Embodiment Construction

[0040] As mentioned in the background technology, at present, in the sintering production of enterprises, it is often controlled by manual experience. Watching the section of the tailings layer from the scene or online video, there is no flame coming out, and the upper black and lower red ore layers account for about 2 / 3 and 1 / 3 respectively. 3. It can be judged that the end point is normal; if the black layer becomes thicker and the red ore layer becomes thinner, it can be judged that the end point is advanced; if there are flames at the lower edge of the red layer, and there are unburnt raw materials, it can be judged that the end point is delayed. If the end point is found to be early, the speed of the machine should be increased; if the end point is lagging behind, the speed of the machine should be slowed down; when the air permeability has changed greatly and it is difficult to control the end point only by adjusting the speed of the machine, the thickness of the material ...

Abstract

The invention discloses a sintering system and a sintering endpoint control method of the sintering system. The control method comprises the steps of collecting the temperature values of multiple sintering bellows adjacent in sequence, setting a sintering temperature function according to the distances between the multiple sintering bellows adjacent in sequence and a sintering head and the temperature values, determining the highest temperature turning point according to the sintering temperature function, and judging whether the sintering endpoint is normal or not according to the highest temperature turning point. The control method can automatically judge whether the sintering endpoint is normal or not, working efficiency is high, and judgment is accurate. The sintering system based on the control method can automatically judge whether the sintering endpoint is normal or not by the adoption of a temperature collection device and an industrial host.

Description

technical field [0001] The invention relates to the technical field of sintering process control, more specifically, to a sintering system and a method for controlling the sintering end point. Background technique [0002] Sintering is to spread the mixture from the distributor to the trolley of the sintering table and ignite it. The exhaust fan draws in air from top to bottom, and burns the fuel in the mixture layer. The sintered ore is fired continuously from top to bottom. , cooled, granulated and then sent to the blast furnace, and the ore is returned under the sieve and mixed with the mixture for re-sintering. [0003] Controlling the sintering end point is to control the position of the trolley on the sintering table when the sintering process is completed. The end point of small and medium-sized sintering machines is generally controlled at the position of the penultimate bellows, and the end point of large sintering machines is generally controlled at On the penulti...
