Brass castings yog siv dav hauv lub valve thiab twj tso kua mis vim qhov ua tau zoo ntawm cov khoom siv tooj dag. Ntawm RMC Foundry, peb tsuas yog tsim covtooj dag castingslos ntawm ntsuab xuab zeb casting, cob coated xuab zeb casting,peev castingthiab rau cov tooj dag loj loj, peb kuj tau txais qhov poob ua npuas ncauj casting thiab nqus casting txheej txheem. Feem ntau, cov tooj dag castings ua los ntawm cov xuab zeb casting yog cov qeb tseem ceeb hauv peb qhov chaw tsim khoom.
Ib qho tooj liab alloy nrog zinc ua lub ntsiab alloying feem ntau hu ua tooj dag. Copper-zinc binary alloy yog hu ua tooj dag zoo tib yam, thiab ternary, quaternary lossis ntau lub ntsiab lus tooj dag tsim los ntawm kev ntxiv me me ntawm lwm cov ntsiab lus ntawm lub hauv paus ntawm tooj liab-zinc alloy yog hu ua tooj dag tshwj xeeb. Casting tooj dag yog siv los ua tooj dag rau castings. Brass castings yog dav siv nyob rau hauv machinery manufacturing, valve thiab twj tso kua mis, ships, aviation, tsheb, kev tsim kho thiab lwm yam kev lag luam sectors, occupying ib tug tej yam hnyav nyob rau hauv hnyav non-ferrous hlau cov ntaub ntawv, tsim cam khwb cia tooj liab series.
Piv nrog tooj dag thiab tooj dag, cov khoom solubility ntawm zinc hauv tooj liab yog qhov loj heev. Nyob rau hauv qhov sib npaug ntawm qhov kub thiab txias, txog 37% ntawm zinc tuaj yeem yaj hauv tooj liab, thiab li 30% ntawm zinc tuaj yeem yaj hauv lub xeev li-cam khwb cia, thaum tin bronze Nyob rau hauv lub xeev as-cam khwb cia, qhov loj feem ntawm cov khoom solubility ntawm tin. nyob rau hauv tooj liab tsuas yog 5% mus rau 6%. Qhov loj feem ntawm cov khoom solubility ntawm txhuas bronze nyob rau hauv tooj liab tsuas yog 7% mus rau 8%. Yog li ntawd, zinc muaj cov tshuaj zoo ntxiv dag zog rau cov tooj liab. Nyob rau tib lub sijhawm, feem ntau cov ntsiab lus alloying tseem tuaj yeem yaj hauv cov tooj dag mus rau qhov sib txawv, Ntxiv rau nws cov khoom siv kho tshuab, kom cov tooj dag, tshwj xeeb yog qee cov tooj dag tshwj xeeb muaj cov yam ntxwv ntawm lub zog siab. Tus nqi ntawm zinc yog qis dua li ntawm txhuas, tooj liab, thiab tin, thiab nws yog nplua nuj nyob rau hauv cov peev txheej. Tus nqi ntawm zinc ntxiv rau tooj dag yog qhov loj, yog li tus nqi ntawm tooj dag yog qis dua tin bronze thiab txhuas bronze. Brass muaj qhov kub thiab txias me me, fluidity zoo, thiab yooj yim smelting.
Vim hais tias tooj dag muaj cov yam ntxwv saum toj no ntawm lub zog siab, tus nqi qis thiab kev ua haujlwm zoo casting, tooj dag muaj ntau hom, cov zis loj dua thiab daim ntawv thov dav dua li tin bronze thiab aluminium bronze hauv tooj liab alloys. Txawm li cas los xij, kev hnav tsis kam thiab corrosion kuj ntawm tooj dag tsis zoo li tooj liab, tshwj xeeb tshaj yog cov kev tiv thaiv corrosion thiab hnav tsis kam ntawm cov tooj dag zoo tib yam kuj tsawg. Tsuas yog thaum qee cov ntsiab lus hlau tau ntxiv los ua ntau yam tshwj xeeb tooj dag, nws hnav tsis kam thiab kev ua haujlwm corrosion kuj tau raug txhim kho thiab txhim kho.
Brass castings thiab bronze castings ob leeg yog tooj liab-raws li alloy castings uas yuav raug cam khwb cia los ntawm xuab zeb casting thiab peev casting txheej txheem. Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass uas muaj tooj liab thiab zinc yog hu ua tooj dag zoo tib yam. Yog tias nws yog ntau hom alloys uas muaj ntau tshaj li ob lub ntsiab lus, nws yog hu ua tooj dag tshwj xeeb. Brass yog tooj liab alloy nrog zinc ua lub ntsiab tseem ceeb. Raws li zinc cov ntsiab lus nce, lub zog thiab plasticity ntawm cov alloy nce ntau, tab sis cov khoom siv kho tshuab yuav txo qis tom qab ntau tshaj 47%, yog li zinc cov ntsiab lus ntawm tooj dag yog tsawg dua 47%. Ntxiv nrog rau zinc, cam khwb cia tooj dag feem ntau muaj cov alloying xws li silicon, manganese, txhuas, thiab txhuas.
