在現(xiàn)代社會(huì)的國(guó)民生產(chǎn)中，由于鋼鐵材料的用途十分廣泛，不論農(nóng)業(yè)、工業(yè)、國(guó)防建設(shè)，都需要 有質(zhì)量?jī)?yōu)良，品種齊全，數(shù)量足夠的鋼鐵，因此鋼鐵工業(yè)的發(fā)展有著非常重要的意義。 設(shè)計(jì)附有車(chē)間平面圖、孔型圖及配輥圖。 設(shè)計(jì)采用全線無(wú)扭連軋方式。但 合金 鋼熱塑性差，加工性能差，軋制變形要求減少道次壓下。河北 聯(lián)合 大學(xué)輕工學(xué)院 QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY 畢業(yè)設(shè)計(jì)說(shuō)明書(shū) 設(shè)計(jì)（論文）題目： 年產(chǎn) 65

棒材在機(jī)械軸類(lèi)零件中有廣泛的應(yīng)用，在軋制加工的基礎(chǔ)上，熱處理性能極為優(yōu)良，可以經(jīng)過(guò)淬火，達(dá)到相當(dāng)高的強(qiáng)度和韌性。 根據(jù)任務(wù)書(shū)要求，設(shè)計(jì)年產(chǎn) 65萬(wàn)噸 棒材廠。平立交替的連軋棒材方式事故少，生產(chǎn)效率高，產(chǎn)量大。 關(guān)鍵詞： 車(chē)間設(shè)計(jì)；棒材 生產(chǎn) ； 孔型設(shè)計(jì)；高精度 河北聯(lián)合大學(xué)輕工學(xué)院 II Abstract According to the design steps of the workshop, The following aspects are plished, such as the economic accordance of building the workshop, the distribution of output, mill parision and layout chosen, pass system chosen and pass design of classic production, velocity puting and output planned, mechnical calculation and test,auxiliary equipment chosen, metal balance and water and electricity consume,etc. According to the task requirement, an annual output of 650,000 tons of bars factory is designed. Referring to the domestic advanced rolling technology , rolling equipment, pass and auxiliary equipment choosing, specially, this ensure that the technology is reasonable and chosed equipment is advanced and there is space to produce highprofit rod . Bar is sale by sizing. All kinds of rolling mill can produce bar, such as opentrain mill, Bar to length delivery, barstyle, semicontinuous train and the continuous train. The pattern of continuous rolling bar in horizontal and vertical looper has the specility of the fewer accident, highly efficientand high output. In considering of the successfully producing, high lever automation, and stable quality controlling, the no twist continuous rolling is adopted in this classic production is θ26 bar. The workshop layout and pass paper and arrange pass pape
