Copper bushing centrifugal casting
Lub centrifugal casting tshuab ntawm tooj liab bushings yog ib tug npaum thiab meej casting txoj kev, uas yog dav siv nyob rau hauv lub tsim ntawm tooj liab alloy bushings siv nyob rau hauv txhua yam khoom, tsheb, mines thiab lwm yam hnyav machinery. Lub hauv paus ntsiab lus ntawm centrifugal casting yog siv lub zog centrifugal uas tsim los ntawm kev kub ceev rotating pwm kom tusyees faib cov kua hlau mus rau sab hauv phab ntsa ntawm cov pwm, yog li tsim kom muaj kev ua haujlwm siab thiab ua haujlwm zoo.
Lub hauv paus ntsiab lus ntawm centrifugal casting tshuab
Centrifugal casting yog nchuav cov kua hlau molten rau hauv cov pwm rotating, thawb cov kua hlau mus rau phab ntsa pwm los ntawm kev quab yuam centrifugal, thiab thaum kawg tsim cov khoom casting. Thaum lub sij hawm casting txheej txheem, vim qhov kev txiav txim ntawm centrifugal quab yuam, qhov ceev ntawm lub puab thiab txheej txheej ntawm lub casting yog txawv. Cov txheej txheej sab nraud los ze dua rau cov pwm ntsa, uas feem ntau yog cov txheej txheem sib xyaw thiab cov txheej txheem tuab, uas yog qhov tsim nyog rau kev ua cov khoom siv nrog cov khoom tshwj xeeb lub cev.
Centrifugal casting txheej txheem ntawm tooj liab bushings
Copper bushings feem ntau yog ua los ntawm cov khoom siv tooj liab. Cov txheej txheem centrifugal casting feem ntau suav nrog cov kauj ruam hauv qab no:
1. Pwm npaj Cov pwm feem ntau yog ua los ntawm cov ntaub ntawv muaj zog refractory, uas tuaj yeem tiv taus qhov kub thiab txias thiab ruaj khov thaum tig. Lub puab phab ntsa ntawm cov pwm tuaj yeem tsim los ntawm cov duab ntawm lub bushing.
2. Hlau melting Cov tooj liab alloy yog rhuab mus rau lub xeev molten, feem ntau nyob rau hauv ib tug high-kub rauv, thiab melting kub yog feem ntau ntawm 1050 ° C thiab 1150 ° C.
3. Ncuav cov molten hlau Cov hlau molten yog nchuav rau hauv cov pwm rotating los ntawm lub pas dej molten. Kev sib hloov ceev ntawm cov pwm feem ntau yog tswj ntawm kaum mus rau pua pua ntawm kev hloov pauv ib feeb, thiab kev sib hloov ceev ncaj qha cuam tshuam rau qhov zoo thiab cov qauv ntawm cov casting.
4. Txias thiab solidification Cov hlau molten solidifies nyob rau hauv pwm vim txias. Vim yog qhov kev txiav txim ntawm lub zog centrifugal, cov hlau molten yog sib npaug sib npaug, tsim cov phab ntsa sab nrauv siab, thaum lub phab ntsa sab hauv yog xoob.
5. Demolding thiab tshuaj xyuas Tom qab lub casting txias lawm, cov pwm nres rotating, demolding thiab tsim nyog tshuaj xyuas yog nqa tawm los xyuas kom meej tias cov tooj liab bushing ua tau raws li qhov loj thiab zoo yuav tsum tau.
Qhov zoo ntawm centrifugal casting tooj liab bushings
High ceev thiab siab zog: centrifugal casting tuaj yeem ua rau txheej txheej ntawm cov casting ntom los ntawm centrifugal quab yuam, thiab muaj cov khoom siv tshuab siab.
1. Tsawg dua qhov tsis xws luag: centrifugal casting txo qhov tsim ntawm qhov tsis xws luag xws li pores thiab inclusions, thiab txhim kho qhov zoo ntawm castings.
2. Zoo hnav tsis kam: Copper alloy bushings feem ntau yog siv los tiv thaiv kev sib txhuam ntau dua. Centrifugal casting tshuab ua rau saum npoo hardness ntawm castings siab dua thiab hnav kuj zoo dua.
3. High molding precision: Centrifugally cam khwb cia tooj liab bushings tuaj yeem tswj qhov loj thiab cov duab, txo cov kev ua haujlwm tom qab.
Cov ntaub ntawv siv tau
Copper alloy cov ntaub ntawv feem ntau siv rau centrifugal casting muaj xws li:
Cam khwb cia tooj liab (xws li tooj liab-tin alloy, tooj liab-lead alloy)
Cam khwb cia tooj liab (xws li tooj liab, txhuas bronze)
Aluminium bronze, cov hlau no muaj kev tiv thaiv corrosion zoo thiab hnav tsis kam, haum rau siv los ua cov ntaub ntawv bushing.
Cov chaw thov
Lub centrifugal casting tshuab ntawm tooj liab bushings feem ntau yog siv los tsim cov bushings, bearings, sliders thiab lwm yam, thiab yog dav siv nyob rau hauv:
Cov cuab yeej siv tshuab: xws li cov kabmob bushings hauv cov khoom siv sib kis.
Automotive kev lag luam: Bushings siv rau tsheb cav, gearboxes thiab lwm yam.
Cov cuab yeej siv mining: Siv rau qhov chaw uas yuav tsum tau hnav tsis kam hauv cov tshuab mining.
Kev cuam tshuam ntawm cov txheej txheem parameter
Kev sib hloov ceev: Kev sib hloov ceev txiav txim siab qhov sib xws ntawm cov kua hlau faib thiab qhov ntom ntawm cov casting. Siab dhau los yog qis dhau yuav cuam tshuam rau qhov zoo ntawm casting.
Hlau ua kua kub: Tsis tshua muaj hlau ua kua kub yuav ua rau cov kua dej tsis zoo, thaum kub kub heev yuav ua rau oxidation thiab lwm yam teeb meem.
Txias ceev: Qhov txias ceev cuam tshuam rau microstructure ntawm lub casting. Kev nrawm dhau los yog qeeb dhau yuav cuam tshuam rau kev ua haujlwm ntawm tooj liab bushing.
Nyob rau hauv luv luv, lub centrifugal casting tshuab ntawm tooj liab bushing yog ib tug zoo heev txheej txheem. Nws tuaj yeem tsim tooj liab alloy bushings nrog cov cuab yeej zoo heev, qhov tseeb qhov tseeb thiab du nto. Nws yog ib txoj hauv kev tsim khoom zoo tshaj plaws rau ntau qhov chaw ua haujlwm siab.
