- Cause of defects in oxidation of slag in aluminum castings
- Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2016-02-02 15:54 Click：
, the oxidation clamp defect of aluminum castings, in general, the oxidation clip slag is mostly distributed on the upper surface of the castings, and it is easy to occur at the corner of the cast type. Generally its fracture is gray or yellow. It is usually found in X-ray or mechanical processing and is found in alkaline washing or pickling and anodizing.
why does it produce defects in the oxidation slag of aluminum castings?
why does it produce defects in the oxidation slag of aluminum castings? the causes are nothing more than the following: (1) the furnace charge is impure, and the recycled material is used more. (2) the problem may also be in our design process, and the gating system is defective. (3) it is also possible that the slag in our alloy solution can not be cleaned up. It may also be improper operation during casting, resulting in slag inclusion. (5) it may also be that our static time is not up to date.
