專利名稱:鐵合金埋弧爐爐況分析儀的制作方法
技術(shù)領(lǐng)域
本實(shí)用新型涉及一種鐵合金埋弧爐爐況分析儀,屬電子設(shè)備領(lǐng)域。
現(xiàn)有鐵合金埋弧爐操作時(shí)憑經(jīng)驗(yàn)?zāi)繙y(cè),其精度低,不能準(zhǔn)確、及時(shí)地控制爐況,能源消耗大。而且經(jīng)計(jì)算機(jī)聯(lián)機(jī)檢索未見有自動(dòng)測(cè)量鐵合金埋弧爐內(nèi)碳平衡狀況儀器的報(bào)道。
本實(shí)用新型的目的在于提供一種能自動(dòng)并準(zhǔn)確地檢測(cè)、反映鐵合金生產(chǎn)過程中埋弧爐內(nèi)碳平衡爐況的智能鐵合金埋弧爐爐況分析儀。以便及時(shí)、準(zhǔn)確控制爐況、減少能源消耗。
本實(shí)用新型的技術(shù)方案為它由電流信號(hào)傳感器(變壓器)8、碳平衡爐況分析部分、報(bào)警電路部分組成;碳平衡爐況分析部分由A/D轉(zhuǎn)換接口7、公知固態(tài)繼電器接口1、公知的微型計(jì)算機(jī)6、顯示器5、磁盤驅(qū)動(dòng)器4組成,報(bào)警電路由直接與固態(tài)繼電器連接的電鈴3、報(bào)警燈2組成。
電流信號(hào)傳感器(變壓器)8一端連于埋弧爐的3對(duì)石墨電極端9,另一端連于A/D轉(zhuǎn)換接口7輸入端;A/D轉(zhuǎn)換接口7輸出端與微型計(jì)算機(jī)6相連;固態(tài)繼電器接口1輸出端與報(bào)警燈2、電鈴3相連,輸入端與微型計(jì)算機(jī)6相連。
本實(shí)用新型磁盤驅(qū)動(dòng)器4內(nèi)裝有存有爐況分析的軟件的磁盤。
本實(shí)用新型采用軟硬件相結(jié)合的辦法,由電流信號(hào)傳感器從埋爐爐石墨電極端取得信號(hào)并由爐況分析部分實(shí)現(xiàn)頻譜分析并判斷爐況,故具有自動(dòng)化程度高、反映爐況準(zhǔn)確、便于節(jié)約能源、提高經(jīng)濟(jì)效益的優(yōu)點(diǎn),同時(shí)還具有聲光報(bào)警,便于及時(shí)提醒調(diào)整爐況。


圖1為本實(shí)用新型連接框圖。
圖2為本實(shí)用新型A/D轉(zhuǎn)換接口邏輯圖。
圖3為本實(shí)用新型固態(tài)繼電器接口邏輯圖。
以下結(jié)合附圖對(duì)本實(shí)用新型作進(jìn)一步詳述如圖一,鐵合金埋弧爐爐況分析儀由變壓器(電流信號(hào)傳感器)3、碳平衡爐況分析部分、報(bào)警電路部分組成。碳平衡爐況分析部分由A/D轉(zhuǎn)換接口7、固態(tài)繼電器接口1、微型計(jì)算機(jī)6、顯示器5、磁盤驅(qū)動(dòng)器4組成;報(bào)警電路由直接與固態(tài)繼電器連接的一個(gè)電鈴3、7個(gè)報(bào)警燈2(分別指示“電極號(hào)”,“虧碳”,“過碳”,“嚴(yán)重虧碳”,“正?!?,“有問題”,7種爐況)組成。
磁盤驅(qū)動(dòng)器4內(nèi)裝有存有相應(yīng)軟件的磁盤,軟件用BASIC語言和Z-80匯編語言結(jié)合,也可全用Z-80匯編語言。
微型計(jì)算機(jī)采用YEE8100(或TRS80等)。
圖2為A/D轉(zhuǎn)換接口7,其中10為微機(jī)外部數(shù)據(jù)輸入線DI0-DI7,11為AD7574,12為采樣保護(hù)器AD582,13為雙4通道多路模擬開光AD7502,它的輸入來自變壓器8的輸出(只用了3對(duì)輸入端,另一端空著),15為74LS1121為微機(jī)外部地比線A0-A7,20為74LS04;19為地址譯碼器74LS30,18為74L32;22、23分別為微機(jī)外設(shè)控制信號(hào)線SINP和SOUT;24為電解電容,25、26、27、28、29分別為三端穩(wěn)壓器7805、7810、7910、7815、7915、16為微機(jī)的外部數(shù)據(jù)輸入線DI0~DI3。
圖3為固態(tài)繼電器接口1,30為微機(jī)外部數(shù)據(jù)輸入線DO0-D07;31為八D鎖存器74LS373;32為驅(qū)動(dòng)器74LS06,33為3個(gè)JGX-3F型固態(tài)繼電器,其輸出端分別連接指示爐況的7個(gè)指示燈2和一個(gè)報(bào)警電鈴3;40為微機(jī)復(fù)位控制線,35為74LS32;39為微機(jī)輸出地址線A0-A7,36為地址譯碼器74LS30,33為微機(jī)輸出控制線SOUT;37為反相器74LS04,34為三端集成穩(wěn)壓器7805。
使用時(shí),將本爐況分析儀的輸入端(即變壓器8的輸入端)與埋弧爐的三個(gè)石墨電極相連;此時(shí)埋弧爐電弧的一端是石墨電極;另一端是熔融的爐料;當(dāng)爐料中含量增加時(shí),電弧的非線性減少;反之;則電弧的非線性增加;電弧的非線性變化的電流信號(hào)由變壓器8送入爐況分析部分;然后由其對(duì)電極電流信號(hào)進(jìn)行頻譜分析;再根據(jù)波形的非線性程度對(duì)爐況的碳平衡狀況作出判斷,并由固態(tài)繼電器33推動(dòng)電鈴3、指示燈2進(jìn)行聲光報(bào)警;同時(shí);由顯示器5用漢字顯示相應(yīng)的爐況。漢字顯示器及聲光報(bào)警均設(shè)有“正常”、“虧碳”、“過碳”、“嚴(yán)重虧碳”、“嚴(yán)重過碳”、“電極號(hào)”、“有問題”7個(gè)檔次,每個(gè)檔次同時(shí)用漢字顯示調(diào)整爐況的意見,供操作人員參考、操作時(shí),遇到“嚴(yán)重過碳”或“嚴(yán)重虧碳”時(shí);或出現(xiàn)電極硬斷初期時(shí),聲光報(bào)警器同時(shí)報(bào)警,提醒工人及時(shí)處理;防止事故發(fā)生。
對(duì)電極電流信號(hào)的頻譜分析;本可以直接用專用的FFT硬件完成,但FFT芯片價(jià)格昂貴,而爐況變化是一緩慢過程;故采用軟件與硬件相結(jié)合;通過A/D轉(zhuǎn)換接口得到電流信號(hào);再由軟件FFT進(jìn)行頻譜分析。實(shí)踐證明,它完全能滿足實(shí)時(shí)監(jiān)測(cè)。本分析儀的軟件為
