り。In horizontal continuous casting, a mold with a water-cooling jacket is directly connected to the side of the kundish, and the molten steel flowing into the nozzle 'tip mold of the tundish from one end is indirectly cooled to form a solidified shell and converted into a slab at the other end. In order to accomplish this process, the molten steel flows from the inlet end of the mold to the desired position of the flow into a solidified shell shape bj! ,'t-It is a formality to start.

ようにしＴこことを特徴とする。The present invention has been developed to solve these problems, and is a mold cooling water supply device for horizontal continuous casting that does not cause water condensation in the mold during preheating of the tundish. Directly from the ML tundish, the nozzle provided on the side wall is bent to cool the melt in the mold.
In a horizontal continuous casting machine that horizontally pulls out 1 clJ+ of slabs that form shadows, cooling water is supplied to the mold from a hot water tank equipped with a temperature raising device, and a hot water supply system with a temperature of 40°C or more and less than 100°C and a low temperature one. There are two lines for the cooling water supply system, and a temperature control device is installed on the mold wall so that the mixed water supply can be automatically switched from the mixed water supply to the cold water supply depending on the detected temperature.

In general, the jacket and needle cooling channels in the mold of horizontal continuous casting are constructed in a complicated manner, and because of the horizontal arrangement, it is extremely difficult to ensure that there is no accumulation of cooling water. There is a risk of a steam explosion as it is necessary to provide a mold pulley that can withstand the generation of heat.Furthermore, QIJ rings with a heat resistance of around 100°C are often used as seals inside the mold, so they are susceptible to burnout due to external heating. Water leaked inside the mold! There is also a risk of an explosion occurring.

に行うことができる。As described above, according to the present invention, hot water of 40°C to 100°C is poured into the mold jacket until the start of casting to raise the temperature of the mold. It also prevents condensation. Furthermore, since there is no sudden temperature change in the PC when the molten M is inserted, the strain that occurs in the mold can be reduced, so the chances of water leakage due to mold distortion can be reduced. In addition, by raising the temperature of the mold to an appropriate temperature before storing it, it is possible to reduce the amount of pressing ii of plaque rings, etc., making it easier to manage them. Furthermore, by providing a temperature detector on the mold wall to detect when molten steel flows in, it is possible to easily switch between hot water and low-temperature cooling water.

して、Ｗ、定条件で連［９造を実施することができる。The cooling water inlet temperature can be controlled to be always constant at an optimum value of, for example, 80°C as a set value, and this optimum temperature is determined by the temperature from the molten steel temperature sensor (44) and mold wall temperature sensor (88) in the tundish (2). It can be determined by converting the detected temperature ## as data and inputting it into the calculator (89A). In continuous casting, as mentioned above, in many cases, cold water from a water cooling tower is used as cooling water for the mold. Since a water cooling tower cools most of the hot water using the large latent heat generated by the evaporation of a portion of the hot water, the temperature of the cold water changes depending on the humidity of the outside air. In general, cooling towers are equipped with R under outside air conditions in the summer, and there is a tendency for excessive cooling to occur in the fourth period, so if the mold cooling water humidity becomes too low, there are many cases of 2.Especially during long-term cold weather or after holidays, Temperature is low. kot'
For LVc, in the example shown in Figure 2, convert the data of the hot water temperature in the hot water tank and the low temperature cooling #iA degrees from the water cooling tower, and input the VC to the calculator (89A), -1
Here, by controlling the mold cooling water inlet temperature R to a specified value, it is possible to carry out continuous manufacturing under fixed conditions.
