In view of the above-mentioned circumstances, the present invention was developed as a result of intensive research, and instead of providing a stud on the post 1 and covering the area around the stud with a castable material 2, the post 1 is made of metal 3.
The surrounding area is covered with castable 4, which penetrates the shield plate and can be moved up and down, and the shield plate is provided with a support so that it can slide over the hearth to prevent heat radiation or cooling. This is what I did.

In the present invention, as shown in FIG. 2, a walking beam post 1 has a metal 3 covered with a castable material 4, which passes through a heat shielding plate 5. The heat shielding plate 5 may be a single piece, but as shown in FIG. 3, it may be divided into two pieces and joined together at the portion where the post 1 penetrates. Further, the heat shield plate 5 is placed on a support 6. The support 6 is made of the same material or a softer material than the heat shield plate 5.
The heat shield plate 5 is made of SiC, A 2 O 3 −SiO 2 SiC−Si 3 N 4
Composite, made of ceramics such as Si 3 N 4 . To attach the heat shield plate 5 and the support 6, a desorption stopper 7 is provided on the heat shield plate 5 as shown in FIG. In FIG. 4, the desorption stop 7 is provided on the inside of the support 6, but the desorption stop 7 may be provided on the outside and the support 6 may be provided on the inside. to prevent heat dissipation and cooling.

If the surface that comes into contact with the heat shielding plate 5 is made into a convex surface such as a cylindrical shape, the resistance can be reduced, and the convex portion may be prevented from moving away from the heat shielding plate 5 when vertically moved.

In this invention, the heat shield plate is formed larger than the hole provided in the hearth, and the post is passed through the heat shield plate.
It is configured to be able to move up and down, so only the post moves up and down, and the heat shield remains the same.When the post moves back and forth, the heat shield also slides on the support and moves back and forth. is something that never wears out.

を完全に塞ぎ、放熱および冷風の浸入がない。 In addition, by attaching ceramic to the post and forming the surface of the ceramic that comes into contact with the heat shielding plate, that is, the area around it, into a convex surface, there is less resistance to the heat shielding plate when the post moves up and down. , it can also be formed without being separated from the heat shield plate. In addition, the heat shielding plate completely closes the hole provided in the hearth, preventing heat radiation and cold air from entering.
