Latest Patents

Yamakawa holds a patent for a process titled "Process for hot working continuous-cast bloom and steel ingot." This process involves several critical steps: first, cooling a bloom produced by continuous casting or a steel ingot to a surface temperature that is 50 to 150 degrees Celsius higher than the Ar₃ transformation point. Next, the bloom or steel ingot is quenched in a manner that allows its interior to remain red hot while the surface transforms to a bainite structure. Finally, the bloom or steel ingot is heated in a furnace followed by hot shaping. This innovative process enhances the quality and performance of steel products.
