Qhov phem tshaj impurities nyob rau hauvtooj dagyog aluminium, silicon thiab magnesium.Thaum lawv cov ntsiab lus siab tshaj 0.005%, qhov tshwm sim SiO2, MgO thiab Al2O3 oxide inclusions yuav paug cov yaj thiab txo cov kev ua tau zoo ntawm qee yam ntawm cov hlau.
Thaum smelting tin bronze, txij li thaum lub boiling point ntawm zinc yog kuj tsawg thiab muaj ib tug ntau affinity nrog oxygen, cov yaj yuav tsum deoxidized thiab ces muab tso rau hauv lub cub tawg rau melting.Chuangrui tin bronze phaj tuaj yeem ntxiv deoxidation, uas yuav pab tau kom tsis txhob muaj kev phom sij ntawm kev tsim SnO2.Cov zinc thiab phosphorus hauv cov yaj muaj cov qauv deoxidation zoo, thiab qhov tshwm sim 2ZnO·P2O5 yog yooj yim dua los cais tawm ntawm cov yaj, thiab nws muaj txiaj ntsig los txhim kho cov dej ntws ntawm cov yaj.
Siv cov nqi qhuav, lossis txawm tias preheating tus nqi ua ntej ua ntej melting, tuaj yeem txo lossis txawm tias tsis txhob siv roj los ntawm cov yaj.Raws li kev faib ua feem ntawm cov hlau tshiab thiab cov txheej txheem pov tseg kuj tseem ua rau muaj kev ruaj khov yaj zoo.Tus nqi ntawm cov txheej txheem pov tseg feem ntau yuav tsum tsis pub tshaj 20% mus rau 30%.Melts uas muaj me ntsis paug nrog impurities tuaj yeem oxidized los ntawm cua tshuab lossis los ntawm kev ntxiv cov oxidant (xws li tooj liab oxide CuO).Cov khib nyiab uas ua rau muaj kuab paug loj los ntawm qee yam impurity tuaj yeem ua kom zoo los ntawm cov kuab tshuaj lossis cov roj inert, suav nrog kev rov ua dua, txhawm rau txhim kho nws qhov zoo.
Tsim nyog noj thiab melting sequences, nrog rau smelting nrog lub hwj chim-frequency hlau-core induction rauv nrog muaj zog yaj agitation, muaj txiaj ntsim rau alleviating thiab tsis txhob sib cais.Ntxiv ib qho nyiaj npib tsib xee rau cov yaj yog qhov tsim nyog rau kev ua kom lub zog thiab crystallization ceev ntawm cov yaj, thiab muaj qee yam cuam tshuam rau kev txo qis thiab tsis txhob sib cais.Zoo sib xws additives, zirconium thiab lithium kuj raug xaiv.Ib txoj kev sib xyaw ua ke ntawm kev sib cais ntawm cov hlau lead sib cais thiab tom qab ntawd txhaj cov hmoov txhuas yaj rau hauv cov tooj liab yaj ntawm 1150-1180 ° C tuaj yeem txais yuav.Nyob rau hauv ib txwm muaj xwm txheej, smelting tin bronze uas muaj phosphorus feem ntau yog them nrog carbonaceous cov ntaub ntawv xws li charcoal los yog roj av coke yam tsis muaj hnyav.Tus neeg sawv cev npog siv thaum smelting tin bronze uas muaj zinc yuav tsum muaj xws li carbon-muaj cov ntaub ntawv xws li charcoal.Thaum nruam nruam, nws tsim nyog los tswj qhov kub thiab txias ntawm 100-150 ° C saum cov kua dej alloy.
