Since the cross-sectional area of the longitudinal member 48 is approximately 1/2 of the cross-sectional area of the cooling water passage 11a, when the longitudinal member 48 is inserted, the area of the cooling water passage becomes This is about 1 to 2 of the cooling water passage area when 8 is not inserted. In other words, the cooling water flow rate can be reduced to half for the same cooling area, and the cooling efficiency is greatly improved. Fig.
- FIG. 11 shows a case where a longitudinal member 49 with a star-shaped cross-section is approximately the same size as the length of the cooling water passage 11a is inserted into the cooling water passage 11a of the mouth body 11
- the cross section of FIG. since the cross-sectional area of the longitudinal member 49 is larger than 1/2 of the cross-sectional area of the cooling water passage 11a, the area of the cooling water passage when the longitudinal member 49 is inserted is The cooling water passage area is smaller than 1/2 of the area of the cooling water passage when no passing material 49 is inserted.
- the cooling water flow rate is less than half for the same cooling area, and the cooling efficiency is greatly improved.
- the cooling water passage area is reduced by inserting longitudinal members that have a star-shaped cross-section that does not significantly increase the flow resistance of the cooling water, not limited to the above triangle and star shapes, and improve the cooling efficiency As a result, the size of the mouth body can be further reduced.
- a heat treatment roll having high rigidity and good heat transfer efficiency can be provided.
