| Abstract: | The causes of common defects such as sticky sand, porosity, collapse boxes, wall thickening and slag when the Al-Si alloy casting with vacuum sealed molding are analyzed. And the corresponding control measures are proposed. By rationally choosing the modeling materials, strictly controlling vacuum degree, vibration time and melting casting technological parameters, strengthening the mold venting, safely keeping the raw materials, selecting the appropriate gating system, these defects can be effectively prev... |
