Cov ntaub ntawv uas siv rau tuag-casting pwm

Cov alloys siv nyob rau hauv tuag-casting yog tsuas yog unerrous alloys. Raws li rau cov hlau ferlous (hlau, hlau, thiab lwm yam), lawv tsis tshua siv tau siv vim muaj teeb meem xws li cov khoom siv pwm. Ntawm tsis-ferrous alloy tuag-castingings deingsings, aluminium alloys yog qhov feem ntau dav siv, ua raws li cov ntaub ntawv zinc. Hauv qab no yog cov lus qhia luv luv los tuag-casting cov hlau tsis-ferrous.

* Nco tseg: ① Qhov ntsuas kub nrau feem ntau ntsuas tau ntsuas los ntawm qhov kub ntawm cov hlau uas muaj cov cua sov molting.
② Qhov ntsuas kub ua kom sov ntawm zinc alloy tsis tau tshaj 450 degree kom tsis txhob muaj cov nplej coarse.
