Hello everyone, I am the youngest girl in the factory.
"Interfering elements" are those that have a negative effect
on the properties of gray cast iron and ductile iron,
and are not necessarily the so-called harmful elements.
There are three sources of interference elements:One is the harmful elements usually contained
in steel castings and iron castings,
such as sulfur, phosphorus, lead, etc.;
The second is alloying elements specially added to
improve the properties of steel,
such as manganese, chromium, molybdenum, etc.;
The third is the pollutants mixed in the charge.These "interfering elements" have a great influence
on the properties of cast iron,
and will form carbides, affect graphite spheroidization,
increase the tendency of shrinkage cavities,
and reduce the strength of gray cast iron, etc.
Follow me and I will tell you the solution in the next issue.
