【正文】 0m/s，如今高線的軋制速度在 80~160m/s。 20 世紀(jì) 70 年代以來(lái)，國(guó)外主要產(chǎn)鋼國(guó)家普遍采用高速線材軋機(jī)和控制冷卻技術(shù)作為線材生產(chǎn)的主要工藝技術(shù)；在冶煉方面．主要是用轉(zhuǎn)爐或電爐初煉，然后采用爐外精煉技術(shù)進(jìn)行二次精煉，同時(shí)基本上是以連 鑄 代替模鑄，而且采用全保護(hù)澆鑄；所以 ， 生產(chǎn)出的線材生產(chǎn)率高、成本低、品種多、質(zhì)量又好。其軋制后可 直接用于鋼筋凝土的配筋和焊接結(jié)構(gòu)件，也可經(jīng)再加工使用。 根據(jù)軋機(jī)的不同可分為高速線材 (高線 )和普通線材 (普線 )兩種。 國(guó)外線材規(guī)格已擴(kuò)大到 Φ50mm。因以盤(pán)條形式交貨，故又通稱(chēng)為盤(pán)條。 關(guān)鍵詞：車(chē)間設(shè)計(jì) 高速線材 線材軋機(jī) 控制軋制 安徽工業(yè)大學(xué)工商學(xué)院 畢業(yè)設(shè)計(jì)（論文）說(shuō)明書(shū) 共 2 頁(yè) 第 2 頁(yè) ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ A workshop of new hot rolled highspeed wire with the output of 630,000 t/a Abstract According to the requirements of graduation design, a new single line of highspeed wire rod workshop with the output of 630,000 t / a will be built. Product specifications are for ~16 mm diameter, each coil weighs about 2 tons. The products in this design include the carbon structural steel and highquality carbon steel. The main contents of the design are mainly as follows, formulation of products scheme and metal balance, design of technological plan and process, the determination of work routine and production capacity analysis of rolling mill, choice of the main equipment, choice and calculation of the auxiliary equipment, the grooves design, the layout of workshop and hoisting and conveying equipment, check of roll strength and motor power, technical and economic indicators of the workshop and environmental protection etc. The continuous casting billet is used as raw materials in this design to reduce the metal loss. The better microstructure of the billets can also improve the quality of the product and reduce the rolling gap time to increase productivity. The reheating furnace is a walking beam type furnace which is side entry and side exit to ensure the tightness of the furnace. The heating capacity is 120t / h. The furnace is controlled by the puter. The exit temperature is 1050~1250176。斯太爾摩冷卻運(yùn)輸系統(tǒng)采用延遲型冷卻運(yùn)輸裝置，它適用于冷卻各類(lèi)碳鋼，具有較好的冷卻效果。 軋機(jī)采用高速線材軋機(jī)，全線均為無(wú)扭軋制 ， 終軋保證速度為 100 m/s，最高軋制速度為 120m/s。加熱爐由微機(jī)控制，出爐溫度為 1050~1250176。 本設(shè)計(jì)原料采用連鑄坯，以減少金屬的 損失 ，而 且連鑄坯的組織結(jié)構(gòu)較好，這也提高了產(chǎn)品的質(zhì)量；還可以減少軋制間隙時(shí)間 ， 提高生產(chǎn)率。本設(shè)計(jì)產(chǎn)品包括碳素結(jié)構(gòu)鋼和優(yōu)質(zhì)碳素鋼。 安徽工業(yè)大學(xué)工商學(xué)院 畢業(yè)設(shè)計(jì)（論文）說(shuō)明書(shū) 共 2 頁(yè) 第 1 頁(yè) ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 畢業(yè)設(shè)計(jì)論文說(shuō)明書(shū) 年產(chǎn) 63萬(wàn)噸熱軋線材車(chē)間設(shè)計(jì) 摘 要 根據(jù)畢業(yè)設(shè)計(jì)的要求，設(shè)計(jì)年產(chǎn) 63 萬(wàn)噸的熱軋高速線材生產(chǎn)車(chē)間， 采用單線軋制方式 。產(chǎn)品規(guī)格為 ~16mm，單卷盤(pán)重約 2 噸。 本車(chē)間設(shè)計(jì)的內(nèi)容主要有：產(chǎn)品大綱和金屬平衡表的制定；設(shè)計(jì)工藝方案和工藝流程；工作制度的確定及軋機(jī)生產(chǎn)能力分析；主要設(shè)備的選擇；輔助設(shè)備的選擇及計(jì)算；車(chē)間平面布置及起重運(yùn)輸；車(chē)間 技術(shù) 經(jīng)濟(jì)指標(biāo)；環(huán)境保護(hù)；孔型設(shè)計(jì)；軋機(jī)力能參數(shù)計(jì)算及電機(jī)設(shè)備校核等。 加熱爐為步進(jìn)梁式加熱爐，進(jìn)出料方式采用側(cè)進(jìn)側(cè)出，以保證爐子的嚴(yán)密性 ， 加熱能力為 120t/h。C。 為改善產(chǎn)品微觀組織，軋后采用控制冷卻技術(shù)，軋后冷卻通過(guò)水冷箱和一套斯太爾摩冷卻運(yùn)輸系統(tǒng)來(lái)完成。 總之，上述先進(jìn) 工藝 技術(shù)和設(shè)備是本設(shè)計(jì)的產(chǎn)品高質(zhì)量的重要保證；同時(shí)也為高線生產(chǎn)車(chē)間設(shè)計(jì)提供了一個(gè)很好的樣板。C.
