Latest Patents

Tsuchiya's latest patents include a cooling mechanism designed for use in continuous metal casting. This innovation features at least two exhaust holes formed in an atomizing nozzle, which sprays an air-water mist for cooling. The mist streams from the exhaust holes cross each other before reaching the surface of a cast strand, allowing for effective diffusion due to the kinetic energy directed in the spraying direction. This design ensures that the air-water mist sufficiently enters the region between the surfaces of guide rollers and the cast strand, providing comprehensive coverage for cooling. Additionally, a header is positioned parallel to the guide rollers, with multiple water branching pipes attached in line. The inner diameters of these pipes decrease sequentially, which helps reduce back pressures in the atomizing nozzles, resulting in a uniform flow rate of water from each pipe.

Another patent involves an apparatus for spraying an air-water mist for cooling in continuous metal casting. This design includes an exhaust hole in the exhaust side wall of a mist atomizing nozzle, along with an introduction inlet on the opposite side. An air-water mixture supply pipe is connected to this inlet, allowing for the introduction of a mixture of relatively large water droplets. The design ensures that these droplets are finely atomized within the nozzle and sequentially exhausted, enhancing the cooling process.
