Abstract

The invention provides a frequency conversion energy-saving control method for the main exhaust fan of a sintering machine, which includes the following steps: S1: according to the collected temperature, fit the function relationship curve between the temperature of the bellows and the position of the bellows; S2: get the function curve according to the function curve Sintering end point BTP and temperature rise point BRP calculated at time; S3: S3: Determine whether the change of the temperature rise point BRP exceeds the stable range, if not, go to step S4; S4: Calculate according to the sintering end point BTP obtained in step S2 Determine the current vertical sintering speed; calculate and determine the ideal vertical sintering speed with the second-to-last or third-to-last bellows as the sintering end point; S4: Compare the current vertical sintering speed with the ideal vertical sintering speed to determine whether adjustment is required, If adjustment is required, calculate and determine the adjustment value of the corresponding vertical sintering speed; S5: Determine the adjustment value of the speed of the main exhaust fan according to the adjustment value of the vertical sintering speed determined in step S4, and then adjust the speed of the main exhaust fan.

Description

technical field [0001] The invention relates to a sintering production process, in particular to a frequency conversion energy-saving control method for a main exhaust fan of a sintering machine. Background technique [0002] The sintering main exhaust fan of some domestic iron and steel plants adopts frequency conversion speed regulation technology to replace imported valves to adjust the sintering air volume to meet the air volume requirements of the sintering process. [0003] In fact, there are many influencing factors in the sintering production process, such as: ambient temperature, material layer thickness of the trolley, raw material conditions, proportioning conditions, etc., which often lead to large fluctuations in the vertical sintering speed. [0004] However, the current frequency conversion speed control method of the main exhaust fan still adopts open-loop control, that is, it relies on manual experience to judge, operate and adjust, and factors such as the u...
