SINTERING CONTROL METHOD AND SYSTEM

摘要

A sintering control method and system. The method comprises: detecting a current position of a burn-through point of a sintering trolley operating at a preset speed; determining a relationship between the current position of the burn-through point and a first preset position N and a relationship between the current position of the burn-through point and a second preset position M, [N, M] being an ideal position range of the burn-through point of the sintering trolley; when the current position of the burn-through point is less than N, reducing air quantity of a large flue or reducing a negative pressure of the large flue ; and when the current position of the burn-through point is greater than M, increasing air quantity of the large flue or increasing the negative pressure of the large flue. In the method, the generation of ineffective negative pressure and ineffective air quantity in the sintering process is reduced, and electric power consumed by a main exhaust fan is saved, thereby avoiding adverse effects of the speed regulation of the trolley on the stability of the material flow quality and the control of the follow-up working procedure.
