3.1 真空室真空度測(cè)量變送器是一塊很關(guān)鍵的檢測(cè)儀表。目前國(guó)內(nèi)能夠檢定或校準(zhǔn)真空度變送器的機(jī)構(gòu)很少。但是真空度數(shù)值的準(zhǔn)確與否與品種鋼的冶煉至關(guān)重要。真空度變送器往檢定機(jī)構(gòu)送檢來(lái)回至少需要10天的時(shí)間,這是快節(jié)奏的生產(chǎn)工藝不允許的。為此,一般在設(shè)備投產(chǎn)前,訂購(gòu)型號(hào)規(guī)格一樣的備件,一旦懷疑真空度測(cè)量失準(zhǔn),往往用替換的方法解決,而把換下來(lái)的變送器送外檢定,這樣一來(lái),既不影響生產(chǎn)正常進(jìn)行,也能通過(guò)檢定變送器找出影響生產(chǎn)的真正原因。
3.2關(guān)于配料秤的校準(zhǔn)問(wèn)題。RH爐配料秤比高爐、轉(zhuǎn)爐配料秤的準(zhǔn)確度要求高。因此,校秤方法和設(shè)備就很重要。以前我們用測(cè)力環(huán)校秤,但是誤差較大。后又采用實(shí)物法校秤,即通過(guò)實(shí)際向料斗輸入的物料再排放到汽車斗內(nèi),然后汽車卸料,用高精度臺(tái)秤對(duì)卸下的料分批過(guò)秤。此方法準(zhǔn)確度很高,但是勞動(dòng)量太大,耗時(shí)較長(zhǎng),對(duì)正常生產(chǎn)節(jié)奏有影響,F(xiàn)在,我們改用稱重測(cè)力儀對(duì)料斗秤進(jìn)行校秤,此測(cè)力儀自帶稱重傳感器,自帶重量顯示,檢定方便。用它校秤,RH爐料斗秤的準(zhǔn)確度完全能夠滿足生產(chǎn)品種鋼的需要,克服了上述兩種校秤方法的缺點(diǎn)。
3.3 Quantum 雙機(jī)熱備結(jié)構(gòu)中采用的以太網(wǎng)模板是140NOE77101, 在進(jìn)行熱備切換時(shí), 以太網(wǎng)通訊故障, 這是因?yàn)?40NOE77101應(yīng)用于雙機(jī)熱備結(jié)構(gòu)中時(shí), 要求它的Firmware版本號(hào)必須大于2.0,否則當(dāng)發(fā)生熱備切換時(shí), 以太網(wǎng)通訊將出現(xiàn)異常, 但以太網(wǎng)模板140NOE77100卻無(wú)此問(wèn)題, 解決的辦法是更新140NOE77101硬件 Firmware版本號(hào)。
3.4 安裝中要注意,Quantum 的 RIO電纜系統(tǒng)中對(duì)分站電纜的長(zhǎng)度是有要求的, 所允許的最小長(zhǎng)度為2.5m , 如果小于2.5m 就會(huì)產(chǎn)生分支器反射, 會(huì)在 RIO 分站適配器中產(chǎn)生誤差。
3.5 調(diào)試中我們?cè)鴩L試同時(shí)連接Quantum的140NOE771xx上的兩個(gè)端口,想分別從中接收數(shù)據(jù),但是沒(méi)有成功。經(jīng)咨詢廠家技術(shù)支持,得知140NOE771xx是一個(gè)單通道的設(shè)備,兩個(gè)端口不能在同一時(shí)
3.6 一次檢修后,恢復(fù)送電發(fā)現(xiàn)Quantum以太網(wǎng)模板140NOE771X0上Appl燈亮,采用了很多方法也不能使之熄滅。后經(jīng)咨詢工程師了解到,NOE模板如果發(fā)生過(guò)系統(tǒng)崩潰,就會(huì)在模板內(nèi)部創(chuàng)建一個(gè)記錄文件,并且NOE模板上的Appl燈亮。要想使之熄滅,需要通過(guò)IE瀏覽器進(jìn)入NOE模板,進(jìn)入NOE Diagnostics,再進(jìn)入Crash Log File Diagnostics,查找到崩潰信息,點(diǎn)擊“Clear Crash Log File”,就可以清除這些崩潰信息,Appl燈也會(huì)熄滅。
