1, cais raws li qhov muaj nyob hauv daim ntawv
Copper sulfide ore ntuj tooj liab ---- tooj liab ntsiab nyob rau hauv naturally generated los ntawm ntau yam ntawm daim ntawv, phaj, thaiv aggregate, tsis tshua muaj muaju. Cov ntsiab lus tooj liab yog ntau tshaj 99%, tus nqi yog ntau dua li cov tooj liab rho tawm los ntawm smelting, tab sis cov reserves tsawg heev.
Copper oxide ores ---- muaj tsawg.
Copper sulfide ore ---- muaj cov ntsiab lus tooj liab tsawg heev, feem ntau nyob ib ncig ntawm 2-3%, ntau dua 80% ntawm lub ntiaj teb tooj liab yog refined los ntawm tooj liab sulfide ore.
2, Classified raws li cov txheej txheem ntau lawm
Copper concentrate ---- smelting ua ntej xaiv cov ore nrog cov ntsiab lus tooj liab siab.
Crude tooj liab ------ cov khoom tom qab smelting ntawm tooj liab concentrates nrog ib tug tooj liab ntsiab lus ntawm 95-98%.
Ntshiab tooj liab {{0}} tooj liab nrog cov ntsiab lus ntawm 99% los yog ntau tshaj tom qab hluav taws-refining los yog electrolysis. Feem ntau hu ua ntshav tooj liab, nws muaj hluav taws xob zoo thiab thermal conductivity thiab corrosion kuj. Cov tooj liab ntshiab yog cim los ntawm tsab ntawv + T (tooj liab), xws li Tl, T2, T3, thiab lwm yam .. Cov ntsiab lus oxygen tsawg heev, tsis ntau tshaj 0. 01% ntawm cov tooj liab ntshiab hu ua tooj liab tsis muaj oxygen, nrog TU ( Tsis muaj tooj liab), xws li TU1, TU2, thiab lwm yam.
3, raws li lub ntsiab alloy muaj pes tsawg leeg kev faib tawm
Brass ----- tooj liab thiab zinc alloy, nrog zinc ua lub ntsiab alloying ntawm tooj liab alloy hu ua tooj dag. Brass nrog + H; (daj) hais xws li H80, H70, H68, thiab lwm yam.
Bronze ----- ntxiv rau tooj liab thiab zinc-nickel alloys, feem ntau yog tin bronze, aluminium bronze thiab tshwj xeeb bronze. Bronze nrog "Q" (ntsuab) hais.
Dawb tooj liab ----- tooj liab-cobalt-nickel alloy.
Copper ----- ntshiab tooj liab yog xim liab-liab hlau, feem ntau hu ua "liab tooj liab", tab sis tooj liab tsis tas yuav ntshiab tooj liab, qee zaum kuj hais txog qhov sib ntxiv ntawm me me ntawm deoxidation ntsiab lus lossis lwm cov ntsiab lus ntawm tooj liab. Raws li qhov muaj pes tsawg leeg tuaj yeem muab faib ua: tooj liab zoo tib yam (T1, T2, T3, T4), oxygen-dawb tooj liab (TU1, TU2 thiab siab purity, nqus pa tsis muaj tooj liab), deoxidized tooj liab (TUP, TUMn), ntxiv ib me me ntawm alloying ntsiab ntawm tooj liab tshwj xeeb (tooj liab arsenic, tellurium tooj liab, nyiaj tooj liab) plaub pawg.
4, raws li cov khoom lag luam kev faib tawm
Copper tube, tooj liab bar, tooj liab hlau, tooj liab phaj, tooj liab strip, tooj liab bar, tooj liab ntawv ci thiab lwm yam.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
