A method and device for determining the degree of damage to grates of a sintering machine trolley

Abstract

The present application discloses a method and device for determining the damage degree of the grate of the sintering machine trolley, wherein the method includes: acquiring an initial image of the grate including the sintering machine trolley; extracting the position of the grate from the initial image The first target image of the region; from the target image, obtain the second target image that contains the target pixels representing the edge of the grate; calculate all the information formed by the target pixels representing the edge of the grate in the second target image The cumulative length of the straight line segment; based on the cumulative length, determine the current damage degree of the grate. Through the embodiment of the present application, the damage degree of the current sintering machine trolley can be directly determined through the cumulative length, and the time when the grate bar reaches any degree of damage can be determined, and further, it solves the problem that the grate bar damage cannot be found in time in the prior art question.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method and device for determining the damage degree of a grate bar of a sintering machine trolley. Background technique [0002] The sintering machine trolley is the key equipment for the sintering process of smelting ore. The important part of the sintering machine trolley is the grate. There are two grate bars, and there is a certain distance between two adjacent grate bars, which are used for drafting and combustion-supporting during the sintering process. [0003] During the sintering process, the grate bars are easily deformed or even fall off under high temperature. If a large number of grate bars are deformed or fall off, the air intake of the sintering machine trolley will be too large, which will affect the output and quality of sinter. [0004] At present, the operator usually infers the condition of the grate bar by observing the sintered ore sintered b...

Problems solved by technology

[0003] During the sintering process, the grate bars are easily deformed or even fall off under the action of high temperature. If a large number of grate bars are deformed or fall off, the air intake of the sintering machine trolley will be too large, which will affect the output and quality of sinter

[0004] At present, the operator usually infers the condition of the grate bar by observing the sintered ore sintered by the sintering machine trolley. However, only when the grate bar has been seriously damaged can the operator infer the damage of the grate bar from the sintered ore, so that the grate bar cannot be found in time. Bar damaged
