中厚板軋機是我國軋鋼生產(chǎn)的主力軋機。中厚鋼板生產(chǎn)線自動化工程系統(tǒng)
是一個包括了軋鋼工藝控制、軋制線區(qū)域控制以及過程控制的復(fù)雜大系統(tǒng)。
本文在介紹了目前國內(nèi)外中厚板生產(chǎn)線自動化工程發(fā)展趨勢后，重點討論
了關(guān)于中厚板生產(chǎn)線自動化工程系統(tǒng)中的工藝控制原理和方法，介紹了相關(guān)的
模型，對大系統(tǒng)的幾種基本結(jié)構(gòu)以及結(jié)構(gòu)的演變作了論述。在此基礎(chǔ)上，提出
了中厚板生產(chǎn)線自動化工程系統(tǒng)的結(jié)構(gòu)模式，最后結(jié)合新余鋼鐵公司厚板廠
3800tnm厚板生產(chǎn)線的自動化系統(tǒng)結(jié)構(gòu)以及系統(tǒng)協(xié)調(diào)功能作了實例分析。
目前，國內(nèi)中厚板生產(chǎn)線自動化系統(tǒng)技術(shù)雖然已經(jīng)取得了很大進步，但是
從整體水平上，與國外同類系統(tǒng)仍然存在一定的差距。本文撰寫的目的就是通
過對比，找出差距，對我國中厚板生產(chǎn)線自動化系統(tǒng)水平盡快達到世界先進水
平作出自己貢獻。
