Qhov saum npoo ntawm cov hlau taum - {}}}}}}}}}}}}}}} alloy} Tus kheej nyuaj particle hlau, thiab cov qauv yog xoob. Nyob rau saum npoo ntawm txhuas alloy profile, muaj ob hom hluav taws xob thiab tsis-erasure.
Lub burr (daim duab hluav taws xob) --- cov pits tsim los ntawm cov hlau loj me ntsis tom qab cov txhuam hniav txhuam, nqa tawm ntawm cov khoom siv ntws ib yam.
Ua rau txhuas tsis xws luag:
(1): cov lej sib xyaw ntawm Aluminium pas nrig, qhov ntau ntawm cov khoom siv ntawm cov khoom lag luam Magiconter), thiab cov lej Silicon ntau dua li cov qauv hluav taws xob), thiab cov hlau tshaj plaws atults yog cais tawm hauv lub Al - mg -}}}} Piv txwv, nrog kev ua haujlwm zoo nkauj, ua kom muaj zog ntau thiab tsis zoo. Feem ntau ntawm cov noob taum no tuaj yeem rub tawm (alkali ntxuav) tawm
(2): Lub hardness ntawm txoj siv ua haujlwm nyob rau hauv aluminium extusion extusion tuag yog tsis txaus, lub kaum ntse ntse heev dhau lawm, thiab txoj siv sia ntev dhau lawm.
(3): Cov Aluminium Extrusion ceev thiab extrusion kub sai dhau lawm, thiab cov pas nrig txhuas yog ntev dhau thiab cov npoo txhuas yog nias hauv.
(4): Qhov haum ntawm cov ncoo thiab ntaub qhwv thiab lub tog raj kheej tawm ntawm lub siab, thiab cov taum hlau yog feem ntau nqus nyob rau hauv lub npoo ntawm txhuas profile thiab tsis tuaj yeem wiped tawm (alkali ntxuav).
(5): Adsorption ntawm cov khib nyiab sab nraud thiab cov plua plav cua.
(6): Thaum lub sijhawm tsim khoom, tus pas nrig kub yog qhov tseeb thaum ntxov, cov noob uas tsis muaj dej nag, yog li cov noob tsw qab, yog qhov tshwj xeeb yog them rau carbide.
Ntaus:
Tus yuam sij rau kev tshem tawm cov taum hlau ntawm txhuas alloy profiles, thiab cov muaj cov teeb meem hlau ntawm cov pob zeb loj ntawm cov hlau loj ntawm cov hlau. Nyob rau hauv cov txheej txheem ntawm txhuas ntau lawm, kev sib txuam ntawm kev ua kom muaj zog, yog tias qhov txuas ntxiv ntawm cov hlau nplaum maj mam ua kom muaj zog, thiab cov khoom siv sib txawv, thiab kub qis, me ntsis hardness Alfesi Hlau hais, uas tau nias rau saum npoo ntawm qhov profile thaum dhau los ntawm kev tuag lub qhov, tsim cov taum hlau uas tsis tuaj yeem muab pov tseg ntawm tes.
Lwm qhov laj thawj pom: Changfa Aluminium 630 tons kev hloov pauv yog tsis muaj txiaj ntsig thiab yog muaj 365 degrees, thiab 390℃extrusion profile burrs ploj tom qab kho. Qhov laj thawj yog qhov kev tshem tawm ceev ntawm 6061 cov khoom siv Rim qeeb, thiab cov dej nag ntawm cov nqaj hlau Alfesi yog cov hlau sab nraud (520 degrees) thiab cuam tshuam rau saum npoo ntawm profile los ntawm thaj chaw tuag.
Tom qab shearing thiab nias, cov tuag saum npoo yog qhov tsis ncaj, thiab cov taum av yooj yim tshwm sim saum npoo ntawm qhov profile.
Yog hais tias qhov zoo ntawm tus pas tseem txom nyem heev, thiab haum ntawm cov ntaub pua av, thiab lub tog raj kheej yog cov khoom siv ntawm cov ntaub ntawv ntawm cov ntaub ntawv ntawm cov ntaub ntawv ntawm kev ua haujlwm, kev sib tw ntawm cov ntaub ntawv (daim duab hluav taws xob) ntawm qhov profile.
