Cov khaub ncaws daj ntau lawm ua haujlwm yog ib qho txheej txheem kev tsim khoom, los ntawm kev npaj ntawm cov ntaub ntawv raw rau qhov kawg zoo tshuaj xyuas ntawm cov khoom. Txhua kauj ruam yog qhov tseem ceeb heev. Cov hauv qab no yog cov ncauj lus kom ntxaws ntxaws ntawm cov khaub ncaws daj ntau lawm.
Ua ntej, kev tsim cov tooj dag cov leeg pib nrog kev npaj ntawm cov ntaub ntawv raw. Cov kauj ruam no suav nrog kev xaiv siab - Zoo tooj liab alloys, uas feem ntau muaj cov khoom me me los txhim kho lawv cov khoom siv thiab corrosion tsis kam. Qhov kev xaiv ntawm tooj dag alloy nyob ntawm kev npaj siv thiab cov kev xav tau ntawm cov khoom kawg. Piv txwv li, kev thov siv lub zog muaj zog thiab cov khoom siv corrosion corrosion kuj yuav tsum tau ua feem ntawm zinc lossis lwm yam kev sib txuas.
Thaum cov cim tooj dag zog tsim nyog alloy yog xaiv, nws undergoes melting thiab tuav. This step is typically performed in a gas-protected environment to prevent oxidation of the brass during melting. Lub suab kub yaj tau teev saum toj no melting taw tes ntawm tooj dag kom ua tiav melting ua tiav ntawm cov alloy. Ib qho ntxiv, siv cov roj tiv thaiv (xws li cov roj hauv cov roj ntsha) tiv thaiv cov tooj daj los ntawm kev rov qab nrog cov pa, yog li zam dhau kev tsim cov oxides. Tom qab melting, cov kua tooj dag ua kua yog tswj kom tsis pub dhau qhov ntsuas kub tshwj xeeb los xyuas kom ntseeg tau cov kev sib luag thiab qhov ua tau zoo.
Tom ntej no, cov kab tooj daj molten tau pub rau kab rov tav tav tav nrum tshuab txuas txuas ntxiv ua pov. Nruam casting yog ib txoj kev ntawm ncaj qha casting molten hlau ua kev cuam tshuam nraim. Hauv kev tsim cov khaub ncaws tooj dag zog, txuas ntxiv ua luam yeeb ua kua rau hauv cov pwm txuas mus rau hauv cov duab zaum kawg thiab qhov ntev ntawm cov raj tooj dag. Raws li tus tooj dag ua kua txias thiab ua tau zoo, nws maj mam ua ib qho txuas txuas ntxiv raj billet. Cov kauj ruam no yuav tsum tau tswj cov khoom nrawm thiab tus nqi txias kom ntseeg tau tias qhov zoo thiab kev sib txawv ntawm tooj dag raj billet.
Tom qab nruam casting, nto ntawm cov tooj dag raj raj billet yuav muaj qhov tsis xws luag xws li cov kab nrib pleb, suav nrog, lossis saum npoo tsis xwm yeem. Yog li ntawd, cov tooj dag raj raj billet yuav tsum yauv tshem tawm cov kev tsis zoo no. Milling yog ib txoj kev tshem cov khoom siv kev hloov cov cuab yeej, uas ntse du saum npoo ntawm cov tooj dag raj billet thiab npaj nws rau kev ua cov kauj ruam.
Tom qab milling, lub tooj raj raj dawb tso tawm rau hauv peb -}} roll lub ntiaj teb dov theem. Cov kauj ruam no cuam tshuam cov tooj liab raj dawb huv siv peb cov yob kom txo qis kom txo nws lub cheeb thiab nce nws cov phab ntsa tuab. Peb - roll ntiaj chaw dov uas siv cov kev qhia hauv ib qho kev ua haujlwm hauv ib qho kev ua haujlwm, yog li kev txhim kho cov kev ua haujlwm tau zoo thiab cov khoom zoo. Thaum lub sij hawm dov, kho tswj hwm cov yob thiab ua haujlwm zoo ntawm lubrication system yog qhov tseem ceeb los ua kom muaj kev sib xws thiab qhov zoo ntawm lub raj tooj liab.
Tom qab dov, lub tooj raj tooj liab raj yog qhov txhab rau hauv coils online rau cov ncab txuas ntxiv thiab ua. Kev txhaj tshuaj hauv online yog ib txoj kev winding cov ntaub ntawv txuas ntxiv mus rau hauv coils, uas txuag tau qhov chaw thiab txhim kho ntau lawm. Thaum lub sij hawm winding, kho kom nruj ntawm winding nro thiab nrawm yog qhov yuav tsum tau los tiv thaiv deformation lossis puas rau tooj liab raj dawb paug.
Tom ntej no, lub tooj raj tooj liab raj nkag mus rau peb -} theem tandem kos cov txheej txheem. Cov kauj ruam no ntxiv txo qhov taub ntawm tooj liab raj dawb paug los ntawm ntau cov kev ua haujlwm kos duab thaum nce nws cov phab ntsa tuab thiab muaj zog. Peb - theem ua ke kos duab yog ntau}}}}} kev sib piv ntawm cov theem kom ntseeg tau tias qhov kev sib txuam thiab ruaj khov ntawm lub raj tooj liab. Thaum lub sij hawm cov txheej txheem kos duab, kho kom meej ntawm kev kos duab ceev thiab kos duab sib piv yog qhov yuav tsum tau los tiv thaiv cov kab nrib pleb lossis pob txha hauv lub raj.
Tom qab peb {-} theem sib xyaw ua ke kos duab, lub raj tooj liab nkag mus rau hauv qhov teeb tsa ua rau qhov kev ua txhaum theem. Kauj ruam no cuam tshuam ntxiv kev kos duab thiab ncaj ntawm lub tooj liab raj siv lub tshuab kaw disk. Lub disk kos tshuab siv ib khub ntawm kev sib hloov disks rau clamp raj thaum ua kom ncaj qha rau nws txoj kev ncaj qha thiab sab qhov tseeb. Thaum lub sij hawm kos duab thiab cov txheej txheem ncaj, kev kos duab thiab ncaj lub kaum ntse ntse yuav tsum tau ua kom tiav tus tooj liab zoo tshaj plaws.
Tom qab ncab thiab ncaj thiab ua kom ncaj, lub taub tooj liab txhav tsis yog - ntsuas kev ntsuas thiab ntsuas ntev. Tsis - Kev sim ua yog ib txoj kev uas siv cov txuj ci ultrasonic lossis eddy tam sim no los xyuas sab hauv thiab nto tsis xws luag nyob rau hauv lub taub tooj liab. Nws zoo tau pom tau cov kab nrib pleb, suav nrog, thiab lwm yam tsis xws luag kom ntseeg tau tias lub raj ua tau zoo thiab kev ntseeg tau. Ntev txiav cov kev txiav lub raj tooj liab rau lub sijhawm ntev raws li cov neeg siv khoom. Cov kauj ruam no yuav tsum tau tswj cov txheej txheem txiav thiab kev txiav cov neeg kom paub tseeb tias qhov ntev ntawm tooj liab raj ntsib cov qauv tsim qauv.
Tom qab tsis - Kev sim ua thiab sizing, lub taub hau tooj liab nkag rau theem ci ci. Ci annaling yog tus txheej txheem uas lub tshuab tooj liab yog rhuab rau qhov chaw tiv thaiv kub thiab kub rau qee lub sijhawm kom tshem tawm sab hauv kev ntxhov siab thiab txhim khu kev sib zog. Kev kub siab feem ntau yog li ntawm 250℃rau 350 degree, nyob ntawm alloy muaj pes tsawg leeg thiab qhov ntev ntawm lub tooj liab leeg. Thaum lub sij hawm ci ci ntsa iab, kho kom tswj tau cov cua sov thiab tus ntsuas txias yuav tsum tau ua kom tiav cov txiaj ntsig anloaling.
Tom qab annealing ua tiav, lub tooj liab tub nkag rau hauv cov khoom sib xyaw ua ke theem. Ua ke tiav yog ib txoj kev tshem tawm oxide nplai, roj stains, thiab lwm yam paug los ntawm tooj liab tub uas siv txhais tau tias. Nws tau zoo txhim kho qhov saum npoo zoo ntawm tooj liab tub, ua rau lawv smoother thiab ntau cov kev ua kom zoo nkauj. Thaum lub sij hawm ua tiav, haum txoj kev ua tiav thiab cov txheej txheem ua kom haum xeeb yuav tsum raug xaiv kom ntseeg tau tias qhov chaw zoo thiab sib xws ntawm lub tooj liab raj.
Thaum kawg, tom qab tau tshuaj ntsuam zoo, lub tooj liab leeg ya mus txog txheej thiab ntim kev kho. Kev soj ntsuam zoo muaj feem cuam tshuam nrog kev ntsuas tooj liab 'qhov ntev, cov duab, tshuaj lom neeg, thiab cov khoom siv neeg kho mob. Tsuas yog tooj liab leeg uas ua tau raws li cov qauv zoo tau txais raws li cov khoom lag luam kawg. Txheej thiab ntim tau ua los tiv thaiv cov tooj liab leeg los ntawm oxidation, corrosion, thiab lwm yam kev puas tsuaj, thaum tseem ua lawv txoj kev thauj mus los thiab khaws cia. Cov khoom txheej txheej feem ntau suav nrog cov yeeb yaj kiab yas xws li polyethylene lossis polyvinyl chloride, thaum muaj ntau dua ntawm cov hlab me.
Hauv cov ntsiab lus, cov txheej txheem ntau lawm ntawm tooj dag cov leeg yog ib txoj kev ua kom haum thiab cov txheej txheem ncaj ncees uas muaj feem xyuam nrog ntau cov kauj ruam thiab cov txheej txheem tsis sib xws. Txhua kauj ruam xav tau kev tswj hwm thiab tswj nruj ua kom ntseeg tau qhov zoo thiab kev ntseeg tau ntawm cov khoom kawg. Los ntawm kev ua tsis tu ncua kom ua tau cov txheej txheem ntau lawm thiab cov khoom siv ua tau zoo ntxiv tuaj yeem ua tau ntxiv kom tau raws li kev ua lag luam thiab cov neeg siv khoom xav tau.
Lub tuam txhab muaj pawg ntawm cov coj tooj liab ua ntau lawm cov kab hauv Suav teb, suav nrog:
German tau yog precision tooj liab raj ntau lawm kab (ib xyoos tawm ntawm 30,000 tons)
Japanese technology Tooj liab ntawv tuav kab (thinnest txog li 6μm)
Tsis Siv Neeg Siab Tooj Liab Bar Nruam Extrusion Kab
Cov Ntawv Ntse Copper thiab Sawb Fining Mill Chav Tsev
Digitalized kev tswj hwm thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm tau pom los ntawm cov khoom siv ntawm cov khoom lag luam, thiab qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01 hli.
