Hello everyone, I am the youngest girl in the factory.
Today, I will tell you how to deal with the small number of
graphite balls and the uneven diameter of the balls.
If there is nodular graphite, the residual Mg content is no problem.
The problem is that the breeding is not good or the breeding is declining.
If the casting does not produce white mouth,
it means that the breeding gap is not big.
From the point of smelting, the graphite core should be controlled with
artificial graphite C increasing agent.
Industry insiders recommend that SiC is better than artificial graphite.
And pointed out that SiC is light in weight, easy to float,
and the surface is blocked by SiO2 film,
which affects the dissolution.
Therefore, it is better to add SiC during the feeding period.
If the silk feeding method is used,
the inoculation must be carried out after the end of the spheroidization,
so as to avoid the accelerated decline of the inoculation.
Follow me to learn more about casting knowledge,
see you in the next small class.
