E nder spindle, maa won kadi ɓuuɓri e nder kiriis shaft, e nder ɓuuɓri billet caggal ɗuum, maa ɗum heddo e nder ɓuuɓri ndii hono ɓuuɓri nder ɓuuɓri ndii.

4. Wirtinde ɓalndu nduu

Ɗuum ko steelmaking gila e ladle haa e ingot ɓuuɓnude ingot, sabu ruttaade taƴre, pause, ruttaade e dow njamndi ndiyam e nder henndu jaawndu coofgol mbaydi oksidaa filmo, keso ruttaade e nder njamndi ndiyam mbaydi e nder ɓanndu ingot e mbaydi hierarchical (area) defects forgettque, ɗum e nder ingot wonaa forlletting for.

5. Anisotropi
