Tin bronze phajcasting yog bronze yuav tsis tsim castings.Bronze castings yog dav siv nyob rau hauv machinery manufacturing, ships, tsheb, kev tsim kho thiab lwm yam sectors, tsim cam khwb cia tooj liab series nyob rau hauv hnyav non-ferrous hlau cov ntaub ntawv.Feem ntau siv cam khwb cia bronzes yog tin bronze phaj, txhuas bronze, Muntz hlau thiab txhuas bronze.Tus nqi shrinkage ntawm Cu-Sn alloy yog qhov tsawg heev (tus nqi qis qis yog 1.45% mus rau 1.5%), thiab nws yooj yim los muab cov txheej txheem castings thiab cov khoom siv tes ua nrog cov qauv meej uas xav tau qhov ntev.Nyob rau hauv hnav-resistant tin bronze, cov ntsiab lus phosphorus feem ntau siab li 1.2%.Zinc tuaj yeem txhim kho qhov fluidity ntawm cov hlau thiab txo qhov thim rov qab kev sib cais ntawm tin bronze.Lead ho txhim kho qhov hnav thiab tsim kua muag thiab machinability ntawm alloy.Cam khwb cia tin bronze yog ua hauj lwm raws li hnav thiab corrosion resistant qhov chaw.Tin Phosphor Bronze: Phosphorus tuaj yeem yog ib qho zoo deoxidizer rau tooj liab alloys, uas yuav ua rau kom cov fluidity ntawm cov hlau, txhim kho cov thev naus laus zis thiab cov cuab yeej cuab tam ntawm tin bronze, tab sis nce qib ntawm kev sib cais rov qab.Qhov txwv tsis pub solubility ntawm phosphorus hauv Hebei tin bronze yog 0.15%, yog tias muaj ntau dhau ntawm, nws yuav tsim α + δ + Cu3P ternary eutectic, qhov chaw khov yog 628 ℃, nws yooj yim los muab kub brittleness thaum kub dov, yog li nws tsuas yog ua haujlwm txias.Yog li ntawd, phosphorus cov ntsiab lus nyob rau hauv deformed tin bronze yuav tsum tsis txhob ntau tshaj 0.5%, thiab yog li ntawd cov phosphorus yuav tsum tab sis 0.25% thaum lub sij hawm ua hauj lwm kub.Phosphorus-muaj tin bronze tuaj yeem yog cov khoom siv elastic zoo.Thaum lub sij hawm ua, nws yog ib qho tsim nyog los tswj cov qoob loo ua ntej ua haujlwm txias thiab txias annealing tom qab ua.Lub zog, modulus ntawm elasticity thiab qaug zog lub zog ntawm cov khoom zoo-grained yog tshaj li cov khoom coarse-grained, tab sis cov yas qis dua.Cov ntaub ntawv txias ua haujlwm yog annealed ntawm kas fes kub ntawm 200-260 ℃ rau 1-2 teev, ua rau cov nyhuv annealing thiab hardening, uas yuav ntxiv dag zog rau lub zog, plasticity, elastic txwv thiab modulus ntawm elasticity ntawm cov khoom, thiab ua kom lub suab ntawm elasticity.Tin-zinc bronze: ib tug loj npaum li cas ntawm zinc yog yaj nyob rau hauv tooj liab-tin alloy, thiab yog li ntawd ntxiv zinc nyob rau hauv deformed tin bronze feem ntau yog tsawg tshaj li 4%.Zinc tuaj yeem txhim kho qhov fluidity ntawm cov hlau, nqaim lub crystallization kub ntau, thiab txo qhov kev sib cais rov qab.
