Txhawm rau txhim kho cov dej txias ib nrab ntawm cov castings, qhov txias tso rau hauv pwm kab noj hniav thiab ntawm qhov chaw ua haujlwm yog hu ua chilled hlau. Hauv kev tsim thiab tsim cov precision castings, cov hlau txias, pouring system software thiab riser yog siv ua ke los tswj tag nrho cov txheej txheem ntawm solidification ntawm castings thiab tau txais kev tsim nyog castings.
Kev xaiv cov khoom siv hlau txias tuaj yeem tsim tau ntau yam khoom siv hlau txias. Yog li ntawd, cov ntaub ntawv hlau thiab cov ntaub ntawv hlau nrog cov thermal conductivity ntau dua thiab qhov ntsuas kub cia ntau dua li cov xuab zeb pwm raw cov ntaub ntawv tuaj yeem siv. Cov khoom siv hlau txias txias hauv kev tsim khoom thiab kev tsim khoom suav nrog npua hlau, aluminium alloy profile, high-purity graphite thiab alloy tooj liab. Npua hlau txias hlau muaj qhov ntsuas kub loj, tuaj yeem zom thiab nqus cua sov ntau dua, thiab muaj peev xwm txias txias. Ntxiv mus, npua hlau chill yog ib qho yooj yim ua thiab pheej yig tus nqi. Nws yog siv nyob rau hauv kev tsim thiab tsim ntawm aluminium alloy profiles thiab magnesium alloy precision castings, tshwj xeeb tshaj yog thaum nws muab tso rau hauv qab los yog tus Tsov tus tw kawg ntawm castings los txhim kho cov condensation sequence ntawm castings. Tsis tas li ntawd, aluminium txias hlau kuj tau siv dav.
