Cov txheej txheem ntawm hloov aluminium ntawv rau hauv txhuas ntawv ci cuam tshuam nrog ntau kauj ruam, suav nrog kev cas, Dov thiab Xov.
Cov txheej txheem ntawm kev ua cov paib txhuas rau hauv cov ntawv ci txhuas los ua cov theem hauv qab no:
Aluminium daim hlau thiab cov ntawv ci txhuas yog ob qho tib si sib sib zog nqus cov khoom siv txhuas cov alloys alloys. Aluminium daim hlau feem ntau dov thiab txiav los ntawm txhuas ingots. Aluminium Ntawv Nyiaj muaj qhov tuab tuab tuab. Yuav ua li cas yog nws ua tiav? Kev sib sau ntawm txhuas ntawv ci yog zoo ib yam li ntawd ntawm txhuas phaj, ob leeg uas tau txais los ntawm kev ua cov ntaub ntawv raw.
Cov khoom siv raw rau txhuas ntawv plaub tuag casting yog txhuas phaj, thiab cov txheej txheem ntawm hloov pauv txhuas mus rau hauv txhuas ntawv ci cuam tshuam nrog ntau kauj ruam, suav nrog kev cas, Dov thiab Xov.
Cov khoom siv raw:
Aluminium phaj: Cov Khoom Siv Tseem Ceeb Rau Txhuas Ntawv Nyiaj Ntau Lawm. Cov no aluminium panels feem ntau yog ua los ntawm thawj lossis rov ua dua txhuas.
Cov txheej txheem ntawm tig aluminium phaj rau cov ntawv ci txhuas
Melting: Aluminium nplooj ntawv yog melted nyob rau hauv lub cub tawg ntawm qhov kub nyob rau hauv dhau ntawm 660 ° C (1220° F).
Sib ntxaws: Thaum lub sij hawm melting txheej txheem, Lwm Cov Hlau (xws li tooj liab, tus kws dai txiv manganese, magnesium, silicon, lossis zinc) tuaj yeem muab ntxiv rau cov ntawv alloys nrog cov khoom xav tau (zog, yooj, lwm.).
Chaw ua casuming: Lub ntsej muag ci aluminium yog ces muab pov rau hauv cov pob zeb loj (tseem hu ua txhuas butter lossis dov slabs) Los ntawm cov txheej txheem hu ua Ncaj Ncees Txias Casting (Dc) chaw ua casuming. Qhov no suav nrog poling molten aluminium rau hauv pwm thiab sai sai txias nws nrog dej.
Kub Rolled Aluminium Ntawv
Preheat: Preheat cov ntawv txhuas rau ib ncig ntawm 400-500 ° C (750-930° F) kom nws ntau malleable.
Kub Rolling Zeb **: Ib qho preheated slab hla dhau ntawm ib lub rolling mills uas siv lub siab kom txo nws cov tuab. Cov txheej txheem tiav hauv ntau theem, maj mam txo cov board thickness ntawm txog 600 mm (24 ntiv tes) kom txog 2-6 mm (0.08-0.24 ntiv tes).
Cold Rolled
Cua txias: Tom qab kub dov, cia cov txhuas phaj txias.
Khaub thuas dov zeb: Cov phiaj txias txias tau ntxiv rau hauv lub khob txias colding mills ntawm chav tsev kub. Cov txheej txheem no ntxiv txo cov tuab, kom txog 0.1-0.2 mm (0.004-0.008 ntiv tes). Colding colding kuj tseem nce lub zog thiab hardness ntawm txhuas.
NTAWV NYIAJ
Thaum xub thawj Scroll:
Qib Nruab Nrab Ntawm Cov Muag Dov: Txias cov ntaub ntawv tuav txhuas cov ntawv txheeb ntxiv hauv cov ntawv tshwj xeeb Rolling Mills. Cov grinders siv kev sib xyaw ua ke ntawm kev ntsuas siab thiab tswj kom txo qis tuab rau ib puag ncig 0.005-0.02 mm (0.0002-0.0008 ntiv tes).
Kawg Scroll:
Ob Chav Txo Ob: Kom ua tiav qhov kawg ntawv ci thickness, Aluminium tuaj yeem dov los ntawm tus txheej txheem hu ua ob chav txo. Qhov no suav nrog dov ob daim ntawm daim ntawv ua ke thiab tom qab ntawd cais lawv thaum kawg. Qhov no yuav pab ua kom tiav cov ultra-nyias specifications yuav tsum muaj rau ntawv ci, feem ntau yog tsawg li 0.006 mm (0.00024 ntiv tes) lossis tsawg dua.
Ib tug anerting: Rolled txhuas yog feem ntau annealed (rhuab mus ncig 300-400 ° C) los daws kev ntxhov siab thiab txhim kho ductility.
Kev kho saum npoo:
Lubrication thiab txheej: Txhawm rau pab txhawb kev ua ntxiv thiab txhim kho kev ua haujlwm, Cov ntawv ci tuaj yeem yog lubricated lossis coated. Qhov no tuaj yeem suav nrog cov roj ntxiv, Cov kua roj vanish lossis lwm yam kev kho mob los txhim kho kev siv, corrosion tsis kam los yog adhesion rau lwm cov ntaub ntawv.
Slitting thiab txiav:
Txoj kab: Siv lub tshuab ntsuas txiav slitting txiav txiav kom cov yob ntawm txhuas ntawv ua rau nqaim. Qhov no yog ua tiav raws li cov neeg siv dav dav thiab ntev cov lus qhia.
Txiav: Koj tseem tuaj yeem txiav cov ntawv ci rau hauv cov ntaub nyias nyias yog xav tau.
Lub thawv
Kev kuaj xyuas: Tiav Aluminium Ntawv Nyiaj yog soj ntsuam kom zoo, suav nrog cov txheej txheem tuab, Nto tas thiab tsis muaj qhov tsis xws luag.
Ntim: Txhuas. Qhov no yuav suav nrog qhwv thiab thawv nrog cov ntaub ntawv tiv thaiv.
Cov txheej txheem ntawm hloov aluminium ntawv rau hauv txhuas ntawv ci cuam tshuam tau melting thiab alloying txhuas ingots, muab lawv pov rau hauv cov pob zeb, Kub thiab txias dov lub pob zeb rau hauv daim hlau, Thiab thaum kawg dov cov paib rau hauv cov ntawv puab nyias.
