- Causes and measures of oxidizing slag inclusion in aluminum castings
- Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2016-01-15 16:04 Click：
aluminum castings are indispensable products in automobile, space and industry, especially in the automotive industry, more important parts. Hangzhou Hongcheng Pml Precision Mechanism Ltd, as an aluminum casting manufacturer in Hangzhou, provides aluminum sand casting, foundry, low pressure die casting and high strength casting.
aluminum casting production process will produce some problems, and finally lead to defects of the finished product. Today, the macro will share with you the aluminum castings to oxidize the garden garden and prevention measures.
oxidized slag is mostly distributed on the upper surface of the casting, at the corner where the mold is not ventilated. The fracture is mostly gray or yellow. It can be found in alkali washing, pickling or anodizing by means of X light or mechanical processing.
oxidized slag is mostly distributed on the upper surface of the casting, at the corner where the mold is not ventilated. The fracture is mostly gray or yellow. It can be found in alkali washing, pickling or anodizing by means of X light or mechanical processing. the causes of oxidation clip slag of aluminum castings are as follows: (1) the furnace material is not clean, the use of the furnace material is too much; (2) the design of the pouring system is bad; the slag in the alloy liquid is not cleaned up; (4) the pouring operation is not appropriate, and the slag is brought into the slag; 5.
prevention measures: (1) the furnace material should be blown through sand, the use of the furnace material should be reduced appropriately; (2) improving the design of the gating system and improving the slag retaining capacity; (3) using the appropriate flux to remove slag; (4) the casting should be stable and stop the slag; 5. .
