Yuav ua li cas peb tuaj yeem ua kom qhov zoo ntawm kev sib sib zog nqus ntawm kev lag luam aluminium profiles? Yam tseem ceeb yog dab tsi? Kuv ntseeg tias txhua tus yuav nkag siab tom qab nyeem cov lus qhia hauv qab no!
1. Muaj txhuas profile sib sib zog nqus ua melting rauv
Smelting furnaces kuj tseem ceeb heev. Feem ntau, square furnaces yog siv, thaum cov khoom siab tshaj yog cov cub tawg. Qee lub qhov cub tawg tuaj yeem qaij thiab nchuav molten aluminium. Muaj ib tuj, ob tons, tsib tons, kaum tons, nees nkaum-tsib tons, thiab tsib caug tons ntawm txhuas melting rauv nyob rau hauv cov nqe lus ntawm tonnage. Ib qho ntxiv yog ntxiv rau qhov cub hluav taws xob zoo li qub hauv qab aluminium melting rauv, uas yog qhov tseem ceeb rau kev npaj alloy. Nws tuaj yeem siv rau slag thiab roj tshem tawm hauv lub cub tawg, thiab tom qab ntawd cam khwb cia txhuas rods rau extrusion. Lub cub hluav taws xob dav dav, tsis hais cov roj siv, yuav tsum muaj lub qhov cub, thiab feem ntau ntawm cov pa khib nyiab thiab cov khoom seem tsim tawm thaum lub sij hawm combustion ntawm cov roj tuaj yeem tawm ntawm lub chimney. Yog tias tsis muaj qhov chimney, tag nrho cov khib nyiab thiab cov slag yog yaj rau hauv cov dej txhuas, uas ua rau txhuas rods rau extrusion. Muaj cov slag inclusions loj thiab npuas hauv, uas yog ib qho ntawm cov laj thawj rau qhov tsis zoo ntawm aluminium sib sib zog nqus ua thiab cov nqi pheej yig ntawm txhuas.
2. Cov ntsiab lus alloy
Tsuas yog cov alloys ua nrog cov qauv tsim nyog tuaj yeem ua kom zoo, txwv tsis pub yuav ua li cas rau yav tom ntej yuav tsis txhim kho qhov zoo. Qee cov tuam txhab lag luam txo qis magnesium rau qhov tsawg kawg nkaus tso cai cov ntsiab lus txhawm rau txo cov nqi. Qee tus txawm txo cov ntsiab lus ntawm magnesium tshaj qhov tsawg kawg nkaus tso cai. Yog li ntawd, cov neeg kho tshuab lub zog ntawm aluminium profiles yog tsawg heev, uas tuaj yeem yooj yim khoov nrog ob txhais tes, feem ntau hu ua mos mos li noodles. Qhov no yog ib qho laj thawj vim li cas kev sib sib zog nqus ntawm txhuas tuaj yeem pheej yig dua los ntawm ntau txhiab yuan.
Formal aluminium sib sib zog nqus ua manufacturers muaj cov qauv sab hauv thaum npaj cov khoom siv alloy, uas txhais tau hais tias txhua lub Hoobkas muaj nws tus kheej me me ntawm kev hloov pauv nyob rau hauv ntau yam ntawm ntau yam ntsiab lus. Cov kev cai piv rau txhuas, magnesium, thiab silicon yog nruj heev, thiab txhua lub Hoobkas muaj nws cov ntaub ntawv thiab khaws cia tsis pub lwm tus paub.
