Muaj aluminium profiles yog ib qho kev lag luam thav duab profile tau los ntawm cua sov aluminium rods thiab extruding lawv nrog tuag. Aluminium rods yog tsim los ntawm melting thiab casting aluminium ingots, uas yog hu ua industrial aluminium profile raw cov ntaub ntawv; thiab cov ntaub ntawv raw yuav cuam tshuam ncaj qha rau kev lag luam Aluminium profile khoom kev ua tau zoo.
Kev tsim cov txhuas rods yuav tsum muaj cov kev cai siab thiab cov qauv kev lag luam los xyuas kom meej cov khoom ua tau zoo ntawm kev lag luam aluminium profiles; Cov ntsiab lus hauv qab no yuav tsum tau them nyiaj rau hauv aluminium rod melting thiab casting ntau lawm:
①: Cov ntsiab lus ntawm active impurities;
②: alloy muaj pes tsawg leeg;
③: Melt superheat kub;
④: Txoj kev hloov pauv;
⑤: Lub yaj txav mus rau lub dav hlau crystallographic;
⑥: Cua txias ceev;
⑦: Qhov ceev ntawm casting 6063 txhuas pas nrig.
