As shown, the cooling water spout end is at the center of the pulley 54, and the 1. = 1 at the bell, therefore, when the belt 50 is stopped, the range of distance 1) between the position away from the circumference JIJ of the pulley 54 and the position where the cooling water hits remains uncooled. Straddling the belt 50 and stopping the belt 50, insert the pouring nozzle 56 into the αJJ as indicated by the dashed line, and as you insert it, the pouring nozzle 56 has already been preheated, so its heat dissipation causes The belt 50 in the A-reduction portion is heated, causing local thermal deformation.A similar problem also occurs in the belt 511 on the left side.

On the other hand, before stopping the belt and entering the casting mode,
A pouring nozzle from a tundish or the like is inserted into the two ends 1 of the casting space created between the belts. Since this pouring nozzle is preheated, when it is inserted, the belt is heated by heat radiation. On the other hand, cooling water is continuously jetted from the cooling water jetting device for the time period from the insertion of the pouring nozzle to the start of running of the belt.

Therefore, the belt starts running without deformation or thermal distortion, and thereafter operates while being continuously cooled by cooling water from the cooling nozzle.

。Furthermore, when the belt moves at a high speed, the time it takes to pass through the range r) where the cooling water is not applied becomes short, and even if the cooling water is turned off, the belt will not be deformed or thermally strained due to the heat dissipated from the nozzles. , [Example] Fig. 1 is a vertical cross-sectional view of the main part of the present invention shown in Fig. FIG. 2 is a vertical cross-section of the upper end of the belt-type continuous casting device.

いる。In FIG. 3, a pair of metal belts 1 and 2 are wound around pulleys 3 and 4, as described in the conventional example, and these belts 1 and 2 are connected to drive boots (not shown), respectively. Move in the direction of arrow 11.1 in the figure with the help of Zun 1. Then, the gap that comes to the bus part in the vertical force direction is used as a casting space, and the pouring nozzle L5 is inserted into this space 3. Furthermore, a fin roll 6.7 is embedded on the 1 side of the pulley 3.4 to receive the back surfaces of the belts 1 and 2 and prepare the casting space.

On the surface of the cooling header 9 facing the back side of the belt 1.2, jet holes 971 are opened in the direction 1'j, with the 1-'i] axis slightly parallel to J- in the horizontal direction. These jets 7+; are provided between adjacent cooling nozzles 8, as shown in FIG. 2, and are located at a higher position than the jets at the lower ends of the cooling nozzles 8.

This spouting of cooling water from the cooling pad 9 is carried out during the time period from the process of inserting the pouring nozzle 5 to the time when the bell 1.2 is run to start continuous casting work. This is because when the preheated pouring nozzle is inserted into the hole shown in Figure 141, the belt 1゜2 becomes hot due to the heat dissipated in ①, so this is cooled down by the ladder 9.

In contrast, the cooling header 9 cools the back surface of the belt 1.2 on the pouring nozzle 5 side, which cannot be cooled by the cooling nozzle 8. Therefore, deformation of the belt 1.2 at the start of continuous casting work can be prevented. Therefore, the cooling nozzle 8 has a cooling power of 1.
Similar to the part 1.2, there is no deformation of the bells 1-1 and 2 even though the metal is poured and the heat is dissipated from the nozzle 5.

In this way, compared to the conventional structure, the quality defects that occur every time the deformed parts of the belts 1 and 2 pass through the casting space are eliminated.In addition, the belts 1 and 2 themselves also suffer from distortion, etc. It operates without any problems 5, 7, and durability is improved 1. At the same time, the frequency of replacement is reduced and the operating rate is improved. Insert 2
During pouring, the portion heated by the pouring nozzle is cooled by a cooling water jetting device, in addition to steady cooling by the cooling nozzle. This prevents the belt from being partially deformed by the heat from the pouring nozzle before running the belt, and improves the surface quality of the cast iron to be cast. 1゜(2) The deformation of the bear 11- itself ←, the initial J)(" heat release I+ is also suppressed, so the durability of the belt is also improved. , -J exchange, the conventional structure is 1
