Hello everyone, I am the youngest girl in the factory.
Today we will talk about:
what problems will be encountered in the manufacture of
thin-walled ductile iron castings?
First of all, let's take a look at thin-walled ductile iron castings.
We usually refer to castings with a wall thickness of
3-6mm as thin-walled ductile iron.
With the advancement of technology,
today's thin-walled ductile iron has been reduced to
2.5mm in defined wall thickness.
When manufacturing thin-walled ductile iron castings,
it is often encountered:
when the molten iron is insufficiently filled,
it is prone to insufficient pouring, cold isolation;
formation of carbides, white mouths; inclusions and other defects.
These problems are all related to the excessively fast
solidification rate of thin-walled ductile iron.
As the wall thickness decreases,
the cooling rate increases significantly.
According to the test data,
the cooling rate of 2-3mm castings is 15-20 times higher than
that of general 15mm castings.
Follow me, the youngest girl in the factory.
