Yes it requires more time as section thickness increases. However it also depends on the Alloy addition , Hardness and properties required , Sand to metal ratio etc.
It is due improper arrest of inclusions like sand and slag in gatting system. Use of filter , Proper overlapping or providing chock can help you in arresting such inclusion.
I already have made seperate videos on Peralite grades and Ferritic grades ductile iron where the bath and final chemistry are notified. I will share the links for both.
CRCA means cold rolled close annealed, as said before that metal is rolled in temperature below recrystallization level, cold rolled are much harder and have smootherfinish than hot rolled metal.

Very nice. Easy and simplified notes.
Good teacher
Very informative video sir...
What should be the final min and max value of C and Si for 10 to 15 mm wall thickness in s.g. Iron casting
Please suggest
More section thicknes ... So we need more cooling time sir ?

Sand inclusion is seen after machining by 2 - 3mm,
# why does the non core casting getting the sand inclusion after machining, what's the remedy?

How can find bath and final chemistry for other grade cast iron??

Good,sir kindly say 500/7 SG grade means
Sir vidio mast ahestat pn thode marathit pn banvle tr amhala samjnyas bre hoil
Yes we will be doing some of these videos in Marathi as well.
Sir what is the full form of CRCA
CRCA means cold rolled close annealed, as said before that metal is rolled in temperature below recrystallization level, cold rolled are much harder and have smootherfinish than hot rolled metal.
What should be maximum nodule count
There is no such specification but one can aim upto 400-500 max. Above that acheiving nodule count is very tough job
@@dynamicfoundrygroup sir what would be significant if nodule count is above 500
It may results in increase in shrinkage tendency.
@@dynamicfoundrygroup thanks sir
Sir I required 600/10 Grade please chemical composition.
Please ask this on the DFG Whatsapp group.
