1. Cov khoom lag luam zoo: cov castings muaj qhov siab qhov loj, feem ntau sib npaug rau 6 - 7, txawm nce txog 4; cov npoo ua tiav tau zoo, feem ntau sib luag rau 5 - 8; lub zog thiab tawv yog siab dua, thiab lub zog feem ntau tau ntxiv los ntawm 25 piv nrog xuab zeb casting ~ {{{5}}%, tab sis qhov elongation yog txo los ntawm txog 70%; qhov loj yog ruaj khov thiab qhov sib hloov ua tau zoo; aluminium nyias-phab ntsa ua kom yooj yim tuaj yeem tuag-cam khwb cia. Piv txwv, tsawg kawg phab ntsa tuab ntawm tam sim no zinc alloy tuag-cam khwb cia txhuas qhov chaw tuaj yeem ncav cuag 0. 3 hli; aluminium alloy castings tuaj yeem ncav cuag 0. 5 hli; qhov tsawg kawg nkaus nrum lub taub qhov siab yog 0. 7 hli; qhov tsawg kawg ntsia hlau tw pob yog 0. 7 5 hli.
2. Kev ua haujlwm siab ntau: lub tshuab ua haujlwm siab, piv txwv li, hauv tsev JⅢ 3 kab rov tav txias-cua tuag-casting aluminium tshuab tuaj yeem tuag-cam khwb cia aluminium 600-700 lub sijhawm nyob rau nruab nrab hauv yim teev, thiab me kub-chav tuag-casting txhuas tshuab tuaj yeem tuag-cam khwb cia txhuas nyob rau nruab nrab 3000-7000 zaug txhua yim teev; Kev tuag-tuag txhuas pwm muaj kev pab ntev. Thaum tuag-casting aluminium pwm thiab tuag-casting aluminium tswb alloy, qhov kev pabcuam lub neej tuaj yeem ncav cuag ntau pua txhiab txhiab lossis ntau lab lab; nws yog qhov yooj yim kom paub txog kev siv tshuab thiab kev siv tshuab.
3. Kev lag luam zoo heev: Vim muaj qhov npliag qhov tuag-cam khwb cia txhuas qhov chaw, qhov saum npoo ci thiab huv si. Feem ntau, nws tsis siv neeg kho tshuab thiab siv ncaj qha, los yog kev siv nyiaj tsawg heev, yog li nws tsis tsuas txhim kho cov khoom siv hlau, tab sis kuj txo cov khoom siv hauv kev ua tiav thiab txiv neej-teev; cov castings yog pheej yig; koj tuaj yeem siv ua ke tuag-casting aluminium mus rau lwm cov hlau lossis cov khoom siv hlau. Nws txuag tau ob lub sijhawm sib dhos thiab cov hlau
