Latest Patents

Yukako's latest patents involve a cutting-edge production equipment line for hot-rolled steel strips that integrates innovative technologies to enhance efficiency and quality. This system comprises a rough rolling mill that includes plural rough rolling mills designed to hot roll a material that is preheated to a specific temperature, preparing it for the finish rolling process. Moreover, the equipment features a finish rolling mill that facilitates controlled rolling to achieve the desired final sheet thickness. Notably, at least one of the rough rolling mills is a reversible rolling mill, which adds flexibility to the manufacturing process.

Additionally, the production line is equipped with both a slow cooling apparatus and a rapid cooling apparatus, strategically positioned to optimize cooling phases. The slow cooling apparatus operates at a water volume density of less than 1000 L/min·m, while the rapid cooling apparatus is capable of quickly cooling the material after the slow cooling process, operating at a water volume density of not less than 1000 L/min·m. This innovative approach not only improves the quality of the hot-rolled steel strips but also enhances the overall production efficiency.
