Copper kab ntau lawm txheej txheem kev faib tawm thiab cov ntsiab lus piav qhia siv tshuab
1. Cov kab tooj liab
Cov khoom siv hluav taws xob tooj liab yog cov khoom siv hluav taws xob zoo tam sim no siv rau hauv cov khoom siv hluav taws xob siab thiab qis, hloov kev sib cuag, cov khoom siv faib khoom, cov tsheb thauj mus los thiab lwm yam khoom siv hluav taws xob. Nws kuj yog siv dav hauv hlau smelting, electrochemical plating, tshuaj caustic soda thiab lwm yam ultra-high tam sim no smelting los yog electrolysis. Khoom siv; tus ntoo khaub lig-section zoo yog ib lub duab plaub hla-section nrog 4 rounded ces kaum thiab cov kev cai; nws muaj mechanical zog thiab hluav taws xob conductivity zog.
2. Copper bus ntau lawm txheej txheem
Cov txheej txheem ntawm cov khoom siv tooj liab feem ntau yog muab faib ua ob txoj kev: tsoos dov thiab extrusion. Cov txheej txheem khiav yog ntev, cov txheej txheem yog complex, lub zog noj yog siab, thiab cov khoom siv yog tsawg.
A. Loj ingot kub-dov coil billet - high-precision txias dov txoj kev: Loj ingot kub dov kauj billet muaj mature technology. Kub dov tuaj yeem hloov pauv cov qauv casting, tab sis cov txheej txheem ntws tau ntev thiab cov cuab yeej siv tau loj.
B. Kab rov tav nruam nruam casting coil billet - high-precision txias dov txoj kev: Kab rov tav los yog upward nruam casting coil billet, cov txheej txheem luv luv, tsis tshua muaj nqis peev, cov khoom seem casting tom qab txias dov, yuav tsum tau nto milling, uas ua rau qis yield tus nqi.
Nruam extrusion txheej txheem: Tus tshiab nruam extrusion txheej txheem thev naus laus zis tuaj yeem ua ke qhov zoo ntawm ob txheej txheem saum toj no. Cov khoom lag luam muaj cov qauv zoo (piv rau cov qauv kub dov), cov txheej txheem luv luv, cov txiaj ntsig siab, kev nqis peev tsawg hauv cov khoom siv thiab cov nroj tsuag, thiab txo cov kev lag luam nkag. pib.
3. Qhov zoo ntawm kev nruam extrusion txheej txheem:
►Siv nruam casting thiab dov hlau pas nrig raws li raw khoom, nws yog yooj yim rau muab, tsis muaj extrusion siab residue, cov khoom siv tus nqi siab, feem ntau mus txog 95%, thiab cov uniformity ntawm cov yam ntxwv zoo.
► Nruam extrusion siv cov cua sov tsim los ntawm kev sib txhuam kom sov tsis muaj cua sov, yog li txuag lub zog.
► Tsawg cov txheej txheem, kev ua haujlwm siab ntau lawm thiab cov khoom lag luam siab.
► tuaj yeem paub cov khoom lag luam txuas ntxiv yam tsis muaj lub sijhawm.
► tuaj yeem tsim cov khoom ntev ntev
Cov txheej txheem kev ua haujlwm ib txwm tsis pub tshaj 30-50m, thaum siv txoj kev txuas ntxiv txuas ntxiv, qhov ntev feem ntau tuaj yeem nyob ntawm ntau txhiab metres mus txog kaum txhiab meters, thiab xa tuaj rau hauv daim ntawv yob kom yooj yim rau kev thauj mus los.
4. Hom kev siv ntawm kev nruam extrusion:
► Kev tsim cov kav dej tub yees
► Kev tsim cov cable TV coaxial cable sab nraud thiab kev sib txuas lus teeb liab cable sheaths
► Aluminium clad steel hlau raug tsim
► High-speed railway tooj liab alloy hu xov tooj raug
► Kev tsim cov tooj liab ca hlau thiab tooj liab tuav
►Oxygen-dawb tooj liab pas nrig ultra-wide kab nruam extrusion ntau lawm: qhov nruam extrusion dav yog txwv, feem ntau vim hais tias qhov siab tshaj plaws ntau yam yog 300mm.
Cov teeb meem tseem ceeb: yuav ua li cas sau cov pwm kab noj hniav thiab yuav ua li cas kom ntseeg tau qhov sib xws ntawm kev khiav ceev thaum lub sij hawm strip extrusion txheej txheem.
5. Kev daws teeb meem:
► Pib nrog kev tshawb fawb los ntawm cov yam ntxwv ntawm billet preheating kub, teeb tsa ntawm pwm tsis thiab xaiv tsim nyog ntawm extruder zog
►Cavity tsim
► Cov khoom siv pwm thiab cov qauv txias thiab cov khoom tom qab extrusion:
► Tom qab txuas ntxiv mus, cov khoom siv yog cov qauv recrystallized, tsis muaj cov qauv ntawm cov yas molding;
► Cov qauv zoo ib yam thiab zoo, qhov saum npoo yog du thiab tiaj tus yam tsis muaj oxidation, tsis tas yuav tsum tau kho deg, thiab tom qab dov ua tiav tuaj yeem ua ncaj qha;
►Lub hardness ntawm liab tooj liab tom qab extrusion yog hais txog HV60-70, uas yog mos; haum rau tom ntej dov ua nrog loj deformation.
6. Cov txheej txheem pom zoo txaus los tsim cov khoom siv tooj liab ultra-thin rau cov tsheb npav ducts:
Ua → extrusion → dov → annealing → kos duab
Lub dov tus nqi ntawm lub billet yog txwv, thiab lub thickness ntawm dov semi-tiav khoom yog feem ntau ntau dua 2 hli, uas yuav txaus siab los ntawm kev siv ib tug ob-yob zeb kom tsis txhob nkim lub zog.
Nruam extrusion manufacturing ntawm hollow cross-section conductive tuav (profiles): Hollow cross-section tooj liab tuav (profiles) yog dav siv nyob rau hauv electronics, hluav taws xob thiab lwm yam teb. Kev tsim khoom ntawm ntau qhov hollow heterogeneous cross-section bar yog qhov nyuaj thiab kim, thiab kev ua lag luam tsis yooj yim pom.
Kev lig kev cai - hollow ingot perforation extrusion txoj kev: tsuas tuaj yeem tsim cov duab yooj yim thiab qhov loj me (sab saum toj 50mm inch); Nws yog ib qho nyuaj rau tsim cov profiles nrog nyias phab ntsa, qhov me me, thiab ntev ntev.
Kev lig kev cai - ncab txoj kev: feem ntau tsim heterosexual kav nrog niaj hnub phab ntsa thickness. Nws yog ib qho nyuaj rau ua tiav heterogeneous kav nrog cov phab ntsa tsis sib xws thiab tsis yog kev lag luam.
Lub ntiaj teb no txoj kev tsim technology: dav kab nruam extrusion - ncaj kab extrusion, dabtsi yog khoov thawj zaug thiab ces straightening, thiab hollow kab nruam extrusion.
