Brass rods muaj kev ua haujlwm zoo thiab tuaj yeem tsim los ntawm ntau yam txheej txheem xws li casting, forging, thiab extrusion. Nyob rau tib lub sijhawm, nws muaj cov khoom siv hluav taws xob zoo heev thiab yog cov khoom siv tseem ceeb hauv kev lag luam hluav taws xob. Tsis tas li ntawd, tooj dag rods kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ua haujlwm ruaj khov hauv ntau qhov chaw.
Cov keeb kwm ntawm tooj dag pas nrig tuaj yeem taug qab mus rau lub sijhawm qub, tab sis nws tsis yog txog thaum muaj kev loj hlob ntawm kev lag luam niaj hnub uas nws tau pib siv dav. Hauv Suav teb, kev siv tooj dag tuaj yeem taug qab mus rau Jiajing lub sijhawm ntawm Ming Dynasty, thaum tooj dag pib siv los ua npib. Niaj hnub no, tooj dag pas nrig tau dhau los ua cov khoom tseem ceeb hauv kev tsim khoom.
Kev tsim cov txheej txheem ntawm tooj dag rods yuav tsum muaj ntau theem. Ua ntej, tooj liab thiab zinc nyob rau hauv cov ntaub ntawv raw yuav tsum tau smelted los ua tooj dag kua. Nyob rau hauv cov txheej txheem no, impurities nyob rau hauv lub cub tawg yuav raug muab cais los xyuas kom meej qhov zoo ntawm tus pas nrig tooj dag. Tom ntej no, cov kua tooj dag yuav tsum tau mus dhau lub impurity tshem tawm theem kom tshem tawm impurities xws li hlau thiab phosphorus. Kev tshem tawm impurity feem ntau ua tiav los ntawm kev ntxiv cov flux tsim nyog, thiab lub tshuab nqus tsev tshem tawm, pom thiab lwm txoj hauv kev kuj tuaj yeem siv. Tom qab kev tshem tawm impurity tiav, cov kua tooj dag yog nchuav rau hauv pwm los ua tus pas tooj dag ntawm qhov xav tau. Nyob rau hauv cov txheej txheem no, tsis xws li kub thiab pouring ceev yuav tsum tau tswj xyuas kom meej tias qhov luaj li cas thiab kev ua tau zoo ntawm cov khoom raws li qhov yuav tsum tau.
Tom qab tus pas nrig tooj dag tsim, nws yuav tsum tau polished nto kom tshem tawm qhov tsis xws luag thiab txhim kho qhov zoo ntawm cov khoom. Tsim nyog abrasives thiab cov txheej txheem tsis yuav tsum tau siv thaum lub sij hawm polishing txheej txheem los xyuas kom meej tias cov nto roughness ua tau raws li qhov yuav tsum tau, thaum tsis txhob over polishing thiab cov khoom poob. Thaum kawg, tus pas nrig tooj dag yuav tsum tau kuaj xyuas nruj, suav nrog qhov loj me, zoo li, nto zoo thiab lwm yam. Tsuas yog cov pas nrig tooj dag uas ua tau raws li qhov yuav tsum tau ua tau zoo tuaj yeem nkag mus rau qhov txuas ntim thiab thaum kawg xa mus rau cov neeg siv khoom.
Daim ntawv thov ntau yam ntawm tooj dag rods yog dav heev. Hauv kev tsim kho, cov pas nrig tooj dag yog siv los ua lub qhov rooj, qhov rais, cov kav dej thiab lwm yam. Nws zoo heev corrosion kuj ua rau nws tswj kev ua haujlwm ruaj khov nyob rau hauv ntau yam kev nyab xeeb. Hauv kev siv tshuab, tooj dag rods yog siv los tsim ntau yam cuab yeej precision, nkoj qhov chaw, phom plhaub, thiab lwm yam. Nyob rau hauv cov hluav taws xob teb, tooj dag rods yog dav siv nyob rau hauv lub tsim ntawm cov xov hlau, cables, cov khoom siv hluav taws xob thiab lwm yam khoom vim lawv zoo heev conductivity. Tsis tas li ntawd, tooj dag pas nrig kuj tseem siv rau hauv kev tsim cov khoom siv tshuaj, cov twj paj nruag, kho kom zoo nkauj thiab lwm yam.
Muaj ntau hom tooj dag pas nrig, ua los ntawm cov khoom sib txawv.
