Thermal expansion yog ib txoj kev ua rau cov kav hlau. Nws yog los ua cov kav hlau me me rau hauv cov kav hlau loj uas muaj qhov ntom ntom tab sis muaj zog shrinkage. Tom qab cov kav dej tau txais cov thev naus laus zis thev naus laus zis thev naus laus zis, cov kev ntxhov siab sab hauv (sab hauv) tuaj yeem tshem tawm tau zoo, thiab cov khoom siv kho tshuab ntawm cov yeeb nkab steel tau txhim kho los npaj rau cov txheej txheem tom ntej.
1. Qhov kev ntxhov siab seem yog dab tsi? Qhov kev ntxhov siab uas tseem nyob hauv cov hlau tom qab lub zog sab nraud raug tshem tawm yog hu ua residual stress lossis kev ntxhov siab sab hauv. Residual stress yog vim tsis zoo ib yam deformation thiab non-uniform ntim hloov ntawm cov hlau.
2. Dab tsi yog qhov teeb meem ntawm kev ntxhov siab uas seem?
Residual stress muaj ib qho tseem ceeb heev cuam tshuam rau cov duab, qhov loj thiab kev ua tau zoo ntawm workpiece. Thaum nws dhau lub zog ntawm cov khoom siv, nws yuav ua rau deformation ntawm lub workpiece. Thaum nws tshaj qhov txwv lub zog ntawm cov khoom, nws yuav ua rau tawg thiab ib feem me me los yog cov duab hloov ntawm lub workpiece. , zoo heev txo lub neej kev pab cuam ntawm lub workpiece.
Cov yeeb nkab steel txais cov thev naus laus zis thev naus laus zis los txhim kho cov khoom siv hluav taws xob ntawm cov yeeb nkab steel thiab tshem tawm cov kev ntxhov siab sab hauv (kev ntxhov siab sab hauv) zoo!
Txoj kab uas hla kev nthuav dav yog nruab nrog cov khoom siv hluav taws xob nruab nrab ntawm cov cua sov kom sov tsuas yog qhov deformed ntawm cov khoom siv raw, thiab cov cua sov yog ceev, zoo ib yam thiab tswj tau, txuag lub zog. Lub tapered puab pwm mandrel tuaj yeem hloov tau sai sai kom paub cov khoom siv tau yooj yim thiab hloov tau cov khoom tiav tiav.Ntxiv mus, nws tuaj yeem rhuav tshem cov qauv forging ntawm cov yeeb nkab steel, ua ntej lub deformation ntawm ib tug uniform ceev thiab tswj qhov kub thiab txias, refine cov nplej. lub tshav kub-expanded steel yeeb nkab, thiab tshem tawm qhov tsis xws luag ntawm microstructure, thiaj li hais tias cov qauv ntawm lub tshav kub-expanded steel yeeb nkab yog ntom thiab cov neeg kho tshuab zog zoo dua. Qhov kev txhim kho no feem ntau yog tshwm sim nyob rau hauv cov kev taw qhia dov, yog li ntawd cov thermal expansion steel yeeb nkab tsis yog isotropic rau qee yam; cov npuas, tawg thiab looseness tsim thaum lub sij hawm pouring kuj yuav welded nyob rau hauv qhov kev txiav txim ntawm kub kub thiab parallel siab. Tom qab cov yeeb nkab steel yog thermally nthuav dav, qhov hardness ntawm cov yeeb nkab steel kuj tuaj yeem txo thiab cov yas tuaj yeem txhim kho kom yooj yim rau kev txiav tom qab lossis txias deformation. Thaum kawg, qhov kev ntxhov siab sab hauv ntawm cov yeeb nkab steel raug tshem tawm zoo heev los tiv thaiv deformation los yog tawg! Ob-kauj ruam laub-hom yeeb nkab expanding tshuab siv nyob rau hauv thermal expansion steel yeeb nkab integrates cone tuag txoj kab uas hla expanding tshuab, digital intermediate zaus induction cua sov tshuab, thiab hydraulic technology nyob rau hauv ib lub tshuab. Nrog nws cov cuab yeej tsim nyog, kev siv hluav taws xob tsawg, kev tsim kho qis, cov khoom lag luam zoo heev, ntau yam khoom siv raw thiab cov khoom siv tshwj xeeb, hloov tau yooj yim thiab cov khoom siv qis qis, hloov cov tsoos rub-hom txoj kab uas hla expansion tshuab hauv cov yeeb nkab steel. kev lag luam, thiab tam sim no tau siv dav.
