隨著冶煉技術(shù)的發(fā)展,國(guó)際爐料結(jié)構(gòu)發(fā)生了較大變化,歐美等大多數(shù)國(guó)家在爐料上增加球團(tuán)礦使用比例,許多使用比例達(dá)到50%以上,甚至還有采用全球團(tuán)爐料方案的。他們認(rèn)為關(guān)閉燒結(jié)廠不但有利于環(huán)保,而且發(fā)現(xiàn)用球團(tuán)礦有利于降低鐵前成本。因此,增加球因使用量,可使高爐技術(shù)指標(biāo)、能耗指標(biāo)、經(jīng)濟(jì)指標(biāo)都得到較大的改善。
二、解決方案:
在本項(xiàng)目中，我們采用德國(guó)西門(mén)子公司的PLC、通訊、工控軟件及傳動(dòng)控制產(chǎn)品組成高質(zhì)量、高性能的整合的控制系統(tǒng)，完成整個(gè)項(xiàng)目的過(guò)程及拖動(dòng)控制任務(wù)。其中，采用了兩套S7-300型PLC、二十多套MASTERDRIVER系列傳動(dòng)產(chǎn)品（功率范圍從幾KW到數(shù)百KW）。
上位監(jiān)控系統(tǒng)由工業(yè)控制計(jì)算機(jī)配裝工控軟件，完成整個(gè)系統(tǒng)的過(guò)程數(shù)據(jù)采集、運(yùn)行狀態(tài)監(jiān)視、系統(tǒng)設(shè)備控制及其他工業(yè)數(shù)據(jù)的采集、報(bào)表生成、打印、數(shù)據(jù)備份等工作。PLC系統(tǒng)與傳動(dòng)控制系統(tǒng)間采用的是西門(mén)子公司的PROFIBUS-DP總線通訊方式，完成控制信號(hào)及數(shù)據(jù)的高速傳遞與交換。同時(shí)，各子系統(tǒng)PLC與該子系統(tǒng)設(shè)備間有充分的信號(hào)線連接，當(dāng)通訊系統(tǒng)出現(xiàn)故障時(shí)，子系統(tǒng)可獨(dú)立運(yùn)行，保證系統(tǒng)的安全性及可靠性。
