Title: Method and apparatus for continuously casting directionally solidified cast billet
Inventor: SAMEJIMA MASAHIRO
IPC: B22D11/06
Filed: 1988-06-17
Abstract: PURPOSE:To obtain uniform directionally solidified structure at the whole range of cross section in a cast billet by solidifying molten metal in a cylindrical nozzle constituting as mutually integrating divided mold members to obtain the cast billet and drawing out this cast billet to out of a vessel at the same velocity as shifting velocity of the divided mold members. CONSTITUTION:A starting rod 14 is inserted in the nozzle 11 through opening part 3 of the vessel 1 at the same time of starting shift of the belts 5, 6. At the time of charging the molten metal 2 into the vessel 1 while cooling a rod 14 with cooling water for the nozzle 12, the molten metal is invaded into the nozzle 11 surrounding with the divided mold members 9, 9 and brought into contact with the rod 14 and cooled and stuck to the rod. The molten metal 2 temp. is lowered by conducting the heat only to the direction toward the rod 14, to obtain the cast billet having directionally solidified structure. By drawing the rod 14 from the vessel 1 at the same velocity as the shifting velocity of the mold members 9, 10, the solidifying cast billet is drawn to out of the vessel 1 at the fixed velocity and cooled with the cooling water for the nozzle 12. By this method, the breakout is reduced and the uniform directionally solidified structure is obtd. and the casting can be executed at high velocity.
