Abstract

PURPOSE: To provide a pleated projection or groove for the surface of the freeze seal gutter and feeze seal dam for improving the sealing property without increasing the seal alloy.
CONSTITUTION: The projection 24 is provided for the inner wall surface of the freeze seal gutter 21 mounted on the side of the fixed plug 11 and the wall surface of the freeze dam 22 mounted on the side of the revolving plug 10 by welding to attach the structure member of a rectangular cross section is a peripheral direction. This allows the seal direction length of mating section of the seal alloy 23, the freeze seal gutter and the freeze dam 22 wall surface to increase, securing the similar effect with increasing the pouring height of seal alloy 23 increasing the volume of the seal alloy 23. Further, the similar effect enables to secure even the groove is provided instead of the projection 24
