什么是高爐煉鐵的還原過程?使用什么還原劑?自然界中沒有天然純鐵,在鐵礦石中鐵與氧結(jié)合在一起,成為氧化物,高爐煉鐵就是要將礦石中的鐵從氧化物中分離出來。鐵氧化物失氧的過程叫還原過程,而用來奪取鐵氧化物中的氧并與氧結(jié)合的物質(zhì)就叫還原劑。凡是與氧結(jié)合能力比鐵與氧結(jié)合能力強(qiáng)的物質(zhì)都可以做還原劑,但從資源和價(jià)格考慮還原劑是CO和H2,C來源于煤,將它干餾成焦炭作為高爐煉鐵的主要燃料,煤磨成粉噴入高爐成為補(bǔ)充燃料。

運(yùn)轉(zhuǎn)環(huán)境的檢查。
⑴PLC運(yùn)轉(zhuǎn)環(huán)境溫度在0~60℃。溫度過高將使得PLC內(nèi)部元件功能惡化和毛病添加,尤其是CPU會(huì)因“電子搬遷”表象的加快而下降PLC的壽數(shù)。溫度偏低,模仿回路的安全系數(shù)也會(huì)變小,超低溫時(shí)能夠致使操控體系動(dòng)作不正常。處置的方法是在操控柜裝置適宜的軸流電扇或許加裝空調(diào),并留意常常檢查。
⑵環(huán)境相對(duì)濕度在5%~95%之間。在濕度較大的環(huán)境中,水分簡(jiǎn)單通過模塊上的IC的金屬表面的缺點(diǎn)侵入內(nèi)部,致使內(nèi)部元件功能的惡化,使內(nèi)部絕緣功能下降,會(huì)因高壓或浪涌電壓而致使短路;在極端枯燥的環(huán)境下,MOS集成電路會(huì)因靜電而致使擊穿。
⑶定時(shí)吹掃內(nèi)部塵埃,以確保風(fēng)道的疏通和元件的絕緣。
⑷檢查PLC的裝置狀態(tài)。各PLC單元固定是不是結(jié)實(shí),各種I/O模塊端子是不是松動(dòng),PLC通訊電纜的子母連接器是不是刺進(jìn)并旋緊,外部連接線有無損害。
⑸檢查PLC的程序存儲(chǔ)器的電池是不是需求替換。
