1、內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書(shū)摘要本設(shè)計(jì)是年產(chǎn)量為230萬(wàn)噸的中厚板生產(chǎn)車間,其典型產(chǎn)品為16Mn,42×4600mm。在整個(gè)設(shè)計(jì)過(guò)程中,簡(jiǎn)單介紹了中厚板生產(chǎn)技術(shù)的發(fā)展,國(guó)內(nèi)外的差距以及采用的新技術(shù);該車間的主要設(shè)備包括:兩座步進(jìn)梁式加熱爐、翻轉(zhuǎn)機(jī)裝置、高壓水除磷裝置、一臺(tái)四輥可逆式軋機(jī),還有各種附屬設(shè)備。在設(shè)計(jì)時(shí),以設(shè)定的年產(chǎn)量為基礎(chǔ),結(jié)合各產(chǎn)品的市場(chǎng)前景,按規(guī)格合理的設(shè)計(jì)了產(chǎn)品方案,制定了金屬平衡表;并以典型產(chǎn)品為例,制定工藝流程和軋制制度,其中軋制制度包括:壓下制度、速度制度和溫度制度;并進(jìn)行了軋制力計(jì)算、電動(dòng)機(jī)載荷和軋輥強(qiáng)度的校核。設(shè)
2、計(jì)中對(duì)年產(chǎn)量進(jìn)行了計(jì)算,提出各項(xiàng)經(jīng)濟(jì)技術(shù)指標(biāo)以及對(duì)環(huán)境保護(hù)的措施。得出了科學(xué)合理的中厚板車間設(shè)計(jì)方案。最后繪制了一張車間平面圖,最后附有一篇外文資料及譯文。本車間的設(shè)計(jì)特點(diǎn)包括:產(chǎn)品高強(qiáng)度,機(jī)械性能好,采用了先進(jìn)的生產(chǎn)技術(shù),考慮了環(huán)保的要求。從總體上說(shuō),達(dá)到了高產(chǎn)低耗。關(guān)鍵詞:中厚板;軋制制度;船板VI內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書(shū)AbstractInthispaper,aheavyplateplantwhichproduces230ten-thousandtonsperyearwasdesignedinthisthesis.Thetypic
