yog tsuas yog siv los ua ib txoj hauv kev los txheeb xyuas cov teeb meem tab sis kuj lees paub qhov zoo ntawm cov txheej txheem tsim khoom ua ntej.
V. Qhov tseem ceeb ntawmSizing thiab Straightening txheej txheem
Tom qab vuam, kauv steel kav feem ntau pom qee qhov sib txawv ntawm qhov sib txawv los yog hauv zos khoov, uas yuav tsum tau kho los ntawm sizing thiab straightening txheej txheem.
Cov txheej txheem sizing tsuas yog tswj cov txheej kab uas hla thiab roundness, thaum straightening txhim kho lub zuag qhia tag nrho ncaj ntawm cov yeeb nkab steel. Yog tias cov kauj ruam no tsis tau ua tib zoo tswj xyuas, txawm tias cov yeeb nkab steel lub zog ua tau raws li qhov yuav tsum tau ua, nws yuav ntsib teeb meem kev sib raug zoo lossis kev sib txuas tsis zoo thaum lub sijhawm teeb tsa.
Rau engineering tej yaam num, ua tau zoo geometric dimension raug kuj yog ib feem tseem ceeb ntawm zoo.
VI. Qhov tseem ceeb ntawmKev davKev Tswj Xyuas Zoo
Los ntawm kev nkag mus rau cov khoom siv raw mus rau kev xa cov khoom tiav, kev tsim cov kav hlau kav tsis yog txiav txim siab los ntawm ib qho txheej txheem tab sis ib txoj haujlwm ua haujlwm. Txhua theem, suav nrog cov khoom siv raw, sib sau, vuam, tshuaj xyuas, thiab qhov loj me yog sib cuam tshuam; yog tias ib qho kev sib txuas tsis muaj kev tswj hwm, nws yuav cuam tshuam rau qhov kev pabcuam zaum kawg.
Yog li ntawd, cov lag luam loj hlob kauv steel yeeb nkab tsim cov lag luam feem ntau tsim kom muaj kev tswj xyuas zoo, thiab los ntawm kev tswj hwm thiab kev ntsuas thev naus laus zis, kev pheej hmoo zoo raug txheeb xyuas thiab tswj tau ntxov.
Xaus
Txawm hais tias cov txheej txheem tsim cov kav hlau kav zoo li txuas ntxiv thiab ua haujlwm tau zoo, nws txoj kev tswj xyuas tsis yooj yim. Los ntawm kev xaiv cov hlau strips mus rau kev soj ntsuam vuam, txhua qhov kev nthuav dav yog ncaj qha ntsig txog kev nyab xeeb thiab kev pabcuam lub neej ntawm cov kav hlau tiav.
Los ntawm kev nkag siab tob txog cov ntsiab lus tseem ceeb ntawm kev tswj xyuas zoo hauv cov txheej txheem tsim khoom ntawm cov kav hlau kav, nws tsis yog tsuas yog pab cov tuam txhab tsim khoom txhim kho cov khoom lag luam kom ruaj khov tab sis kuj tseem ua rau cov neeg tsim khoom lag luam thiab cov neeg yuav khoom los txiav txim siab txog kev tshawb fawb thiab kev tsim nyog hauv kev xaiv thiab kev lees paub. Qhov no yog lub tswv yim tseem ceeb ntawm engineering popularization ntawm science.
