For coke, coal with caking properties is charged into the carbonization chamber of the coke oven through a plurality of charging holes using a charging car at the hearth of the coke oven, and then indirectly heated to a set temperature while the coke oven is sealed and carbonized for a set time. is produced

At this time, the finished red hot coke is extruded out of the coke oven by the extruder.

Then, the door provided in the carbonization chamber of the coke oven is detached. At this time, the door frame and the buckstay, which are adjacent steel structures, are directly exposed to high temperature due to the high-temperature refractory material and radiant heat of the coke. do.

Among these structures, the buckstay is an H-shaped steel structure that maintains structural robustness in the coke oven. When exposed to high temperatures, the shape of the buckstay is distorted and deformed due to the difference in the coefficient of thermal expansion between the portion exposed to heat and the portion not exposed to heat. etc. occurs.

In addition, as the degree of deformation of the door frame increases, the airtightness between the door and the door frame is weakened, so that gas generated during coke production is released into the gap of the door.

Since a cooling unit (not shown) is installed in the housing 400 , cooling air may be supplied into the housing 400 to cool the interior of the housing 400 to a set temperature or less.

In addition, since the transparent part 420 is installed on one surface of the housing 400, the distance measuring part 100 and the temperature measuring part 200 do not interfere with the movement path of the signal (laser, etc.) for measuring the distance and temperature. won't

Since the injection nozzle 430 is installed on the outside of the housing 400 , it is possible to prevent the transparent part 420 from being contaminated by dust by spraying a gas such as air to the transparent part 420 .

The process of measuring the degree of strain will be described in more detail as follows.

That is, since the door of the carbonization chamber 11 is opened during the extruding time of the red hot coke from the carbonization chamber 11, the temperature of the buckstay 30 rises due to the carbonization chamber 11 and radiant heat of the coke.

In particular, among the surfaces of the buckstay 30 , the inner surface adjacent to the carbonization chamber 11 has a greater temperature rise than the outer surface away from the carbonization chamber 11 .

Since a general material has a property of expanding as the temperature rises, each surface of the buckstay 30 expands according to the coefficient of hot linear expansion.

However, the inner surface of the buckstay 30 expands longer than the outer surface because the increase in temperature is greater than that of the outer surface.

Accordingly, during the extrusion time of the red hot coke, the deformation degree of the inner surface of the buckstay is greater than that of the outer surface.

The distance measuring unit 100 and the temperature measuring unit 200 are measured by the image measuring sensor 330 after the extruder 20 is stopped in front of the carbonization chamber 11 so as to measure the change in the degree of deformation. Measurement data may be collected from after the recognition of the serial number of the buckstay 30 is finished until the extruder 20 moves for the next operation.

4 is a graph of data indicating distances measured for each measurement time by each distance measuring unit.

The distance measuring unit 100 is configured not to be affected by radiant heat generated from the carbonization chamber 11 by measuring at a distance more than a set distance from the buckstay 30, and is located inside the housing 400 in order to prepare for an emergency situation. installed.

The distance measuring unit 100 measures the distance to the upper part, the middle part, and the lower part of the buckstay 30 and transmits it to the information receiving unit 310 , and the information receiving unit 310 converts this information to the deformation degree calculation and storage unit 320 . ) to be transmitted and stored.

The laser distance measurers 110, 120, and 130 of the distance measuring unit 100 located in the upper, middle, and lower portions of the extruder 20, respectively, are spring portions present at the top of the buckstay 30, carbonization chamber 11, respectively. At the midpoint of the ceiling and the floor, the carbonization chamber 11 is provided to correspond to the bottom portion, respectively.

As the distance value measured by the distance measuring unit 100 increases, the buckstay 30 is a value located toward the carbonization chamber 11, and the shorter the distance value measured by the distance measuring unit 100, the more it protrudes toward the extruder 20. value is located.

It is possible to evaluate how much the buckstay 30 protrudes from this measurement data.

In order to check how much the buckstay 30 is deformed from the measured data, the degree of deformation of the buckstay 30 may be defined as a difference value between the maximum value and the minimum value of the measured distance value.

Structural robustness can be maintained only when the buckstay 30 stands vertically from the installation surface without deformation.

However, if the buckstay 30 is tilted away from the vertical from the installation surface, the force supporting the structure is weakened, and accordingly, the structure of the buckstay 30 may be damaged, so The degree of strain that can obtain the degree of deviation from the vertical is defined.

When the difference between the maximum value and the minimum value of the distance value measured by the distance measurement unit 100 is deformed by more than the set length, the structural support force of the buckstay 30 is weakened. The value minus the minimum value was used.

It can be defined using the average value of the derived strain values over the entire measurement time. For more accurate deformation measurement, three or more transaction measurement units may be located, and the same logic for deriving the deformation degree may be used.

5 is a graph showing the degree of deformation of the buckstay, and a set length, for example, a location showing a degree of deformation of about 40 mm or more, is included.

When the degree of deformation greater than the set length is shown, the structural stability of the buckstay 30 is lowered, and since the binding force to the refractory material present in the adjacent carbonization chamber 11 is weakened, the bolts present for adjusting the buckstay 30 And by adjusting the spring, it is possible to perform an operation of reducing the deviation of the upper, middle, and lower measurement distances.

In addition, a method of controlling the temperature of the buckstay 30 after measuring the temperature of the buckstay 30 using the temperature measuring unit according to the present invention as shown in FIGS. 6 and 7 may be used.

That is, FIG. 6 is a graph of a location where the temperature deviation of the buckstay 30 is relatively large as a result of temperature measurement by the temperature measurement unit 200 , and FIG. 7 is a temperature measurement result of the buckstay 30 by the temperature measurement unit 200 . ) is a graph for a location with a relatively small temperature deviation.

As shown in FIG. 6 , when the temperature deviation of the buckstay 30 is large, the radiant heat from the carbonization chamber 11 is relatively high, and the inner surface of the buckstay 30 that exists close from the carbonization chamber 11 . is the case when the temperature of

In the case of such a carbonization chamber, structural stability of the structure of the buckstay 30 can be controlled through a method of controlling the temperature of the combustion chamber 13 by determining that the temperature of the inlet side is maintained excessively high.

As such, by immediately performing repair work during coke extrusion in the carbonization chamber 11, a value with a reduced degree of deformation of the buckstay 30 can be obtained in the next measurement, and the coke oven can be managed through real-time distance and temperature measurement values. can

In addition, the value of the deformation degree is stored for every extrusion of the carbonization chamber 11, and the change in the deformation degree according to the operation history can be analyzed by comparing it with the existing value, and accordingly, the deformation degree of the buckstay exceeds the limit value. There is also the effect that preventive maintenance is possible in advance.
