Qhov tuag casting qhov tsis tsim thiab cov kab noj hniav tsis puv
Ua rau:
1. Qhov kub ntawm cov pwm tuag-casting yog tsawg dhau;
2. Qhov kub ntawm cov hlau molten yog tsawg;
3. Lub siab ntawm cov xovxwm me dhau;
4. Cov hlau molten tsis txaus; Kev txhaj tshuaj nrawm dhau lawm;
5. Cov huab cua tsis tuaj yeem tso tawm.
Txoj kev hloov kho:
1- 2. Ua kom kub ntawm cov pwm tuag-casting thiab molten hlau;
3. Hloov lub tshuab siab tuag-casting;
4. Ntxiv cov hlau molten txaus, txo qhov kev txhaj tshuaj nrawm, thiab ua kom lub thickness ntawm qhov chaw noj mov.
