【正文】 1 / 69摘 要根據(jù)設(shè)計要求擬建一個優(yōu)碳年產(chǎn) 80 萬噸的高速線材生產(chǎn)車間。它的最高軋制速度為 110m/s，產(chǎn)品規(guī)格為 ~φ12mm，盤卷單重約 2 噸。連鑄坯在步進梁式加熱爐中使用煤氣加熱，側(cè)進側(cè)出，加熱能力為75t/h。加熱爐由微機控制，出爐溫度為 900℃～1050℃。該套軋機采用全連軋無扭工藝，連鑄坯為 150150mm，長約為 12m，單重約為 的方坯。在 13 架平立交替布置的粗軋機和中軋機之后，布置了 2 架預(yù)精軋機，13 架精軋機。軋后冷卻通過水冷箱和一套斯太爾摩冷卻運輸線（120m）來完成。該套斯太爾摩冷卻運輸系統(tǒng)采用延遲型冷卻裝置，可對成品軋材的最終性能控制如抗拉強度及產(chǎn)品的金相組織和氧化鐵皮厚度進行最終控制。計算機系統(tǒng)用于控軋和控冷，無張力軋制，最佳剪切尺寸控制和缺陷檢測。關(guān)鍵詞 ： 高速線材；生產(chǎn)方案；孔型設(shè)計；校核2 /

論線材制品的品種與質(zhì)量，不僅決定于其本身的生產(chǎn)工藝技術(shù)與裝備水平，而且在很大程度上更有賴于其原料——線材的冶煉與軋制技術(shù)。也就是說，線材品種質(zhì)量的提高，將大大促進線材制品行業(yè)的發(fā)展與進步，否則線材制品行業(yè)的發(fā)展將受到制約，甚至處于落后狀態(tài)。這是 100 多年來線材制品行業(yè)發(fā)展歷史所證實的．因此線材與其制品的關(guān)系是密不可分的。線材一般是指直徑為 5——16mm 的熱軋圓鋼或相當(dāng)該斷面的異型鋼，因以盤卷狀態(tài)交貨，統(tǒng)稱為線材或盤條。國外線材規(guī)格已擴大到約 。常見線材多為圓斷面，異型斷面線材有橢圓形、方形及螺紋形等，但生產(chǎn)數(shù)都很少。
