Abstract

The invention discloses an online judgment method and device for burning consistency in a sintering process and a sintering machine. The method comprises the steps of: detecting the temperature of waste gas after air draft burning of a sintering mixture on a trolley via M temperature detectors and N detection points on each temperature detector to generate an M*N detection temperature matrix, wherein the M temperature detectors are located on a bellows at the middle rear part and distributed uniformly in the running direction of the trolley; performing curve fitting on each column in the M*N detection temperature matrix to generate N columns of temperature curves, wherein the temperature curve is fitted five times by adopting a least square method; generating N sintering end points according to the N columns of temperature curves, and generating an average sintering end point according to the N sintering end points; generating N columns of vertical sintering speeds according to the N sintering end points, and generating an average sintering speed according to the average sintering end point; and generating N corresponding burning consistency indexes according to the N columns of vertical sintering speeds and the average sintering speed.

Description

technical field [0001] The invention belongs to the technical field of sintering production process control, and in particular relates to an online judging method and device of combustion consistency in the sintering process and a sintering machine. Background technique [0002] Sintering production is a process in the field of iron and steel metallurgy, which is to provide high-quality sintered ore for the subsequent blast furnace production process, and the quality of sintered ore will directly affect the blast furnace production process. [0003] During the sintering production process, after the carbon-containing mixture on the trolley is ignited, under the action of the draft, the carbon-containing mixture on the trolley can start to burn from the upper layer down. In this process, in the width direction of the trolley, it will be affected by the edge airflow distribution and the material layer to the west, which will cause a deviation in the downward sintering speed. ...
