Cov yam ntxwv thiab cov txheej txheem ntawm cov raj tooj liab
Feem ntau siv cov kav dej tooj liab tuaj yeem muab faib ua hom hauv qab no:
Copper condenser tubes, crystallizer tooj liab raj, cua txias tooj liab raj, ntau yam extruded, kos (rov qab extruded) tooj liab raj, hlau-nickel tooj liab raj, tooj dag raj, tooj liab raj, cupronickel tubes, beryllium tooj liab raj, tungsten tooj liab pipes , aluminium bronze kav, tin bronze kav, imported liab tooj liab kav, thiab lwm yam.
Ntawm lawv, cov raj tooj liab tau siv dav. Txhua xyoo, 50% ntawm tooj liab yog electrolytically purified rau hauv ntshiab tooj liab thiab siv nyob rau hauv kev lag luam hluav taws xob. Cov tooj liab liab hais ntawm no yuav tsum yog cov ntshiab heev, muaj ntau tshaj 99.95% tooj liab. Ib qho me me ntawm impurities, tshwj xeeb tshaj yog phosphorus, arsenic, aluminium, thiab lwm yam, yuav txo tau qhov conductivity ntawm tooj liab.
Cov pa oxygen muaj nyob rau hauv tooj liab (ib qho me me ntawm cov pa oxygen yooj yim sib xyaw thaum lub sij hawm tooj liab smelting) muaj kev cuam tshuam zoo rau kev ua haujlwm. Tooj liab siv hauv kev lag luam hluav taws xob feem ntau yuav tsum yog tooj liab tsis muaj oxygen. Tsis tas li ntawd, impurities xws li txhuas, antimony, thiab bismuth yuav tiv thaiv cov tooj liab crystals los ntawm kev sib xyaw ua ke, ua rau thermal brittleness thiab cuam tshuam rau kev ua cov tooj liab ntshiab. Liab tooj liab yog ib hom tooj liab zoo nkauj nrog cov hluav taws xob zoo thiab cov yas, tab sis tsis muaj zog thiab tawv.
Kev sib txuas ntawm lub raj tooj liab muaj zog heev, ua rau nws siv tau ntau dua. Vim tias muaj ntau yam yeeb nkab cov ntaub ntawv nyob rau hauv kev ua lag luam, lub interface fittings feem ntau yog tooj liab kav. Txawm hais tias qee cov yeeb nkab tsis xav tau tooj liab fittings, lawv tseem yuav tsum muaj tooj liab haum ntawm qhov sib txuas nrog lub faucet.
Txawm li cas los xij, yog tias cov yeeb nkab tooj liab txuas nrog rau lwm cov kav dej, vim yog cov khoom sib txawv ntawm cov kav dej thiab cov khoom siv sib txawv, lub cev thiab cov khoom siv hluav taws xob ntawm thermal expansion thiab contraction yog txawv heev, yog li qhov ruaj khov ntawm kev sib txuas yuav ib txwm ntsib cov teeb meem ntxiv. Yog li ntawd, qhov ruaj khov ntawm kev sib txuas ntawm cov kav dej tooj liab thiab cov khoom siv tooj liab yuav ua kom zoo dua qub.
Brass tubes yog lub teeb yuag, muaj cov thermal conductivity zoo, thiab muaj lub zog qis-kub. Feem ntau siv hauv kev tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam). Nws kuj tseem siv los sib sau cov kav dej kub qis hauv cov khoom siv oxygen. Cov kav dej me me feem ntau yog siv los thauj cov kua uas muaj zog (xws li lub tshuab lubrication, roj siab tshuab, thiab lwm yam) thiab cov raj ntsuas siab siv los ua cov cuab yeej.
Brass tubes muaj zog thiab corrosion-resistant. Nws feem ntau muaj cov txiaj ntsig zoo hauv qab no: cov kav dej tooj liab yog qhov nyuaj hauv kev ntxhib los mos, tsis yooj yim rau corrosion, tiv taus qhov kub thiab txias siab, thiab tuaj yeem siv rau ntau qhov chaw uas tsis yog tooj liab. Cov raj tooj dag feem ntau muaj xws li hluav taws xob tooj dag tubes, tub yees tooj dag tubes, siab-siab resistant brass tubes, corrosion-resistant tooj dag tubes, txuas tooj dag tubes, dej kav dej, hluav taws xob cua sov tooj dag raj thiab muaj tooj dag raj. Cov kav dej tooj liab, thiab lwm yam.
Copper tubes yog lub teeb yuag, muaj cov thermal conductivity zoo, thiab muaj lub zog qis-kub. Feem ntau siv hauv kev tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam). Nws kuj tseem siv los sib sau cov kav dej kub qis hauv cov khoom siv oxygen. Cov kav dej me me feem ntau yog siv los thauj cov kua uas muaj zog (xws li lub tshuab lubrication, roj siab tshuab, thiab lwm yam) thiab cov raj ntsuas siab siv los ua cov cuab yeej.
Cov kav dej tooj liab muaj zog thiab corrosion-resistant, ua rau lawv muaj kev xaiv tsim nyog rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias kav hauv txhua lub tsev lag luam.
Cov yeeb nkab tooj liab sib xyaw ua ke ntau yam zoo: nws muaj kev ua tau zoo thiab muaj lub zog siab ntawm cov hlau zoo tib yam; Nyob rau tib lub sijhawm, nws yooj yim dua rau khoov, ntswj, tawg, thiab tawg dua li cov hlau zoo tib yam, thiab muaj qee yam te hnyav hnyav thiab cuam tshuam, yog li nws tsim nyog rau kev tsim vaj tsev. Thaum cov kav dej tooj liab hauv cov kav dej tau teeb tsa, lawv muaj kev nyab xeeb thiab txhim khu kev ntseeg siv, thiab txawm tias tsis tas yuav tsum tau saib xyuas thiab tu.
Cov kav dej tooj liab feem ntau siv rau hauv cov kav dej kais dej, cov kav dej kub thiab tub yees. Raws li kev teeb tsa cov kav dej, lawv muaj qhov zoo ntawm kev ntxhib los mos, kev tiv thaiv corrosion, kub tsis kam thiab siab ua haujlwm siab, thiab tuaj yeem siv rau ntau qhov chaw. Cov kav dej tooj liab sib xyaw ua ke qhov zoo ntawm cov kav hlau thiab cov hlau tsis yog hlau. Lawv tau siv dav hauv cov dej kub thiab dej txias thiab yog cov cuab yeej tsim nyog rau kev sib txuas cov kav dej.
Txawm hais tias muaj ntau txoj hauv kev rau cov kav dej tooj liab, lawv tuaj yeem muab faib ua ob pawg: ua haujlwm kub thiab ua haujlwm txias.
Tam sim no, txoj kev extrusion billet mov tseem yog txoj hauv kev tseem ceeb. Cov txheej txheem ntau lawm yog yaj thiab cam khwb cia electrolytic tooj liab rau hauv cov khoom puag ncig ingots, uas yog ces muab tso rau hauv lub extruder ib tug los ntawm ib tug mus rau extruded rau hauv raj billets, thiab ces txias dov los yog multi-pass linearly stretched rau ib tug disc. Nthuav lub raj uas yuav tsum tau muaj.
Copper raj extrusion yog muab faib ua qhov siab extrusion piv thiab qis extrusion piv, ob qho tib si uas muaj cov qauv ua kom zoo zoo thiab zoo nto zoo. Lub raj blanks extruded los ntawm siab extrusion ratio muaj me me specifications thiab thinner phab ntsa thickness, thiab yuav ua tiav ncaj qha rau ntawm lub nruam ncaj tshuab los yog ib tug disc stretching tshuab.
Tsawg extrusion piv extrusion tuaj yeem siv cov ingots loj rau extrude cov raj loj loj, thiab tom qab ntawd siv lub tshuab txias-dov raj rau kev ua elongation. Rau ingots nrog tib qhov loj thiab specifications, ib tug siab extrusion piv yuav tsum tau ib tug loj extrusion tonnage, thiab lub extruded yeeb nkab phab ntsa thickness kam rau ua yog loj heev.
Txij li thaum peb lub yeeb nkab dov tshuab tuaj yeem ua rau cov yeeb nkab uas tsis yog-rotating, nws tuaj yeem yooj yim dov rau hauv ib lub kauj hauv online. Nws yog tus cwj pwm los ntawm cov txheej txheem tsim khoom luv luv thiab tshem tawm cov txheej txheem reheating thiab extrusion. Nws muaj qhov zoo ntawm kev txuag hluav taws xob, txo cov khoom siv peev, thiab txo cov nqi. Qhov loj thiab hnyav tube billet tsim cov dej num zoo rau kev txhim kho cov duab ua kom zoo ntawm cov txheej txheem tom ntej.
