Hello everyone, I am the youngest girl in the factory.
What are the specific measures to reduce or eliminate carbides
in thin-walled ductile iron?
Today I will teach you six methods,
remember to follow, like, and favorite~
First, strictly select pure charge to reduce the introduction of carbide elements;
Secondly, strictly control the melting temperature and overheating temperature;
Third, improve CE; use pretreatment processes such as silicon carbide;
Fourth, select low magnesium and low rare earth nodularizers
to reduce residual magnesium and residual rare earth content;
Fifth, reduce the diameter of the sand particles or
use a heat-resistant sand mold;
Finally, just remember to increase the number of graphite balls.
Among them, increasing the number of graphite nodules
is an effective measure to eliminate the occurrence of
intergranular carbides in thin-walled ductile iron.
Follow me, the youngest girl in the factory.
In the next issue, we will talk about measures to increase
the number of graphite balls in thin-walled ductile iron~
