PLC控制系統(tǒng)的配置
1.1 工藝流程簡(jiǎn)介
鑄管退火爐是一個(gè)長(zhǎng)54m退火爐，根據(jù)水冷離心球墨鑄鐵管的熱處理工藝，爐體設(shè)計(jì)為四段，分別為：加熱段、保溫段、速冷段和緩冷段。加熱段和保溫段兩側(cè)爐墻采用低水泥澆注料整體澆注，速冷段和緩冷段兩側(cè)爐墻采用粘土磚砌筑，爐頂全部采用耐火纖維爐襯。退火爐各爐段參數(shù)如圖1所示。
退火爐為熱管入爐，要將其加熱段升溫至960℃，如圖1所示。退火工藝曲線上各點(diǎn)溫度指的是鑄管溫度、而不是爐溫，因此鑄管溫度的測(cè)量及控制是至關(guān)重要的，尤其是速冷段末管壁溫度控制要求較嚴(yán)。
1.2 PLC系統(tǒng)硬件配置
