Time=6/0.1=60 seconds Min rising velocity=78/60=1.3cm/s Particles>=0.2 mm will all reach the surface. ** Casting ** Time need to solidify: (d/k) squared = ((225/2)/25)squared=20.25 minutes( solidification is from two sides so 225/2) Distance is 20.25*1.5=30.375m. Tonnage per minute=2*0.225*1.3*1.5*7=6.1425 ton/min. In a year :6.1425*60*24*365*0.9=2.9 mton. HR- Lenght= 10.8*225/2.5*0.98=952.56 meter. Cr-lenght=952.56*2.5/0.22=10824.5 meter. Wall thickness=0.22/3=0.07333. Max inclusion size 0.02444 mm= 24 nano meter
