Description
本發明係有關於一種燒結製程之燃燒速度的量測方法,且特別是一種可量測燒結原料之垂直燃燒速度並判斷其燒透點之發生時間的方法。 The present invention relates to a method for measuring the burning rate of a sintering process, and more particularly to a method for measuring the vertical burning rate of a sintering raw material and determining the occurrence time of the burning point.
燒結製程是將粉鐵礦燒結成塊礦以做為煉鐵原料。請參照第1圖,其係用以說明習知燒結製程的示意圖。首先,根據煉鐵的要求,對包含粉鐵礦、助熔劑以及焦炭的燒結原料進行配料,再將燒結原料置放入台車30中。然後,以燒結機40移動台車30,而台車30之移動路徑的下方設有風箱1-25。台車30在風箱1~2位置,點火罩50對台車30中的燒結原料點火後,便開始進行燒結步驟。當燒結原料表面點火並經過風箱1-25以燒結廢氣風車60抽取台車上方之空氣及進行燃燒反應時,燃燒帶在燒結原料中的位置會隨燒結步驟的進行而逐漸下移,燃燒完之廢氣則經廢氣主管70收集,及靜電集塵器80除塵後排出。燒透點的發生時間是指燒結原料完成燒結的時間,常以燒結原料燒透時所對應之風箱位置來表示。燒結製程之燃燒速度、燒透點的發生時間點對燒結原料成品性質的優劣有重要的影響。燒結原料內的溫度分佈是反應燃燒狀況最具體 的證據,但卻難以直接量測得知。 The sintering process is to sinter the fine iron ore into a lump ore as a raw material for iron making. Please refer to FIG. 1 for illustrating a schematic diagram of a conventional sintering process. First, the sintering raw material containing the fine iron ore, the flux, and the coke is compounded according to the requirements of the iron making, and the sintered raw material is placed in the trolley 30. Then, the trolley 30 is moved by the sintering machine 40, and the bellows 1-25 is provided below the moving path of the trolley 30. The trolley 30 is in the position of the bellows 1 to 2, and after the ignition cover 50 ignites the sintering raw material in the trolley 30, the sintering step is started. When the surface of the sintered raw material is ignited and passes through the bellows 1-25 to extract the air above the trolley and the combustion reaction is performed by the exhaust gas windmill 60, the position of the combustion zone in the sintering raw material gradually moves down as the sintering step progresses, and the combustion is completed. The exhaust gas is collected by the exhaust gas main pipe 70, and the electrostatic precipitator 80 is discharged after being dusted. The occurrence time of the burn-through point refers to the time during which the sintering raw material is sintered, and is often expressed by the position of the bellows corresponding to the sintering of the sintered raw material. The burning speed of the sintering process and the occurrence time of the burning point have an important influence on the quality of the finished product of the sintering raw material. The temperature distribution in the sintered raw material is the most specific reaction combustion condition. Evidence, but it is difficult to measure directly.
習知技術係監測台車經各風箱時處的風箱溫度,再將所量測到之各風箱溫度值以二次曲線法趨近。然後,利用所得之二次方程式來估算燒透點發生的時間點(對應風箱的位置),進而根據燒透點發生的時間點來對現場的配料與燒結製程進行調查。然而,此習知技術僅能估算燒透點發生的時間點(風箱位置),無法得知燒結製程中燒結原料內的燃燒帶移動速度。 The conventional technology monitors the temperature of the bellows at the time of passing through the bellows, and then the temperature values of the measured bellows are approached by the quadratic curve method. Then, the obtained quadratic equation is used to estimate the time point at which the burn-through point occurs (corresponding to the position of the bellows), and then the on-site batching and sintering process is investigated according to the time point at which the burn-through point occurs. However, this prior art can only estimate the time point at which the burn-through point occurs (the position of the bellows), and it is impossible to know the moving speed of the combustion zone in the sintered raw material in the sintering process.
有鑑於此,亟需提供一種可應用於燒結製程中兼具判定燒透點發生的時間點之功能的燃燒速度量測方法。 In view of the above, there is a need to provide a combustion rate measurement method which can be applied to a function of determining a time point at which a burn-through point occurs in a sintering process.

Then, at a plurality of time points in the sintering step, a synchronous detecting step is performed to detect temperature information of one wall of the trolley, and a plurality of temperature profiles of each time point are obtained, wherein each temperature profile is obtained. The relationship between the wall height of the trolley and the wall temperature of the trolley is pointed out, and the synchronous detection step utilizes a non-contact temperature measurement method. Next, look for the high temperature position on the wall corresponding to the relative high temperature value and the relative high temperature value of each temperature profile. Then, a conversion step is performed to convert the above temperature profile into a high temperature position curve for each high temperature position for each time point. Then, a judging step is performed to determine that the high temperature position corresponding to the slope is the position of the sintering material relative to the burning point of the wall surface of the trolley when the absolute value of the slope of the high temperature position curve is less than or equal to the speed threshold value, and the slope is The corresponding time point is the time at which the burn-through point occurs.

請參照第1圖和第2圖,第2圖係繪示本發明之一實施例之燒結製程之燃燒速度的量測方法之流程圖。在本 實施例之量測方法中,首先,提供一燒結步驟200,其中燒結步驟200係對裝載在台車30內之燒結原料進行。在本實施例中,燒結原料可包括例如:粉鐵礦、助熔劑和細焦炭。燒結原料於拌料滾筒混合造粒後,再經由佈料系統放置於燒結機之台車30內。本實施例所使用之燒結機可具有例如:風箱1-25,台車30之壁面32的高度可為例如:60cm,佈料高度可約等同於台車30之壁面32高度。當於風箱1~2點火後,台車30即以例如約2.5~3.3m/min速度向燒結機的尾端移動而開始燒結步驟200。整個燒結步驟200約耗時30分鐘,其中操作條件包括:風箱1-25所量測之壓力值為-1100~-1300mm水柱高,單一風箱流量約為45000m3/h,並經歷風箱1-25抽取含氧空氣及進行燃燒反應。上述燒結步驟200所使用之風箱的數量、台車的規格、燒結原料的配置與點火時間及燒結時間僅係用以舉例說明,本發明之實施例並不在此限。 Referring to FIG. 1 and FIG. 2, FIG. 2 is a flow chart showing a method for measuring the burning speed of a sintering process according to an embodiment of the present invention. In the measuring method of the present embodiment, first, a sintering step 200 is provided in which the sintering step 200 is performed on the sintering raw material loaded in the trolley 30. In the present embodiment, the sintering raw material may include, for example, fine iron ore, a flux, and fine coke. The sintered raw materials are mixed and granulated in a mixing drum, and then placed in a trolley 30 of the sintering machine via a cloth system. The sintering machine used in this embodiment may have, for example, a bellows 1-25, and the height of the wall surface 32 of the trolley 30 may be, for example, 60 cm, and the fabric height may be approximately equal to the height of the wall surface 32 of the trolley 30. When the bellows 1 to 2 are ignited, the carriage 30 is moved to the rear end of the sintering machine at a speed of, for example, about 2.5 to 3.3 m/min to start the sintering step 200. The entire sintering step 200 takes about 30 minutes, wherein the operating conditions include: the pressure value measured by the bellows 1-25 is -1100~-1300 mm water column height, the single bellows flow rate is about 45000 m 3 /h, and the bellows is experienced. 1-25 Extract oxygen-containing air and carry out combustion reaction. The number of bellows used in the above sintering step 200, the specification of the trolley, the arrangement of the sintering raw materials, the ignition timing, and the sintering time are merely illustrative, and the embodiments of the present invention are not limited thereto.
接著,分別於燒結步驟200進行時之複數個時間點,進行一同步偵測步驟210,以偵測台車30之壁面32的溫度資訊,而獲得各時間點之複數個溫度分佈圖。進行同步偵測步驟210的各時間點,可為例如台車30經過各風箱1-25的時間點,或台車30經過其移動路徑上之複數個預設位置的時間點。請參照第3圖,第3圖係繪示根據本發明之一實施例所獲得之於不同時間點之台車30之壁面32的溫度分佈圖,其中此些時間點為台車30經過各風箱(編號)3-25的時間點,每一個溫度分佈圖指出台車30之壁面 32的高度與台車30之壁面32之溫度的關係。以下說明同步偵測步驟210所使用的設備。 Then, at a plurality of time points in the sintering step 200, a synchronization detecting step 210 is performed to detect the temperature information of the wall surface 32 of the trolley 30, and a plurality of temperature distribution maps at each time point are obtained. Each time point of the synchronization detecting step 210 may be, for example, a time point when the trolley 30 passes through each of the wind boxes 1-25, or a time point when the trolley 30 passes a plurality of preset positions on the moving path. Please refer to FIG. 3, which is a temperature distribution diagram of the wall surface 32 of the trolley 30 obtained at different time points according to an embodiment of the present invention, wherein the time points are the trolleys 30 passing through the bellows ( No.) 3-25 time point, each temperature profile indicates the wall of the trolley 30 The relationship between the height of 32 and the temperature of the wall 32 of the trolley 30. The device used in the synchronization detection step 210 will be described below.
由於燒結步驟200中之燒結原料的溫度非常高,導致台車30之壁面32的溫度亦相當高,因此,同步偵測步驟210須使用非接觸式測溫方法。在本實施例中,非接觸式測溫方法係利用一或多個紅外線熱像儀來追縱同一台車30之壁面32的溫度。在進行測溫前,紅外線熱像儀31需先經熱流計對放射率進行校正(修正後的放射率為例如:0.75),再將修正後的放射率與背景溫度輸入,藉以提高紅外線熱像儀測溫的準確性。請參照第4圖,第4圖係本發明之一實施例利用紅外線熱像儀進行同步偵測步驟之配置示意圖。在一實施例中,以一腳架將設置一個紅外線熱像儀31於台車30上,並與台車30之壁面32相隔一距離D(例如:2m),其中此距離D係視待測之壁面32的面積而定。當待測之壁面32的面積愈大,則紅外線熱像儀31離壁面32愈近,即距離D愈小。在另一實施例中,分別設置多個紅外線熱像儀31於台車30的移動路徑上。例如:於每一個風箱25處安裝一個紅外線熱像儀31,並與台車30經過時之壁面32(即移動路徑)相隔一距離D。當紅外線熱像儀31所測得之紅外輻射能量值經由量測時所輸入的環境條件及放射率設定加以修正,並轉變成溫度顯示後,再經由色彩模擬技術將溫度值的分佈以不同顏色顯示,便可將所有的量測點的能量數值轉變成為溫階的影像,如第3圖所示之溫度分佈圖。如第3圖所示,隨著風箱(編號)3-25增加, 代表相對高溫之紅色帶的面積逐漸增加,且向台車30的底部移動。 Since the temperature of the sintering material in the sintering step 200 is very high, the temperature of the wall surface 32 of the trolley 30 is also relatively high. Therefore, the synchronization detecting step 210 must use a non-contact temperature measuring method. In the present embodiment, the non-contact temperature measurement method utilizes one or more infrared cameras to track the temperature of the wall surface 32 of the same vehicle 30. Before the temperature measurement, the infrared camera 31 needs to first correct the emissivity by the heat flow meter (the corrected emissivity is, for example, 0.75), and then input the corrected emissivity and the background temperature to improve the infrared thermal image. The accuracy of the instrument temperature measurement. Referring to FIG. 4, FIG. 4 is a schematic diagram showing the configuration of a synchronization detecting step using an infrared camera according to an embodiment of the present invention. In an embodiment, an infrared camera 31 is disposed on the trolley 30 on a tripod and separated from the wall surface 32 of the trolley 30 by a distance D (for example, 2 m), wherein the distance D is based on the wall to be tested. The area of 32 depends. When the area of the wall surface 32 to be tested is larger, the closer the infrared camera 31 is to the wall surface 32, that is, the smaller the distance D is. In another embodiment, a plurality of infrared cameras 31 are respectively disposed on the moving path of the carriage 30. For example, an infrared camera 31 is mounted at each of the bellows 25, and is separated from the wall surface 32 (i.e., the moving path) when the carriage 30 passes by a distance D. When the infrared radiation energy value measured by the infrared camera 31 is corrected by the environmental conditions and the emissivity settings input during the measurement, and converted into a temperature display, the temperature values are distributed in different colors via a color simulation technique. The display can convert all the energy values of the measurement points into a temperature-graded image, such as the temperature profile shown in Figure 3. As shown in Figure 3, as the bellows (number) 3-25 increases, The area of the red band representing the relatively high temperature gradually increases and moves toward the bottom of the trolley 30.
接著,進行步驟220,以尋找每一張(風箱編號)溫度分佈圖之相對高溫值與相對高溫值所對應之壁面32上的高溫位置。此時,可將每一個風箱編號所對應之相對高溫值與壁面32的高溫位置(壁面高度)整合成一張相對高溫分佈圖,如第5圖所示。如第5圖所示,風箱(編號)3-25漸增可用以表示燒結製程之進行的時間點。隨著燒結製程的進行,相對高溫之紅色帶的面積漸增且向台車30底部移動。此現象代表隨著燒結製程進行,燒結原料溫度呈現由上往下逐步增加的現象。本實施例係藉由數據分析來尋找相對高溫值與高溫位置220。由於從風箱6起才有較明顯之相對高溫值出現,故本實施例可由風箱6開始擷取各溫度分佈圖之相對高溫值與高溫位置。 Next, step 220 is performed to find the high temperature position on the wall 32 corresponding to the relative high temperature value and the relatively high temperature value of each (windbox number) temperature profile. At this time, the relative high temperature value corresponding to each bellows number and the high temperature position (wall height) of the wall surface 32 can be integrated into a relatively high temperature distribution map, as shown in FIG. As shown in Fig. 5, the bellows (number) 3-25 is gradually increased to indicate the point in time at which the sintering process is carried out. As the sintering process progresses, the area of the relatively high temperature red band gradually increases and moves toward the bottom of the trolley 30. This phenomenon represents a phenomenon in which the temperature of the sintering raw material gradually increases from the top to the bottom as the sintering process proceeds. This embodiment seeks a relatively high temperature value and a high temperature position 220 by data analysis. Since the relatively high temperature value occurs from the wind box 6, the present embodiment can start from the wind box 6 to draw the relative high temperature value and high temperature position of each temperature distribution map.
然後,進行轉換步驟230以將各溫度分佈圖轉換為各高溫位置對各時間點之高溫位置曲線,其中時間點是指燒結製程中的時間點。當獲得每一張(風箱編號)溫度分佈圖之相對高溫值與相對高溫值所對應之壁面32上的高溫位置後,便可將這些資料整合成高溫位置對時間點之高溫位置曲線,如第6圖所示。隨著燒結製程進行,相對高溫之紅色帶位於此台車30之壁面32的高度逐漸下移,故形成斜率為負值之高溫位置曲線,其中斜率的絕對值代表燒結步驟的燃燒速度。以本實施例來說,風箱6-17間的燃燒速度是0.02公尺/分鐘,風箱17-20間的燃燒速度是0.038公尺/ 分鐘,而風箱20-24間的燃燒速度是0.003公尺/分鐘。此結果與各個分層間由於透氣性差異造成燃燒速度隨著燒結步驟進行而變動之現象相符。 Then, a conversion step 230 is performed to convert each temperature profile into a high temperature position curve for each high temperature position for each time point, wherein the time point refers to a time point in the sintering process. After obtaining the high temperature position on the wall surface 32 corresponding to the relative high temperature value and the relative high temperature value of each (windbox number) temperature profile, the data can be integrated into a high temperature position curve of the high temperature position to the time point, such as Figure 6 shows. As the sintering process proceeds, the relatively high temperature red band is gradually lowered in the height of the wall surface 32 of the carriage 30, so that a high temperature position curve having a negative slope is formed, wherein the absolute value of the slope represents the burning speed of the sintering step. In the present embodiment, the burning speed between the bellows 6-17 is 0.02 m/min, and the burning speed between the bellows 17-20 is 0.038 m/ Minutes, while the burning speed between the bellows 20-24 is 0.003 meters / minute. This result is consistent with the phenomenon that the burning speed varies with the progress of the sintering step due to the difference in gas permeability between the respective layers.
然後,進行判斷步驟240,以在高溫位置曲線之斜率的絕對值小於或等於速度門檻值時,判斷此斜率所對應之高溫位置為燒結原料相對台車之壁面之燒透點的位置,而此斜率所對應之時間點則為燒透點的發生時間。在本實施例中,速度門檻值為0.003公尺/分鐘。換言之,高溫位置曲線之斜率之絕對值為等於或小於0.003公尺/分鐘時,此斜率所對應之高溫位置為燒結原料相對台車30之壁面32之燒透點A的位置,而此斜率所對應之時間點則為燒透點A的發生時間(風箱24),此推測之燒透點的發生時間與肉眼判定之結果相同。 Then, a determining step 240 is performed to determine that the high temperature position corresponding to the slope is the position of the sintering material relative to the burning point of the wall surface of the trolley when the absolute value of the slope of the high temperature position curve is less than or equal to the speed threshold value, and the slope The corresponding time point is the time of occurrence of the burn-through point. In this embodiment, the speed threshold is 0.003 meters/minute. In other words, when the absolute value of the slope of the high temperature position curve is equal to or less than 0.003 m/min, the high temperature position corresponding to the slope is the position of the sintering material relative to the burning point A of the wall surface 32 of the trolley 30, and the slope corresponds to The time point is the time at which the burn-through point A occurs (the bellows 24), and the estimated burn-through point occurs at the same time as the result of the naked eye determination.
由上述本發明之實施方式可知,本發明之優點為:可自動地推測出燒透點的發生時間;可避免因經驗不足造成燒透點的發生時間有誤判之疑慮;可在不影響燒結製程之狀況下量測燃燒速度並判斷燒透點的發生時間;可獲得燃燒速度與燒透點的發生時間之數據,以調整後續製程條件之,而增加產量、提升品質並降低經濟成本。 It can be seen from the above embodiments of the present invention that the invention has the advantages that the occurrence time of the burn-through point can be automatically estimated; the doubt that the occurrence time of the burn-through point is misjudged due to lack of experience can be avoided; the sintering process can be not affected Under the condition, the burning speed is measured and the occurrence time of the burning point is determined; the data of the burning speed and the burning time of the burning point can be obtained to adjust the subsequent processing conditions, thereby increasing the output, improving the quality and reducing the economic cost.
