Casting feem ntau siv ntsug lossis kab rov tav dej-txias semi-nruam casting txoj kev. Txhawm rau txhim kho cov qauv ingot thiab nto zoo ntawm ntsug casting, electromagnetic crystallization tank, luv crystallization tank thiab kub sab saum toj casting txoj kev kuj tau tsim (saib solidification ntawm hlau). Cov txheej txheem dej-txias semi-nruab nrab casting txheej txheem qhia cov kua hlau rau hauv cov dej-txias crystallizer los ntawm kev ntxhua khaub ncaws, kom cov kua hlau txias txias los ua ib lub plhaub khov, uas yog rub tawm ntawm cov crystallizer los ntawm lub hauv paus ntawm lub tshuab casting los yog tusyees poob los ntawm nws tus kheej qhov hnyav los ua ib qho ingot. Cov txheej txheem tsis sib txawv heev nyob ntawm seb cov alloy muaj pes tsawg leeg thiab qhov loj me. Feem ntau, qhov ceev nrooj thiab qhov cua txias yuav tsum tau nce ntau npaum li qhov ua tau, thiab qhov siab ntawm crystallization tank yuav tsum raug txo kom tsawg. Qhov ntsuas kub yog feem ntau 50 txog 110 degree siab dua li cov kua dej ntawm cov hlau.
Tsis tas li ntawd, kev nruam casting thiab dov txheej txheem ntawm txhuas phaj thiab sawb kuj tau tsim. Phaj thiab sawb ntau lawm adopts tiaj yob dov, thiab cov txheej txheem yooj yim yog kub dov, txias dov, kho cua sov thiab ua tiav. Rau cov tawv aluminium alloys xws li LY12 thiab LC4 nrog cov tshuaj complex, lawv yuav tsum tau homogenized ua ntej kub dov. Kev kho mob kub yog feem ntau 10 mus rau 15 degree qis dua qhov kub ntawm eutectic ntawm lub qis melting point theem nyob rau hauv lub alloy, thiab qhov kub thiab txias yog khaws cia rau 12 mus rau 24 teev.
