Lub crystallization yam ntxwv ntawm tooj liab alloys ntawm ntau yam compositions yog txawv, lub casting zog txawv, thiab cov txheej txheem casting yam ntxwv kuj txawv.
1. Tin bronze: Cov yam ntxwv crystallization yog qhov kub ntawm crystallization loj thiab thaj tsam loj. Nyob rau hauv cov nqe lus ntawm casting kev ua tau zoo, lub fluidity yog tsis zoo, shrinkage yog yooj yim tshwm sim, thiab nws tsis yooj yim rau oxidize. Cov yam ntxwv ntawm cov txheej txheem yog tias cov tuab-walled qhov chaw txais kev taw qhia kev ruaj ntseg (sequential solidification), thiab qhov nyuaj nyias-walled qhov chaw thiab dav dav-walled qhov chaw txais ib txhij solidification.
2. Aluminium bronze thiab aluminium brass: Cov yam ntxwv crystallization yog tias qhov kub ntawm crystallization yog me me, thiab nws yog cov yam ntxwv ntawm solidification txheej los ntawm txheej. Nyob rau hauv cov nqe lus ntawm casting kev ua tau zoo, fluidity yog zoo, concentrated shrinkage yog ib qho yooj yim rau tsim, thiab nws yog ib qho yooj yim rau oxidize. Cov txheej txheem feature yog tias aluminium bronze pouring system yog hauv qab txhaj hom, thiab aluminium brass pouring system yog qhib hom.
3. Silicon tooj dag: Cov yam ntxwv crystalline yog nruab nrab ntawm tin bronze thiab txhuas bronze. Qhov zoo tshaj plaws casting kev ua tau zoo (hauv tooj dag tshwj xeeb). Cov txheej txheem yog tus cwj pwm los ntawm cov txheej txheem sib txuas ua ke, qhov nruab nrab txhaj tshuaj tiv thaiv kab mob, thiab qhov me me ntawm qhov tsaus nti riser
