の鋳型が提案されている。Recently, high-speed casting (for example, 5 m / min or more) has been pursued in order to increase the productivity of continuous casting. However, in high-speed casting, the heat load of a mold becomes a problem. In particular, the temperature of the mold copper plate near the meniscus where molten steel comes into contact increases significantly,
There is a risk of operating trouble such as breakout. Therefore, various molds have been proposed to enhance heat removal near the meniscus.

ど増大する。As shown in FIGS. 1 (a) and 1 (b), a cooling water passage 7 extending from the lower end of the mold copper plate 1 to the upper direction of the mold copper plate 1 has a plurality of cooling water passages near the meniscus 10. It is branched into a branch waterway 8 (in FIG. 1, two branch waterways are illustrated). Heat removal by passing water through the cooling water channel
It increases as the surface area of the cooling water channel increases and as the water flow speed increases.

はＮ1/2 倍に増加する。すなわち、Ｎ＝２で１．４倍、
Ｎ＝４で２倍となる。Therefore, by branching the cooling water passage in the mold as shown in the figure, the surface area of the water passage per unit length of the mold in the drawing direction is increased, and as a result,
The amount of heat removed from the branched part increases. For example, assuming that the total cross-sectional area of the branch waterway is constant and the number of branches is N, the total surface area of the branch waterway increases by N1 / 2 times as compared with the case where no branch is made. That is, N = 2, 1.4 times,
N = 4 is doubled.

50mm to 150 downward from high meniscus equivalent position
mm. The branch position is 50mm
Above this point, the heat removal effect due to branching is insufficient,
Below 0 mm, pressure drop increases due to decrease in cross section of water channel
This requires an increase in pump capacity.

As shown in FIG. 1A, the cooling water is supplied from a lower header 5 through a water supply port 14 and is discharged from a cooling water channel 7 through a branch water channel 8 to a drain port 9 to the upper header 6. When the cooling water passes from the cooling water channel 7 to the branch water channel 8, the cross-sectional area becomes small, so that the flow rate of the cooling water increases, and the heat transfer on the water channel surface is promoted. Become.

少して充分な抜熱効果が得られない。Here, more preferably, the total cross-sectional area of the branch channel is 30% in terms of a cross-sectional area ratio with respect to the lower cooling channel.
That is all. If the cross-sectional area ratio is less than 30%, the circumferential length of the branch channel becomes extremely short, and the heat transfer surface area of the branch channel is significantly reduced, so that a sufficient heat removal effect cannot be obtained.

面積の増加の点では有利であるが、構造が複雑になる。Next, the specific shape, dimensions and number of branches of the branch waterway will be described. The mold copper plate 1 is usually about 50 mm thick, and both water passages are provided in a range of 15 mm or more and 30 mm or less in the mold thickness direction from the mold inner surface 12, and the lower cooling water passage has a diameter of 10 mm or more and 30 mm or less. It is desirable that the circular cross section of the above and the upper branch water channel have a circular cross section having a diameter of 3 mm or more and 5 mm or less, and the cross sectional dimensions of the branch water channels be the same. Normally, the number of branches (N) is sufficient if two or three. Four or more are advantageous in terms of increasing the surface area of the water channel, but complicate the structure.

In the slit type, a cooling channel is formed by a slit formed on the surface of a mold copper plate and a backing plate called a back frame. Although the present invention has been described with reference to the mold having the through-hole type cooling water channel as shown in FIG. 1, the present invention can also be applied to a slit type cooling water channel mold.

It will be 50 ° C. Since this temperature is close to the softening point of the copper plate of 400 ° C., it is a condition under which breakout is likely to occur, which is dangerous for operation and safety. In Examples 1 to 3 of the present invention, the temperatures at the measurement points were all 185 ° C or lower, and the estimated surface temperature of the mold copper plate near the meniscus in contact with the molten steel was about 300 ° C, and stable operation was possible.
