1、河北聯(lián)合大學(xué)輕工學(xué)院QINGGONGCOLLEGE,HEBEIUNITEDUNIVERSITY畢業(yè)設(shè)計(jì)說明書設(shè)計(jì)題目:年產(chǎn)200萬噸寬厚板軋鋼車間設(shè)計(jì)學(xué)生姓名:學(xué)號:專業(yè)班級:08軋鋼1班學(xué)部:材料化工部指導(dǎo)教師:2012年05月22日摘要摘要根據(jù)設(shè)計(jì)任務(wù)要求,進(jìn)行年產(chǎn)200萬噸寬厚板車間設(shè)計(jì)。設(shè)計(jì)要求設(shè)備較為強(qiáng)大,能生產(chǎn)多品種多用途優(yōu)質(zhì)寬厚板。設(shè)計(jì)內(nèi)容包括建廠經(jīng)濟(jì)依據(jù)、產(chǎn)品大綱分配、原料選擇、總道次選擇、軋機(jī)比較及選擇、壓下規(guī)程計(jì)算、速度計(jì)算、溫降計(jì)算、力能計(jì)算、軋輥校核、凸度計(jì)算、輔助設(shè)備選擇等。
2、高級中厚板具有高強(qiáng)度、高性能,一般力能較小的寬板軋機(jī)不能進(jìn)行生產(chǎn)。為了在新疆建立高檔次寬厚板車間,軋制包括管線鋼在內(nèi)的多種優(yōu)質(zhì)寬板,特別選擇強(qiáng)力變形的中厚板軋機(jī)。設(shè)計(jì)中盡量采用先進(jìn)的厚板生產(chǎn)工藝和帶輥形調(diào)整的軋機(jī),并與許多新技術(shù)系統(tǒng)相結(jié)合來保證生產(chǎn)高精度寬厚板。選用了德國西門子公司提供的CVC軋機(jī)與正負(fù)彎輥系統(tǒng),從而能使設(shè)備與工藝水平各方面都居于領(lǐng)先水平。軋制線采用高水平的控軋控冷工藝,為了減少控軋工藝對產(chǎn)量的影響,采用多塊鋼交叉軋制工藝及中間噴水冷卻,加速冷卻裝置采用噴射冷卻和層流冷卻組合形式,在該
