Latest Patents

Hiroyoshi Sakai holds a patent for a "Method for supplying rolling oil for cold rolling." This method involves the use of emulsion rolling oil supplied through two distinct systems. The first system operates in a recirculation mode, supplying oil to both the roll and the steel sheet being rolled. The second system specifically targets the front and back surfaces of the steel sheet. Notably, both systems utilize emulsifiers of the same type and concentration, with the second system designed to produce larger average particle diameters of emulsion compared to the first. This innovative method ensures that the emulsion from the second system, which does not adhere to the steel sheet, effectively combines with the emulsion from the first system.
