Document Type and Number:
Japanese Patent JPS62238047
Kind Code:
A
Abstract:

PURPOSE: To improve the spreading property and the fatigue strength and also to improve the durability at high temp. by keeping temp. of the inner wall of a mold for continuous casting higher than solidified temp. of molten alloy metal and executing the solidification of the surface of a casting billet at just out of the mold.

CONSTITUTION: The molten metal is supplied into the mold 1 through a trough or a molten metal supplying tube 4. The casting billet 8 is cast continuously in successing the end top of dummy casting block, as cooling by a cooling device 6, which cools the dummy casting block 5 by water or mist, gas, etc., and as descending by pinch rolls for drawing the casting billet. At the time of casting, the temp. of the inner wall 1a of the mold 1 is kept to more than solidified temp. of the molten metal 2, to become to solidify the surface 8a of the casting billet 8 at just below the mold 1.
