Description
【発明の詳細な説明】 （産業−１−の利用分野） 本発明は、連続鋳造用鋳型の鋼壁の製造方法に関する。[Detailed description of the invention] (Application field of industry-1-) The present invention relates to a method for manufacturing a steel wall for a continuous casting mold.

る。(Prior Art) In continuous casting, molten steel is poured into a mold from a tundish, cooled on the surface in contact with the mold, and forms a solidified layer. The solidified slab is drawn downward while containing unsolidified molten steel, is water-cooled in a secondary cooling zone, and is completely solidified.
交流磁界による電磁気的な力で撹拌することにより、鋳
片の内部性状の向上を図るため、広く採用されている。This method is widely used to improve the internal properties of slabs by stirring them using electromagnetic force using an alternating magnetic field.
電磁撹拌用ソレノイドは、必要に応じて、鋳型や二次冷

交流電源を用いて、より大きな電磁撹拌力が得られるし

分となり、連続鋳造のコストの低下に役立つ。The magnetic field generated by the solenoid decays rapidly as it moves away from the solenoid. The stirring force acting on unsolidified molten steel is
It is proportional to the magnitude of the magnetic field at the position of unsolidified molten steel (more precisely, to the product of the magnetic field and the differential of the magnetic field with respect to the position coordinates). Therefore, it is desirable that the distance between the solenoid and the unsolidified molten steel be as short as possible. If this distance is short, a larger electromagnetic stirring force can be obtained using the same AC power supply for electromagnetic stirring, and a smaller current is sufficient to obtain the same stirring force, reducing the cost of continuous casting. useful for.

劣るので、コストか高いという欠点がある。Diffusion welding is a special joining method. In this method, the copper plate and the back plate 1 are brought into close contact with each other under pressure, and then they are joined by heating in a vacuum or in an inert gas. With this bonding, the thickness of the copper plate can be reduced, and also...
Unlike the two conventional examples described above, there is no need for a space for bolt fixing. Therefore, there is an advantage that the electromagnetic stirring device can be installed near the slab. In the case of hydrogenation, a vacuum heating furnace, a pressurizing device, etc. are required, and the productivity is extremely low, so there is a drawback that the cost is high.
