Tin bronze phaj casting yog tooj dag siv los tsim kev ua yeeb yam. Bronze castings yog siv dav hauv kev siv tshuab, nkoj, tsheb, kev tsim kho thiab lwm yam kev lag luam, ua rau kev ua cov tooj dag series hauv cov khoom siv hlau tsis hnyav. Feem ntau siv cov tooj dag tooj liab yog tin tooj daj, txhuas tooj liab, manganese bronze thiab txhuas bronze. Cu-Sn alloy muaj qhov ntim tsawg heev, thiab nws yog qhov yooj yim los tsim cov nruas nrhav nrog cov qhov ntev thiab cov khoom siv tes ua haujlwm nrog cov qauv meej. Casting tin tin feem ntau ntxiv cov ntsiab lus xws li zinc, txhuas, thiab phosphorus. Phosphates muaj lub siab hardness, hnav tsis kam, thiab cov khoom zoo abrasive. Hauv cov coj-resistant tin tooj liab, phosphorus cov ntsiab lus yuav ua tau kom siab npaum li 1.2%.
Zinc tuaj yeem txhim kho qhov kev npliag ntawm cov xaim thiab txo cov txheej txheem los tiv thaiv kev cais tawm ntawm tin tooj. Cov hmoov txhuas ua kom zoo dua qhov hnav tsis kam thiab kev siv tau ntawm qhov nruab nrab. Kev siv cam khwb cia tooj dag yog siv ua qhov hnav-resistant thiab corrosion-resistant qhov chaw. Phosphorus yog qhov zoo deoxidizer rau alloys tooj liab, uas tuaj yeem ua rau kom muaj qhov npliag ntawm qhov ntau ntxiv, txhim kho cov txheej txheem thiab cov khoom siv ntawm cov xeb tooj, tab sis nce qib ntawm rov qab sib cais. Qhov txwv solubility ntawm phosphorus hauv Hebei tin tooj dag yog 0.15%. Yog tias ntau dhau, nws yuav tsim lub ternary eutectic ntawm α + δ + Cu3P, nrog lub suab yaj ntawm 628 mel. Nws yog nquag ua kub brittleness thaum kub dov thiab tuaj yeem tsuas yog ua haujlwm txias.
Yog li ntawd, phosphorus cov ntsiab lus nyob hauv cov yeeb yaj kiab uas tsis sib cais yuav tsum tsis txhob ntau dua 0.5%, thiab cov phosphorus yuav tsum tsawg dua 0.25% thaum ua haujlwm kub. Phosphorus-muaj cov tin bronze yog cov ntaub ntawv zoo-ua elastic. Thaum lub sijhawm ua zaub mov, nws yog qhov yuav tsum tswj cov nplej kom zoo ua ntej txias ua haujlwm thiab kub kub annealing tom qab ua tiav. Lub zog, elastic modulus thiab qaug zog lub zog ntawm cov khoom ua tiav tau zoo yog siab dua li ntawm cov ntxhib-lis txheej txheem cov ntaub ntawv, tab sis cov khoom yas yog qis dua. Cov khoom siv ua haujlwm txias yog annealed ntawm qhov kub tsawg ntawm 200-260 ° C rau 1 mus rau 2 teev los tsim cov annealing hardening, uas tuaj yeem txhim kho ntxiv lub zog, plasticity, elastic txwv thiab elastic modulus ntawm cov khoom, thiab nce ruaj ntseg ntawm elasticity.
