Thermal expansion yog lub siab ua technology uas siv plaub-kem hydraulic xovxwm los yog ib tug neeg kho tshuab txoj kev los kho qhov ceev ntawm lub puab phab ntsa ntawm seamless steel yeeb nkab kom cov seamless steel yeeb nkab yog nthuav raws li axis. Txoj kev siv tshuab yog yooj yim dua thiab ua tau zoo dua li plaub-kem hydraulic txoj kev. Siab, nyob rau hauv lub neej niaj hnub no, ntau qhov loj-inch ncaj seam welded yeeb nkab expansion ntau lawm txheej txheem tau txais yuav. Txoj kev khiav yog:
Cov cuab yeej siv txoj kab uas hla nthuav dav siv qhov sib cais arc-shaped block ntawm qhov kawg ntawm txoj kab uas hla expander kom nthuav dav hauv cov kev taw qhia radial, yog li cov khoom siv yeeb nkab tau dhau los ua qhov ntev ntev ntawm cov yas deformation raws qhov ntev ntawm servo lub cev muaj zog, uas tau muab faib ua tsib. theem.
Nyob rau hauv lub rounding theem, lub sector blocks yog qhib kom txog thaum tag nrho cov sector blocks nyob rau hauv kev sib cuag nrog lub puab phab ntsa ntawm seamless steel yeeb nkab. Nyob rau lub sijhawm no, lub vojvoog ntawm txhua qhov taw tes hauv cov duab plaub hauv cov yeeb nkab steel seamless nyob rau hauv cov kauj ruam ntau yog yuav luag tib yam, thiab seamless steel yeeb nkab yog puag ncig. puag ncig.
Dab tsi yog lub zog tensile ntawm ncaj seam welded yeeb nkab?
Lub zog ntawm ncaj seam welded kav yog feem ntau siab tshaj qhov ncaj seam steel kav. Welded kav nrog cov yeeb nkab loj dua tuaj yeem tsim los ntawm nqaim forging billets, los yog welded kav nrog txawv cov yeeb nkab diameters tuaj yeem tsim los ntawm cov hlau ntawm tib qhov dav. Txawm li cas los xij, piv nrog cov kab ncaj nraim welded kav ntawm tib qhov ntev, qhov ntev vuam yog nce los ntawm 30 mus rau 100%, thiab cov khoom ceev yog tsawg heev. Yog li ntawd, feem ntau ntawm cov kav hlau loj loj siv cov hlua khi ncaj nraim, thaum feem ntau ntawm cov kav hlau loj loj siv cov hlua khi ncaj nraim.
Lub tswv yim tseem ceeb ntawm txoj hlua ncaj nraim welded yeeb nkab, ncaj seam siab zaus welded steel yeeb nkab, thiab lub tshuab vuam ntau zaus: tom qab kub dov steel phaj yog tsim los ntawm lub tshuab tsim, qhov surge tam sim no thiab qhov sib thooj ntawm cov high zaus tam sim no yog siv los ua cua sov. thiab yaj cov ntug ntawm cov khoom siv yeeb nkab. Seamless steel kav yog tsim los ntawm lub siab vuam nyob rau hauv qhov kev txiav txim ntawm rollers. Cov yam ntxwv ntawm high-frequency welded steel kav: Cov burrs nyob rau hauv cov hluav taws xob vuam daim ntawv ntawm ERW welded kav yog tag nrho cov shaved tawm mus rau raw khoom.
Cov qauv duab nraaj yog siab-precision, siab parallelism, uniform thickness, thiab cov alloy muaj pes tsawg leeg yog uniform tom qab vuam tom qab kev kho cua sov. Nws muaj tib lub siab crush kuj zoo li seamless steel kav. Lub kaum sab xis ntawm txoj hlua ncaj nraim welded yeeb nkab vuam yog feem ntau 50-75 degrees. , yog li qhov kev ntxhov siab uas tsim los ntawm kev sib koom ua ke ntawm qhov ncaj seam weld yog 60-85% ntawm cov kev ntxhov siab ntawm cov yeeb nkab ncaj seam welded. Nyob rau hauv tib lub siab, lub thickness ntawm ncaj seam welded kav nrog tib txoj kab uas hla yuav txo tau piv nrog ncaj seam steel kav.
