The The methods methods of of reducing reducing defective defective percentage percentage of of steel steel casting casting parts parts Steel casting parts will have some defect parts during casting,although we can’t avoid it,we can reduce defective percentage of steel casting parts. Parfect Casting Co.,Ltd a exported company which mainly produces all kinds of casting steel,alloy steel,stainless steel.Now let’s talk about the methods of reducing defective percentage of steel casting parts. is 1. Casting on the wall of the casting hole, should be reinforced with a convex edge to reduce the wall thickness 2. The structural of casting parts should cooled allow it to shrink unhindered when 3. the waterway, gas funnel and other large sandwich chamber of internal casting, there should be a number of connecting columns 4. The connection between the wall and the wall of the casting should prevent sharp corners and metal agglomeration. the thick wall and the thin wall should be transited gradually , so as to avoid abrupt change and and stress concentration hot spots 5. The part of thick fracture surface of steel casting parts should be used hollowed out or cast in hole structure as far as possible,and use reinforcing rib to strengthen
6. The wall thickness of steel casting parts should be uniform, to prevent shrinkage, thermal cracking, when need to ensure the order of solidification conditions, it should try to make it in a direction of change in wall thickness, when need to ensure the same time solidification conditions, should try to make Which has an equal section wall thickness.
