Smelting Raw Copper
Thawj kauj ruam hauv kev tsim cov yeeb nkab tooj liab yog qhov smelting ntawm raw tooj liab. Raw tooj liab yog rhuab nyob rau hauv lub cub tawg loj mus rau ntau tshaj 1,300 degrees Celsius, qhov twg cov crude tooj liab yog hloov los ntawm cov khoom mus rau ib tug kua.
Tag nrho cov tooj liab uas tsis tau kho muaj cov cim ntawm impurities xws li npib tsib xee thiab zinc. Thaum smelted, cov impurities yog cais los ntawm cov tooj liab thiab cov ntshiab tooj liab ces pauv thiab siv los ua cov kav dej.
Kev tsim cov yeeb nkab
Cov kauj ruam tom ntej hauv kev tsim cov yeeb nkab tooj liab yog tsim. Tom qab cov tooj liab nyoos yog smelted thiab purified los ntawm kev tshem tawm impurities, nws yog pauv mus rau hauv ib tug yeeb nkab casting, uas yog ib qho tseem ceeb ntawm lub raj zoo li lub plhaub rau hauv uas molten tooj liab yog poured thiab ces sab laug kom txias.
Thaum tseem nyob rau hauv lub xeev cov kua, cov molten tooj liab yuav muab sib npaug zos thoob plaws hauv lub casting thiab, raws li nws txias, yuav harden los ua ib tug yeeb nkab ib yam nkaus thiab loj li lub casting. Thaum cov txheej txheem no tiav lawm, tus neeg ua haujlwm tshem tawm cov yeeb nkab tooj liab los ntawm qhov casting kom tau txais cov yeeb nkab tooj liab ntxhib.
Machining Copper Pipes
Cov kauj ruam kawg hauv kev tsim cov yeeb nkab tooj liab yog sizing thiab ua tiav tu. Cov yeeb nkab tooj liab yog pub los ntawm ntau cov pwm thiab txiav rau qhov ntau thiab tsawg, thiab tom ntej no, cov yeeb nkab yog ntxuav nrog dej los yog hnyav kom nws polished ntau dua.

Cov raj tooj liab yog tsim nyob rau hauv peb kauj ruam yooj yim: ua ntej, cov tooj liab crude yog smelted nyob rau hauv lub cub tawg loj. Tom ntej no, nws yog poured rau hauv ib tug casting uas muaj ib tug zoo li lub raj. Thaum muab tshem tawm los ntawm lub casting, nws yog txiav thiab ntxuav, thiab ces npaj rau kev thauj mus los thiab muag.
