This is the spheroidizing agent just produced by the masters.
The advantages of the nodulizer are undeniable,
but if used improperly,
it will not only fail to play the role of the nodulizer,
but also cause inevitable losses.
So what are the consequences if the nodulizer is used incorrectly?
1. Spheroidization decline:
This is because the spheroidized molten iron stays for a long time,
the residual magnesium gradually decreases,
the slag is not removed in time, and the sulfur will return to the molten iron,
which reduces or even disappears the graphite in the solidified structure,
and decays into a non-ferrous metal.
Regular, worm-like or flake graphite.
2. Black slag: It generally occurs in the upper part of the casting and
is mainly divided into block, rope and fine black slag.
3. Shrinkage porosity shrinkage porosity:
Shrinkage cavities often appear
in the final solidification part of the casting,
which are holes hidden inside the casting or connected to the surface.
Follow me, the youngest girl in the factory,
which method do you usually use?
