Hello everyone, I am the youngest girl in the factory.
There are 6 basic points for choosing a suitable spheroidizer,
 and today we will talk about the remaining three points;
4. Handling weight
If the weight of the molten iron after treatment is less than 500 kg, 
a spheroidizer with a smaller particle size can be used. 
It is recommended to use a spheroidizer with a particle size below 12MM.
If the weight of the molten iron after treatment is 500 ~ 1000 kg, 
a nodulizer with a larger particle size can be used, 
such as a particle size of 5 ~ 25MM.
If the weight of the treated molten iron exceeds 1000 kg,
 a nodulizer with a particle size of 5 ~ 32MM can be used.
5. Silicon content
If the process yield of casting products is low or the scrap rate is high,
 it is necessary to add more charge and scrap for smelting, 
and castings have strict requirements on the silicon content of molten iron.
 On the premise that the amount of inoculation cannot be further reduced, 
a low-silicon nodularizer can be used for treatment, 
which can increase the amount of returned material by 8% to 15% 
and reduce the production cost of the foundry.
6. The sulfur content of the original molten iron. 
If the sulfur content of the original molten iron is high,
 if the desulfurization treatment is not carried out, 
a nodulizer with high magnesium and high rare earth will be required, 
and the addition amount will be higher.
The spheroidizing agent produced by 
Nanjing Difeng has optimized raw materials,
 quality assurance, and can also be customized 
according to the standards required by customers. 
Welcome to consult and place an order.
Follow me, the youngest girl in the factory, 
see you next time, bye~
