The invention belongs to the technical field of industrial production, particularly relates to an optimal design method of the length of a main belt of a blast furnace, and solves the problems that the main belt is short, resulting in the reduction of the feeding speed, and too long main belt causes waste of device capacity. The invention proposes the following scheme that a blast furnace feedingsystem furnace top automatic material requiring model for feeding by the main belt, a feeding device and a feeding timing sequence are combined together, departure time of a material requiring signalis set, the length of the main belt and the speed are converted into time TL, to and tzo can be solved according to a maximal batch weight and a device design capacity in the design requirement, and then the self operation time to of a material, the time tzo of feeding the material from a feeding tank to a discharging tank and the time TL are added to obtain material feeding time t, so that the feeding speed K can be obtai
