Latest Patents

Her most recent patents focus on improving the production and quality of hot-rolled steel sheets. One of her notable patents describes a hot-rolled steel sheet that ensures it does not exceed the coil opener allowable load during unwinding. This patented design allows for a steel sheet that is cut in unsteady portions at its longitudinal head and tail ends after a rough rolling step. The specifications include a width range of 1,200 mm to 2,300 mm and a thickness range from 13 mm to 25.4 mm while achieving at least an API standard X65-grade strength. This innovation aids in the unwinding process after being coiled, improving efficiency in steel manufacturing.

Another groundbreaking patent outlines a production equipment line for hot-rolled steel strips. This equipment comprises a rough rolling mill for hot rolling a material heated to a predetermined temperature and a finish rolling mill that controls the rolling to achieve a final sheet thickness. Notably, it features a reversible rolling mill and includes a dual cooling system that optimizes production efficiency.
