杜邦公司（Dupont）使用Radian激光跟蹤儀在安裝校裝50噸級礦石烘干機
DuPont Co (Dupont) Radian laser tracker used in the installation adjustment of 50 tons ore drying machine
以下是激光跟蹤儀在礦石機械行業(yè)應(yīng)用的典型案例：
The following is a typical case of laser tracker in ore machinery industry application:
在位于田納西州約翰遜維爾的杜邦工廠中，有兩臺將成噸的重礦加熱到4000F（2040C）的50噸級礦石烘干機7*24小運轉(zhuǎn)，因此焦炭和礦石反應(yīng)區(qū)始終非常嘈雜。而且，在該生產(chǎn)階段，該區(qū)域滿是灰塵，并且烘干機周圍布滿了管道、天橋、鋼梁和輥子。工廠生產(chǎn)的最終產(chǎn)品是一種廣泛用于從牙膏到筆記本紙的白色顏料——鈦白粉地（二氧化鈦）。
In Tennessee, Johnson, DuPont plant, two tons of heavy machinery will become heated to 4000F (2040C) 50 tons of ore drying machine 7*24 operation, so the ore and coke reaction zone is always very noisy. Moreover, the area is dusty at the stage of production, and the drier is covered with pipes, bridges, steel beams and rollers. The final product produced by the factory is a white pigment widely used f rom toothpaste to notebook paper - titanium dioxide (titanium dioxide).
在這樣的環(huán)境中，杜邦公司的工人和工程師最近更換了陳舊且使用過度的2號烘干機，并使用了API公司的Radian激光跟蹤儀來確保新烘干機的完美安裝和校準(zhǔn)。聯(lián)系電話186-0138-1355.
In this environment, the DuPont Co of workers and engineers has recently replaced 2 dryer obsolete and excessive use, and the use of laser tracker Radian API company to ensure the perfect installation and calibration of the new drying machine. Contact the phone 186-0138-1355.
“烘干機不僅體積巨大，而且笨重，必須用非常特殊的方法進(jìn)行安裝和定位”來自Rotating Machinery Group（旋轉(zhuǎn)機械組）的杜邦設(shè)備校準(zhǔn)專家Micheal Callan說。新約翰遜維爾工廠在幾個星期前更換了1號焦炭和礦石烘干機，更換時使用傳統(tǒng)光學(xué)器件進(jìn)行測量，用時超過14個小時。Callan相信：“激光跟蹤儀能夠提供更加可靠和精確的測量，對2號機的更換非常有幫助。”
"The dryer is not only huge and bulky, but has to be installed and positioned in a very special way," said Micheal Callan, a DuPont equipment calibration expert f rom Rotating Machinery Group (Rotating Machinery Group). The new Johnson Ville plant changed 1 coke and ore drier a few weeks ago, replacing it with traditional optical devices for more than 14 hours. Callan believes that "laser tracker can provide more reliable and accurate measurement, replacement of the No. 2 machine is very helpful."
“房子是否堅固取決于地基，烘干機容器也是一樣。因此，我們必須使用如Radian激光跟蹤儀這樣的精確設(shè)備，來確保烘干機容器處于正確位置”，Callan說。在更換烘干機時，Callan和其同事旋轉(zhuǎn)機械顧問Mike Burgess必須了解烘干機的位置和傾斜角度。另外，放置輥子的耳軸必須以不同的高度安裝，以確保精確的角度。“我們不能出現(xiàn)絲毫差錯，”Callan說道。
"Whether the house is strong or not depends on the foundation, and the same is the same as the dryer container. Therefore, we must use such as Radian laser tracker that precise equipment, to ensure that the dryer vessel is in the correct position, "said Callan. When changing the dryer, Callan and its colleague rotating machinery consultant Mike Burgess must understand the position and angle of the dryer. In addition, the ear axis of the roller must be installed at different heights to ensure an accurate angle. "We can t make a mistake," Callan said.
“哪怕是三千分之一的英寸的偏移，我們就白忙活了”，Callan補充道。
"Even if it s a 1/3000 inch offset, we re busy," Callan added.
輕型便攜式測量系統(tǒng)（激光跟蹤儀）
Portable measurement system (laser tracker)
Callan從事校準(zhǔn)工作已超過16年，在多年的校準(zhǔn)工作中，他注意到使用激光跟蹤儀將使安裝和操作更加快速、簡單，因此在2012年，他從API公司購買了一臺Radian激光跟蹤儀。他指出：“之所選擇Radian激光跟蹤儀，是因為該型號跟蹤儀的便攜性——與其他跟蹤儀相比，Radian激光跟蹤儀是能實現(xiàn)連續(xù)測量的最輕便的跟蹤儀。”
Callan is engaged in the calibration work has been more than 16 years, in the calibration work for many years, he noticed that the use of laser tracker will enable more rapid and simple installation and operation, so in 2012, he purchased a laser tracker Radian f rom API. He pointed out: "the selected Radian laser tracker, because this type of portable tracker -- compared with other tracker, Radian laser tracker is able to achieve continuous measurement of the most portable tracker."
Callan還喜歡API公司提供的支持與維護。自打購買了Radian激光跟蹤儀，Callan已經(jīng)將其用于諸多測量工作中，其中大多數(shù)是類似于新約翰遜維爾項目的輥子校準(zhǔn)工作。此外，Callan還將該跟蹤儀用于佛羅里達(dá)州的疏浚項目以及其他設(shè)施中絕熱板和設(shè)備絕緣的測量。
Callan also likes the support and maintenance provided by API. Since the purchase of the Radian laser tracker, Callan has been applied to many measurement work, most of them are roller calibration work similar to the new Johnson s project. In addition, Callan will also be used to measure the tracker insulated heat insulating plates and equipment in Florida dredging projects and other facilities.
烘干機內(nèi)外存在巨大壓力
There is great pressure inside and outside the dryer
二氧化鈦量一種亮白色顏料，廣泛用作食用染料以及紙制品和油漆的基礎(chǔ)原料。每年，美國人均二氧化鈦用量達(dá)10磅，其中超過三分之一的二氧化鈦來自田納西州新約翰遜維爾。二氧化鈦的生產(chǎn)過程在距離工廠600英里以外的佛羅里達(dá)沼澤便已開始——在這里提取生產(chǎn)二氧化鈦的煤焦，然后通過駁船將這些黑色粉末狀的焦炭運送到新約約翰遜維爾的杜邦工廠。整個生產(chǎn)過程中，早期工作便是在烘干機中對礦石進(jìn)行高溫高壓處理。
titanium dioxide production, and then transport these black powdered coke to the new DuPont factory in Johnson Ville by barge. In the whole process of production, the early work is to treat the ore at high temperature and high pressure in the dryer.
為了滿足二氧化鈦的需求，杜邦不斷致力于增加生產(chǎn)時間和提高產(chǎn)量，而其中礦石在烘干機中的高溫高壓處理就是一道關(guān)鍵工序。另外，減少停機時間也確保實現(xiàn)生產(chǎn)目標(biāo)的一個主要因素，因此校準(zhǔn)工作必須快速進(jìn)行。
In order to meet the demand of titanium dioxide, DuPont is committed to increasing production time and increasing output, and the high temperature and high pressure treatment of ore in the dryer is a key process. In addition, the reduction of downtime also ensures a major factor in the realization of the production goal, so the calibration must be carried out quickly.
要更換新的烘干機，首先要測量舊烘干機，然后使用起重機將舊的烘干機從原來位置上移除。使用Radian激光跟蹤儀可以在測量舊烘干機的時候?qū)崿F(xiàn)跟蹤測量，并在適當(dāng)位置保留一條虛線作為測量的參考點。此外，Callan在跟蹤儀周圍的四個點安裝了可用作參考的測量靶標(biāo)。在安裝新烘干機后，他能夠通過觀察和測量這些靶標(biāo)來確定新烘干機的安裝位置是否正確。
To replace the new dryer, first measure the old dryer, and then use the crane to remove the old dryer f rom the original position. Using the Radian laser tracker can achieve tracking measurement when measuring the old drying machine, and at the appropriate position to retain a dotted line as the measurement reference point. In addition, Callan at four points around the installation of the tracker can be used as a reference measurement target. After installing the new dryer, he can determine whether the installation position of the new dryer is correct by observing and measuring these targets.
接下來，Callan測量新耳軸的正確位置，得到所有四根輥子的三維坐標(biāo)。
Next, Callan measures the correct position of the new ear axis and gets the three-dimensional coordinates of all four rollers.
兩對耳軸彼此間距43英尺并且高度略有不同，這樣可使烘干機向下傾斜。Callan得出的輥子的距離和角度的測量結(jié)果，隨后工廠工作人員使用尺量法證明了該測量結(jié)果的準(zhǔn)確性。
The two pairs of ear axes are 43 feet apart and slightly different f rom each other, which makes the dryer tilt down. The measurement results of the distance and angle of the roller are obtained by Callan. Then the factory staff use the scale method to prove the accuracy of the measurement results.
挑戰(zhàn)
Challenge
由于支撐結(jié)構(gòu)和管道的妨礙，Callan必須在視線受到阻擋的情況下依靠四個上參考點來確保新烘干機的安裝位置和虛線保持一致。此外，該項工作還需要克服其他復(fù)雜情況，包括：
Due to the hindrance of support structure and pipeline, Callan must rely on four reference points to ensure that the installation position of new dryer is consistent with the dashed line when the line of sight is blocked. In addition, the work needs to overcome other complex situations, including:
附近1烘干機通過鋼梁傳遞的振動，該振動可能會影響測量結(jié)果。
The vibration of a nearby 1 dryer passes through a steel beam, which may affect the measurement results.
輸送熱污水的水管帶來的溫度波動，該溫度變化可能導(dǎo)致鋼梁輕微變形。
The temperature fluctuation caused by the pipe conveying hot water may cause a slight deformation of the steel beam.
參考點的位置可能會過于緊密，甚至可能不在正確位置。
The location of the reference point may be too close and may not even be in the right position.
API激光跟蹤儀工程師隨時提供支持
API laser tracker engineer to provide support at any time
每當(dāng)Callan遇到一個問題，API激光跟蹤儀工程師都能給出答案并在工作過程中進(jìn)行指導(dǎo)。在完成一整天的測量工作后，Callan將測量數(shù)據(jù)記錄在空間分析器中，然后將數(shù)據(jù)電郵給API公司的服務(wù)工程師Will Austin，以確保測量數(shù)據(jù)的準(zhǔn)確性。Austin在查看，能夠重新構(gòu)建Callan的整個測量項目。
When Callan encounters a problem, API laser tracker engineers can give answers and guidance in the work process. After completing the whole day s measurement work, Callan records the measurement data in the spatial analyzer, then sends the data to API Will Austin, to ensure the accuracy of the measurement data. Austin is looking at the entire measurement project that can be rebuilt for Callan.
Austin 在家中與Callan進(jìn)行了一個多小時的通話，他建議Callan在Radian激光跟蹤儀周邊（包括跟蹤儀后面）放置更多的測量靶標(biāo)，以獲得更準(zhǔn)確的讀數(shù)。“你的測量網(wǎng)絡(luò)向外擴展的越大越好，這榜首可以減小誤差”，Austin說。
Austin at home and Callan for more than an hour call, he suggested that Callan in peripheral Radian laser tracker (including tracker behind) placed the measurement target more, to obtain more accurate readings. "The bigger the scale of your measurement network is, the better, the top can reduce the error," Austin said.
由于可以和API工程師分享測量結(jié)果并討論整個項目，Callan充滿自信，并可確保自己的測量結(jié)果是準(zhǔn)確的。
Since you can share the results with API engineers and discuss the whole project, Callan is full of confidence and ensures that the results of their measurements are accurate.
“僅僅通過查看文件，Austin就能找到這些問題，實在是太不可思議了。他給予了我極大的幫助，”Callan說道。
"Just by looking at the file, Austin can find these problems. It s really incredible. He gave me a great deal of help, "Callan said.
盡管測量工作極為復(fù)雜，并且精確度要求很高，Callan和Burgess通過測量數(shù)據(jù)和計算精確地校準(zhǔn)了2號烘干機的安裝位置。然后，使用起重機將2號烘干機按要求放置在準(zhǔn)確位置。完美校準(zhǔn)的烘干機不僅可以減少未來所需要的維護工作，還能延長使用壽命。
Although the measurement is very complex and the accuracy is very high, Callan and Burgess accurately calibrated the installation position of dryer 2 by measuring data and calculation. Then, use the crane to place the No. 2 dryer in the exact position. The perfect calibrated dryer can not only reduce the maintenance work needed in the future, but also prolong the service life.
無論何地，Radian均可以隨身攜帶激光跟蹤儀
No matter where, Radian can carry a laser tracker
自烘干機校準(zhǔn)工作以后，Callan將API公司的Raddian激光跟蹤儀帶到歐洲進(jìn)行了各種各樣的測量工作。他計劃在接下的工作中，使用激光跟蹤儀幫助杜邦工程師在愛荷華移動一個容量達(dá)數(shù)千加侖的儲罐。
Since the calibration of drying machine, Callan laser tracker Raddian API company to Europe measured various jobs. He plans in the next work, using a laser tracker to help DuPont engineer a mobile tank capacity of thousands of gallons in Iowa.
激光跟蹤儀初次應(yīng)用于新設(shè)施測量時，偶爾會讓一些員工吃驚，尤其是那些更加熟悉經(jīng)緯儀或其他光學(xué)方法的老工程師和工作。但Callan相信， Radian跟蹤儀的表現(xiàn)會贏得他們的信任，就像在新約翰遜維爾一樣。
Laser tracker is first applied to the new facilities when measuring, occasionally let some employees surprised, especially those old engineers and more familiar with theodolite or other optical methods. But Callan believes that the Radian tracker will win their trust, as well as in the new Johnson.
“Radian跟蹤儀最終以其出色的表現(xiàn)征服了懷疑者，”他說。
"The final Radian tracker for its outstanding performance to conquer the skeptics," he said.
