この発明は、鋳型に注入された金属湯の均一冷却性を高
めたベルトホイール型連続鋳造機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a belt-wheel type continuous casting machine that improves uniform cooling of metal hot water poured into a mold.

ルから供給冷却水を噴射して鋳型の表面に吹きつける。A belt wheel type continuous casting machine rotates a casting ring having an outer circumferential groove and an endless belt that contacts the outer periphery of the casting ring in a part of the circumferential direction, and inserts one side of the mold into an arcuate mold formed between the two. Metal hot water such as molten steel or molten aluminum is injected from the open end of the mold, and a continuous ingot is obtained from the other open end of the mold. In this casting machine, a cooling manifold is arranged along the mold in order to cool the metal molten metal poured into the mold, and cooling is supplied to this manifold from nozzles installed at a predetermined pitch in the circumferential direction of the casting ring. Spray water onto the surface of the mold.

而の冷却が不均一になるので、各マニホールド内水圧を
測定し、この測定値に基いた加減圧調整で上記の水圧差
を少なくする方法が採られている。At this time, the mold is cooled by adjusting the distance from the nozzle to the mold to be approximately constant in order to reduce uneven cooling at various parts in the circumferential direction. In addition, the cooling is usually carried out on each surface of the mold, that is, both end surfaces of the outer peripheral part of the casting ring, the inner surface of the casting ring,
This is done on four sides of the endless heald, but if there is a water pressure difference between the four manifolds that are placed along each side separately,
Since the cooling becomes uneven, a method is adopted in which the water pressure inside each manifold is measured and the pressure is adjusted based on the measured value to reduce the water pressure difference.

の生じた不良鋳塊が発生している。The water fountain pressure from the nozzle is influenced by internal resistance of the manifold and the like. Therefore, the method of keeping the water pressure between the manifolds constant and the distance from the nozzle to the mold cannot completely avoid the difference in water jet pressure between the nozzles. For this reason, the cooling of the metal molten metal in the mold becomes uneven, and shrinkage strain caused by the uneven cooling acts on the solidifying metal, resulting in defective ingots with cracks and the like.
この発明は、上記の課題を解決するために、ベルトホイ

水圧を測定する圧力センサを取付ける。また、各ノズル
には噴水圧の調整機構を付加する。In order to solve the above problems, the present invention attaches a pressure sensor to the mold of a belt-wheel type continuous casting machine to measure the water jet pressure from the cooling water injection nozzle. Additionally, each nozzle is equipped with a fountain pressure adjustment mechanism.

果を確実に均一化することができる。If a pressure sensor is installed in the mold, the water fountain pressure from each nozzle can be measured. Moreover, if there is a fountain pressure adjustment mechanism, the fountain pressure of each nozzle can be adjusted individually. Therefore, through this adjustment, the water jet pressure from each nozzle arranged in the circumferential direction of the casting wheel facing the surface to be cooled can be made constant, thereby reliably making the cooling effect uniform in each part of the mold.
なお、ノズルの配列方向は鋳型の回転方向と一致してい
るので、圧力センサは１マニホールド当りに１個（４面
冷却では計４個）設ければよい。Note that, since the direction in which the nozzles are arranged coincides with the direction of rotation of the mold, one pressure sensor (total of four in four-sided cooling) may be provided for each manifold.

The spray pressure of each nozzle 10 between the inlet and the outlet of the mold is sequentially measured. By adjusting the spray pressure of each nozzle based on the measured value, the spray pressure of all the nozzles becomes almost equal, and cooling is uniformly performed on the four sides of the mold and at each part in the circumferential direction. Therefore, the metal molten metal solidifies evenly, shrinkage strain is reduced, and a stable ingot is obtained.
