Field of the Invention The present invention relates generally to prolonging the life of a coke oven furnace body, and more particularly to a method for collecting, managing, and analyzing enormous amounts of information relating to the coke oven furnace body and providing appropriate repair guidelines. .

Description of the Related Art The life of a coke oven is the time when the internal brick deteriorates over time and is damaged due to the history of past operations, and the coke cannot be taken out of the oven, generally 30 to 35 years. It is said. At the end of the service life, poor carbonization of coal, clogging of kilns, etc. not only adversely affect coke production, but also adversely affect the environment such as gas leakage and black smoke due to brick breakage.

ていた。Since the coke oven is a continuous operation facility,
The operation cannot be stopped and cooled after the construction starts. Further, due to the structure in which bricks are precisely stacked, it is extremely difficult to renew the inner brick. For this reason, currently, life extension measures such as spraying the damaged part inside the kiln are being taken. However, a coke oven in a general steel mill has about 300 to 400 kilns in which a carbonization chamber (hereinafter referred to as a kiln) and a combustion chamber are paired. Conventionally, since there was no suitable means for evaluating deterioration, the kiln to be repaired was judged by visually observing the kiln with remarkable deterioration and repairing.

れる技術がある。In recent years, various qualitative and quantitative diagnostic methods for the deterioration condition of each kiln of a coke oven have been proposed. For example, Japanese Unexamined Patent Application Publication No. Hei 3-
As a technique disclosed in Japanese Patent Laid-Open No. 146589 and a technique using an image analysis technique, there is a technique disclosed in Japanese Patent Laid-Open No. 3-105195.

流値をピーク、斜線部の面積をエリアと称する。This internal extrusion current data is the motor current value for the extruder ram drive of the extruder when coal is carbonized in the coke oven to form coke and is discharged to the outside of the coke oven. This is the data measured each time the kiln is taken out. FIG. 4 shows the extrusion current data measured when one kiln was taken out once. The extrusion current value at point A is called the peak, and the area of the shaded area is called the area.

によって窯毎の劣化程度の判定ができる。The degree of deterioration can be determined based on the dust concentration. When there is a gap in the brick on the furnace wall, when the coke is pushed out and the furnace pressure becomes negative, unburned gas from the combustion chamber enters the carbonization chamber, and soot is generated. If the concentration of soot and dust is measured with a gas recovery pipe that connects each kiln, the degree of penetration of unburned gas in each kiln can be measured. The peak value of this dust concentration is taken as the value showing the deterioration characteristics of the kiln during the extrusion. This makes it possible to determine the degree of deterioration for each kiln.

な補修を行なうことが必要である。The prior art relates to a method for diagnosing and repairing individual kilns, and enables quantitative evaluation of specific kilns, but manages deterioration tendency, furnace groups or coke. There was a problem that the evaluation within the entire furnace, that is, the priority of the kiln to be repaired, etc. was unclear, and repair guidance and repair guidelines could not be determined. In order to achieve the optimal life extension, it is necessary to effectively utilize individual diagnostic data and perform effective repairs.

とにある。However, the coke oven has a large number of kilns as described above, and the amount of information is enormous when including operation information and furnace operation information that affect the deterioration of the kiln, not to mention diagnostic information and repair information. It will be a large amount, resulting in insufficient management of information. In addition, the judgment of the carbonization chamber to be repaired, which is performed by multiple deterioration evaluations, tends to vary from person to person, and the kiln to be originally repaired may be erroneously determined, or the deterioration may become particularly severe, which may lead to production problems. The cost and environment will be different. The problem to be solved by the present invention is to effectively utilize individual diagnostic techniques and to carry out effective repair ordering in order to carry out an optimal coke oven life prolonging measure.

当が遅れた場合には、壁の一部が脱落してその窯の閉鎖
に繋がり、閉鎖する窯が増大して操業能率が低下する。The function of the brick of the coke oven body can be classified into wear deterioration and cracking deterioration. Deterioration of the abrasion property means that the brick on the carbonization chamber side is worn out with a certain spread. Abrasion deterioration has a strong correlation with image analysis data and extrusion current characteristics (peak, area), but has almost no effect on dust concentration. When the allowance for the abrasion damage of bricks is delayed, a part of the wall falls off, which leads to the closure of the kiln, and the number of kilns to be closed increases and the operating efficiency decreases.

まねく。On the other hand, the deterioration of the cracking property is caused by the fact that the joints of bricks have fallen off, and can be appropriately measured by the dust concentration and the furnace width meter. When the cracking property deteriorates, the gas leaked from the cracking portion may exceed the capacity of the dust collector and cause an environmental problem of generating black smoke. In addition, deterioration of wear resistance and deterioration of cracking property both reduce heat transfer in the deteriorated portion, leading to deterioration of coke quality.

環境への影響程度を示す値が得られる。In each measurement method, sensitivity to wear deterioration and crack deterioration can be set according to the characteristics. Of these,
By weighting each measured value using the number corresponding to the sensitivity of cracking deterioration as an environmental impact index, a value indicating the degree of environmental impact that is obtained by integrating a plurality of measurement results can be obtained.

From the results, a value indicating the degree of influence on coke quality or operating efficiency can be obtained.

From these results, it is possible to judge the kiln with a remarkable deterioration tendency and the kiln with the most deterioration due to each of the extrusion current, the image analysis data, and the dust concentration, and it can be used as repair guidance.

Classify as missing. First, as shown in Table 5, the characteristics of extrusion current, image analysis, and dust concentration are qualitatively evaluated by ⊚, ◯, Δ, and × in the order in which the deterioration phenomenon can be measured. Further, a score is given for each of these symbols as shown in Table 6.

係数を決める。On the other hand, the extent to which the deterioration phenomenon of surface defects, cracks, cracks and defects affects the environment is quantified as shown in Table 7. Since surface flaws do not directly affect the generation of soot and dust, they have a low value, and the influence on soot and dust generation increases in the order of cracks, cracks, and defects. Therefore, a large influence coefficient is set in that order. Similarly, for coke quality and equipment efficiency, influence coefficients are determined for each deterioration phenomenon.

５ｘ０．２＝６．７５となる。By connecting Table 5, Table 6 and Table 7, the environmental influence index, the quality influence index and the efficiency influence index are determined according to the characteristics of the extrusion current, the image analysis and the dust concentration.
Specifically, the symbols in Table 5 are replaced by the scores in Table 6, and the values obtained by multiplying the symbols in Table 6 by the environmental impact coefficients in Table 7 are used as the environmental impact index of the measurement method. For example, the environmental index of the peak of extrusion current is 100x0 + 5x0.5 + 5x0.3 + 2.
5 × 0.2 = 6.75.

補修をすべきかが、個人差なく客観的に求められる。Each characteristic value obtained for each kiln is normalized by an appropriate standard. For example, the peak of the extrusion current is normalized with the maximum allowable instantaneous electric current of the electric motor being 100, and the increment is normalized with an increase of 10% per 10 days being 100. For a certain kiln, the normalized peak value of extrusion current is multiplied by the environmental influence coefficient of the above-mentioned extrusion current, and the normalized image analysis value is also multiplied by the environmental influence coefficient of the above-mentioned image analysis to obtain the normalized soot dust. The value obtained by summing the values obtained by multiplying the concentration by the environmental impact coefficient of the dust concentration is the value that represents the degree of deterioration in terms of the environmental impact of the kiln. If this is obtained for all kilns, the more severely deteriorated the kiln will be, the larger the value will be, and which kiln should be repaired can be objectively determined without individual differences.
