Embodiment Construction

[0040] based on the following figure 1 , illustrating the best mode of implementation of the present invention.

[0041] Such as figure 1 As shown, it is a schematic structural diagram of using the method of the present invention to perform on-line detection of the burn-through index; it includes: an infrared imaging system 101, an industrial monitor 102, a computer host 103 and a display 104; the infrared imaging system 101 provides two signals at the same time, one A video signal is provided to transmit the actual image of the sinter bed section at the sinter tail to the industrial monitor 102 for on-site operators to directly observe; the other channel provides a digital signal to transmit the digital image of the sinter bed section at the sinter tail to the computer host 103.

[0042] The burn-through index online detection method provided by the present invention comprises the following steps:

[0043] 1. The infrared imaging system 101 scans the image of the sinter bed...

Abstract

The invention is a sintering index on-line detecting method, comprising the following steps of: an infrared imaging system scans the section image of a sinter bed at the end of a sintering machine to obtain an array of dot gray-scale values of a digital image; converting the array into an array of temperature values; judging the upper and lower edges of the sinter bed region and calculating an average height (H) of the whole ore bed; judging the edge of a burning reaction region of the sinter bed and calculating the other average height (h) of a material bed above the burning reaction edge region and the upper edge; calculating then sintering index: Inde=h / h=100%. It quantizes the sintering degree.

Description

technical field [0001] The present invention relates to an on-line detection method of the burn-through index, in particular to a method for judging the end point of the sintering process, that is, the burn-through degree of the tail of the sintering machine, and a method for quantifying the burn-through degree . Background technique [0002] The tail of the sintering machine is the end point of the sintering process. The burn-through degree of the sintered ore deposit at the tail directly reflects whether the running speed of the sintering machine is reasonable, the air permeability of the material layer and the level of fuel ratio. One of the important qualitative indicators of production regulation. For a long time, in order to achieve the continuous stability and high-quality production of sintering production, the method of direct manual observation and observation through the visible light industrial TV system at the tail of the sintering machine is mainly adopted. Th...
