Latest Patents
Hatae holds a patent for a method of producing a cold-rolled steel sheet that exhibits excellent properties. The patent describes a process that involves continuously casting, hot-rolling, cold-rolling, and continuously annealing Al-killed steel. A key aspect of his invention is the use of a high coiling temperature of at least 780°C, which prevents aging due to the precipitation of AlN. This method also ensures that the carbon content of the continuously cast slab is kept at a maximum of 0.005%, effectively preventing the occurrence of orange peel. His innovative approach allows for heat conservation and results in superior properties of the cold-rolled steel strip.
