Thermal expansion technology tau siv dav hauv roj av,kev lag luam tshuaj, hluav taws xob fais fab thiab lwm yam kev lag luam hauv xyoo tas los no, nrog rau cov ntawv thov tseem ceeb tshaj plaws yog cov kav dej roj. Seamless steel kav ua tiav los ntawm thermal expansion technology muaj qhov zoo ntawm qhov ruaj khov, du nto, thiab tsis muaj qhov tsis xws luag. Tsis tas li ntawd, thermal expansion kuj yog siv nyob rau hauv txoj kab uas hla expansion, plhaub txo, ces kaum ua, thiab lwm yam seamless steel kav, uas txhim kho ntau lawm efficiency thiab ua kom raug.

Thermal nthuav dav seamless steel yeeb nkab yog ib hom seamless steel yeeb nkab tsim los ntawm cua sov thiab txoj kab uas hla expansion. Piv nrog rau cov kav dej txias seamless steel kav, thermally nthuav seamless steel kav muaj thinner phab ntsa thickness thiab loj txheej kab. Kev tsim cov txheej txheem thermally nthuav dav seamless steel kav muaj xws li kev sib kis perforation, cua sov, txoj kab uas hla expansion, txias thiab lwm yam. Cov txheej txheem tsim khoom no tuaj yeem ua kom ntseeg tau tias cov yeeb nkab sab hauv thiab sab nrauv yog du thiab muaj cov khoom siv zoo.
Thermal expansion ntawm steel kav yog ib qho kev siv cov yeeb nkab steel ntau lawm. Nws cov txheej txheem ntau lawm tuaj yeem muab faib ua cov kauj ruam hauv qab no: kev npaj cov khoom, preheating, thermal expansion thiab txias.
Ua ntej, npaj cov ntaub ntawv. Feem ntau siv raw cov ntaub ntawv yog seamless thiab welded steel kav feem ntau siv hauv kev lag luam roj thiab roj. Cov kav hlau steel no yuav tsum tau soj ntsuam zoo ua ntej kev tsim khoom kom paub meej tias tsim nyog. Cov yeeb nkab steel yog tom qab ntawd txiav thiab txiav kom ntseeg tau tias nws yog qhov loj thiab ntev.
Tom ntej no yog lub caij sov so. Muab cov yeeb nkab steel rau hauv lub qhov cub preheating thiab ua kom sov rau qhov kub kom haum. Lub hom phiaj ntawm preheating yog kom txo tau kev ntxhov siab thiab deformation thaum lub sij hawm tom ntej thermal expansion thiab xyuas kom meej tag nrho cov zoo thiab kev ua tau zoo ntawm cov yeeb nkab steel.
Tom qab ntawd nkag mus rau theem thermal expansion. Cov yeeb nkab steel preheated yog pub rau hauv cov yeeb nkab expander, thiab cov yeeb nkab steel yog nthuav tawm radially los ntawm lub zog ntawm cov yeeb nkab expander. Cov yeeb nkab nthuav dav feem ntau siv ob lub tapered rollers, ib qho chaw ruaj khov thiab lwm qhov tig. Cov rotating rollers thawb cov khoom nyob rau sab hauv phab ntsa ntawm cov yeeb nkab steel sab nraud, yog li nthuav cov yeeb nkab steel.
Thaum lub sij hawm thermal expansion txheej txheem, cov yeeb nkab steel raug cuam tshuam los ntawm kev quab yuam thiab kev sib txhuam ntawm cov chais, thiab qhov kub thiab txias kuj tseem yuav nce ntxiv. Qhov no tuaj yeem ua tsis tau tsuas yog kev nthuav dav ntawm cov yeeb nkab steel, tab sis kuj txhim kho cov qauv sab hauv ntawm cov yeeb nkab steel thiab txhim kho nws cov khoom siv kho tshuab. Nyob rau tib lub sijhawm, vim yog lub zog quab yuam ntawm cov yeeb nkab steel thaum lub sij hawm thermal expansion txheej txheem, ib feem ntawm cov kev ntxhov siab sab hauv tuaj yeem raug tshem tawm thiab deformation ntawm cov yeeb nkab steel tuaj yeem raug txo.
Thaum kawg, muaj qhov txias txias. Tom qab lub thermal expansion tiav lawm, cov yeeb nkab steel yuav tsum tau txias kom rov qab mus rau chav sov. Feem ntau, cov yeeb nkab steel tuaj yeem ua kom txias los ntawm kev siv lub tshuab ua kom txias, lossis cov yeeb nkab steel tuaj yeem tso cai kom txias txias. Lub hom phiaj ntawm kev ua kom txias yog txhawm rau txhim kho cov qauv ntawm cov yeeb nkab steel thiab tiv thaiv kev puas tsuaj los ntawm kev txo qhov kub ceev heev.
Txhawm rau ua kom tiav, cov txheej txheem tsim khoom ntawm cov kav dej thermally nthuav dav suav nrog plaub kauj ruam tseem ceeb: kev npaj cov khoom, preheating, thermal expansion thiab txias. Los ntawm cov txheej txheem no, thermally nthuav steel kav nrog zoo dua thiab kev ua tau zoo heev tuaj yeem tsim tau.
Raws li cov yeeb nkab ua tau zoo thiab ua tau zoo, cov txheej txheem thermal expansion ntawm seamless steel kav tau siv dav hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob thiab lwm yam lag luam. Hauv kev siv cov tswv yim, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau cov teeb meem xws li steel yeeb nkab zoo, ua haujlwm kub thiab sijhawm, tiv thaiv pwm, thiab lwm yam.
Cov khoom siv thermal expansion muaj xws li:q345 ua, 10, 20, 35, 45, 16Mn, alloy structural steel, thiab lwm yam.
