1. Cov yam ntxwv txheej txheem: Feem ntautooj liab alloysmuaj loj shrinkage, uas lub solidification sequence yuav tsum tau tswj thaum lub sij hawm casting kom tsis txhob tsim ntawm shrinkage kab noj hniav.Tin bronze yog oxidized zoo nyob rau hauv cov kua hauv lub xeev, uas yuav tsum tsis txhob cuam tshuam thaum lub sij hawm pouring.Nyob rau tib lub sij hawm, lub txheej txheem pouring yuav tsum tau npaj txhij los tiv thaiv lub splashing ntawm cov hlau molten, thiaj li hais tias cov molten hlau yuav ntws smoothly.lub underside pouring system yog feem ntau ua hauj lwm nyob rau hauv ntau lawm.Tin bronze Z yog haum rau hlau pwm casting, vim hais tias cov cua txias ntawm cov pwm pwm yog ceev, uas ua rau lub solidification cheeb tsam ntawm cov hlau molten, thiab tsis yog ib qho yooj yim los muab shrinkage porosity, thiab cov txheej txheem sab hauv ntawm lub casting yog. ntom.
2. Cov smelted steel alloy ntawm cam khwb cia tooj liab alloy yog twv yuav raug hu oxidized nyob rau hauv lub xeev cov kua, thiab yog li ntawd cov tsim oxide yog yaj nyob rau hauv lub tooj liab los txiav rov qab cov neeg kho tshuab zog ntawm lub alloy.Zoo li txhuas alloys, tooj liab alloys feem ntau melted nyob rau hauv ib tug crucible cub tawg heev, thiaj li hais tias cov tooj liab kua tsis ncaj qha mus cuag roj thiab huab cua, yog li ntawm txo cov oxidation thiab poob ntawm cov hlau thiab ua kom cov hlau ntshiab.Txhawm rau kom tsis txhob oxidation ntawm tooj liab, fluxes zoo li iav thiab borax yuav tsum tau ntxiv los nkaum cov kua tooj liab thaum melting bronze.Txij li zinc nyob rau hauv tooj dag nws tus kheej yuav yog ib tug zoo deoxidizer, tsis muaj yuav tsum tau ntxiv flux thiab deoxidizer thaum melting tooj dag.
3. Kev faib tawm: Muab faib ua ob pawg: cam khwb cia tooj dag thiab cam khwb cia tooj liab;cam khwb cia tooj dag ntxiv muab faib ua tooj dag zoo tib yam thiab tshwj xeeb tooj dag;cam khwb cia bronze yog ntxiv muab faib ua tin bronze thiab tshwj xeeb bronze alloy.Copper alloy yog ib qho alloy tsim los ntawm kev ntxiv ib lossis ob peb lwm cov ntsiab lus rau cov tooj liab ntshiab vim tias cov matrix.Ntshiab tooj liab yog ntshav-liab, kuj hu ua tooj liab.Qhov ceev ntawm cov ntshiab tooj liab yog 8.96, qhov chaw khov yog 1083 ℃, thiab nws yog cov hluav taws xob zoo heev, thermal conductivity, ductility thiab corrosion kuj.
4. nws yog accustomed ua rau cov khoom siv hluav taws xob xws li generators, busbars, cables, switchgear, transformers, thiab lwm yam, ntxiv rau cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob, cov kav dej, cov khoom siv vaj huam sib luag rau hnub ci cua sov.Feem ntau siv tooj liab alloys muab faib ua peb pawg: tooj dag, tooj liab thiab cupronickel.tooj dag tej zaum yuav yog ib tug tooj liab alloy nrog zinc vim hais tias lub ntsiab additive ntsiab, uas muaj xws li ib tug zoo nkauj daj xim thiab yog sib sau ua ke raws li tooj dag.Cov tooj liab-zinc binary alloy yog hu ua tooj dag lossis tooj dag yooj yim.tooj dag nrog peb yuan muaj npe tshwj xeeb tooj dag lossis tooj dag complex.Brass alloys uas muaj tab sis 36% zinc yog tsim los ntawm cov khoom tseem ceeb thiab muaj cov khoom ua haujlwm txias.Piv txwv li, tooj dag uas muaj 30% zinc feem ntau tsis tuaj yeem ua cov mos txwv, feem ntau hu ua mos txwv casing tooj dag lossis xya-peb tooj dag.
