Sab nraud txoj kab uas hla raug ntawm tuab phab ntsasquare yeeb nkabyog txiav txim los ntawm tib neeg, thiab qhov tshwm sim nyob ntawm tus neeg siv khoom.Nws nyob ntawm cov neeg siv khoom xav tau rau cov kab npoo sab nraud ntawmseamless yeeb nkab, kev ua haujlwm thiab qhov tseeb ntawmcev steelsizing khoom, thiab steel yeeb nkab sizing txheej txheem system.
Txoj kev sizing ntawm seamless yeeb nkab yog ib qho tseem ceeb rau kev txiav txim siab sab nraud txoj kab uas hla ntawm cov yeeb nkab steel.Sab nraud txoj kab uas hla raug ntawmtuab phab ntsa square kavnrog longitudinal dov sizing tuaj yeem ncav cuag li 1%, thaum lub taub sab nraud qhov tseeb ntawm cov kav dej seamless nrog cross dov sizing tuaj yeem ncav cuag 0.5%.
Kev cuam tshuam ntawm cov txheej txheem thev naus laus zis ntawm qhov tseeb ntawm txoj kab uas hla ntawm cov yeeb nkab steel feem ntau yog nyob ntawm qhov kub thiab txias ntawm cov yeeb nkab steel sizing tshuab.Lub dov kub ntawm steel yeeb nkab yog siab, thiab shrinkage ntawmtuab phab ntsa square yeeb nkabtom qab dov yog loj, uas yog feem ntau yooj yim tshaj lub sab nraud txoj kab uas hla los tsim tsis zoo deviation ntawm steel yeeb nkab;Ntawm qhov tsis sib xws, qhov qis dov kub tuaj yeem dhau qhov zoo sib txawv thiab dhau los ua cov khoom tsis raug.Yog li ntawd, cov yeeb nkab steel dov zeb yuav tsum tau hloov kho tsis tu ncua raws li qhov loj me, qib steel yeeb nkab, qhov kub thiab txias thiab cov cuab yeej hnav ntawm cov sizing tuab phab ntsa square yeeb nkab.
Nyob rau hauv tus txheej txheem ntawm kev lag luam ceev ceev, qhov kev faib ua feem ntawm tuab phab ntsa square tubes nyob rau hauv Tuam Tshoj lub steel tso zis yog nce.Vim yog siv dav ntawm cov phab ntsa tuab tuab, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau nws qhov zoo.Ntawm lawv, phab ntsa thickness sib txawv ntawm tuab phab ntsacev squareyog ib qho tseem ceeb ntsuas ntawm lawv qhov zoo, vim hais tias cov phab ntsa thickness sib txawv yuav cuam tshuam ncaj qha rau kev siv ntau ntawm cov phab ntsa tuab tuab.Nyob rau hauv kev sib tw ua lag luam hnyav zuj zus tam sim no, yog tias cov chaw tsim khoom tsim cov phab ntsa tuab tuab tsis tuaj yeem ua haujlwm tsis zoo thiab tsis tuaj yeem tsim cov khoom zoo nkauj tuab phab ntsa, nws yog ib qho inevitable uas ntau lub lag luam shares yuav poob.
Los ntawm ntau xyoo ntawm kev siv zog thiab kev xyaum tsis tu ncua, nrog rau ntau qhov kev sib pauv thiab kev ua haujlwm hloov pauv nrog qee cov tuam txhab muaj zog, ntautuab phab ntsa square tubemanufacturers tau txhim kho cov phab ntsa thickness sib txawv ntawm tuab phab ntsa square tubes.
Cia peb tham txog qee qhov teeb meem ntawm phab ntsa tuabcev squarenyob rau hauv cov txheej txheem tsim khoom tiag tiag: qhov sib txawv uas ua rau hauv cov txheej txheem tho ntawm lub piercer, cov cuab yeej tsim khoom raug thiab cov qauv, kev teeb tsa thiab kev hloov kho ntawm cov khoom siv kab, cov txheej txheem cua sov ntawm lub raj dawb paug, lub blanking ntawm lub raj dawb paug, lub hwj chim ntawm cov cuab yeej raug, thiab kev siv lub tshuab tsis siv neeg lub raj dov.
