1. Xaiv qhov tseeb muab tso tawm
Qhov tseeb casting kub kuj tseem yog qhov tseem ceeb los tsim cov khoom lag luam zooAluminium Pob ZebCov. Kev zam txim xws li coarse nplej thiab featherryry yog yooj yim tshwm sim thaum qhov kub siab.
Tom qab cov qoob loo nplej, cov forging kub ntawm cov kua 6063 aluminium alloy tuaj yeem nce ntxiv, feem ntau ntawm 720-740 ℃, vim tias:
(1) Ua kua txhuas ua cov nplaum tom qab cov qoob loo nplej thiab yooj yim crystallization. (2) Muaj cov kua-khoom siv ob-theem ntau dhau ntawm cov crystallization xub ntiag ntawm aluminium bar hauv forging. Qhov siab dua forging ntsuas kub muaj qhov nqaim ntau ntau cheeb tsam, uas yog qhov zoo rau kev khiav tawm ntawm cov roj tsis suav nrog lub crystallization pem hauv ntej. Ntawm chav kawm, qhov kub tsis tuaj yeem siab dhau, kev ua siab ntev dhau los yuav txo lub sijhawm muaj txiaj ntsig zoo thiab ua kom cov nplej ua loj.
2. Thaum muaj cov xwm txheej, tag nrho preheat, qhuav lub cam khwb cia xws li ntws tank thiab shunt tank kom tiv thaiv cov tshuaj tiv thaiv dej thiab kua txhuas los ua kom haum.
3. Hauv txhuas bar forging, sim kom tiv thaiv kev kub ntxhov thiab ua kua txhuas nyob rau hauv kev tiv thaiv ntawm cov khov khov rau hauv lub crystallizer crystallization.
Qhov no yog vim tias cov khoom siv agitation kua txhuas thiab kua yeeb yaj kiab ua rau txhua lub sijhawm ua yeeb yaj kiab, nyob rau tib lub sijhawm, cov yeeb yaj kiab oxide koom nrog kua txhuas.
Cov kev tshawb fawb qhia tau hais tias cov yeeb yaj kiab oxide tau muaj cov yeeb yaj kiab ua kom muaj zog, nws muaj cov yeeb yaj kiab oxide thiab ua kua txhuas
4. Lub txhuas bar aluminium lim, pom zoo yog cov khoom siv tsis sib haum, feem ntau yog cov kua roj fiber ntau, feem ntau yog siv cov phaj lim ceramic, tsis muaj teeb meem dab tsi ntawm cov qauv lim dej.
Txhawm rau kom ntseeg tau tias cov kev lim dej ua kua txhuas, kua muag tsis tuaj yeem tshem tawm cov khoom seem, yog li ntawd cov kua txhuas tshem tawm ntawm daim ntawv puab ua ntej pom kev.
