high chromium white cast iron nucleation

Hi there,

I m a material engineer and work in a foundry. we produce high chromium white cast iron abrasive balls.

we cannot use %100 returns in smelting due to inhibition of starting nucleation.

But we use pig iron for starting nucleation grey-ductile iron smelting.

i want to produce high chr white cast iron with %100 returns

is it possible to add pig iron into high chr white cast iron melt for starting nucleation

sorry for my bad english :)

thanks for replies.
