(1) In the first invention, when constructing a sprue, in principle, a single pipe-shaped brick that is extruded and cut into a predetermined length is used. For this reason, the work which requires skill and man-hours for stacking a large number of brick elements by mortar connection as in the conventional art is basically unnecessary. In addition, the total length of the sprue brick is set accurately, and post-preparation of the sprue height is substantially unnecessary. Therefore, the time required for constructing the gate can be shortened significantly as compared with the conventional one.

(3) It should be noted that Japanese Patent Laid-Open No. 53-113716 describes that the sprue is formed integrally with a molding brick, and the molding brick here is "extruded molded". It does not refer to "pipe bricks". That is, the sprue brick of the cited example is obtained by press-molding and firing, and then joining several pieces with mortar or the like, and winding a hoop around that portion to integrate them.
