The invention discloses a design method of an automatic hot-rolled strip steel quality grading management system. The design method comprises the following steps: performing classified statistics on a quality hit rate condition and manually input process quality information according to process actual performance data, and evaluating a process quality grade of a quality dimension according to a process quality evaluation standard; evaluating the dimension quality grade of the quality dimension according to a dimension quality evaluation standard by using the process quality grade result of the quality dimension; and performing comprehensive quality evaluation according to the dimension quality grade of the quality dimension and a comprehensive quality evaluation standard to realize quality management. According to the invention, visual grading evaluation and automatic monitoring are carried out from five mass dimensions of the steel coil; the conversion from process basic data to a steel coil quality result i
