Latest Patents
Higashi holds a patent for a "Billet by continuous casting and manufacturing method for the same." This patent addresses the production of billets with minimal central segregation, specifically focusing on high carbon steel. The method involves reducing the size of the dendritic equiaxed crystal in the central portion of the billet to no more than 6 mm. To achieve this, electromagnetic stirring is utilized to increase the inclining angle of the primary dendrite within 10 mm of the billet surface layer to at least 10 degrees. Additionally, mechanical soft reduction is performed during continuous casting to minimize the diameter of center porosity in the billet's central portion to no more than 4 mm. This innovation is particularly beneficial for manufacturing billets with a carbon content of at least 0.6% by mass and a size not exceeding 160 mm, as it reduces breaking troubles in wire drawing after rolling to a rod.
