Mill is rolling ingot and continuous slab lumber production processes. Produced by rolling steel, high productivity, variety, continuity of the production process, easy to realize the advantages of automation. So the mill is widely used, about 90% of the steel is rolled through veteran. The quality of mill equipment has a great impact on the effectiveness of the rolling mill and rolling mill industry occupies an extremely important position in the national economy. These also describes the necessity and importance of this design, and the design itself is also learned to play our role in testing. Design includes selection, rolling force calculation and the main motor capacity transmission scheme selection, checking roll stability, design work roll and backup roll and strength check, roller bearing selection, choose the connection shaft universal calculation, lubrication selection methods, environmental protection and economic analysis. Design The design of the conclusions mill main drive system has better speed performance, wide speed range, fast response, highrolling quality, smooth transmission, good lubrication conditions, low noise, and long life advantages, but also to meet the conditions of the parts, fully meet the design requirements. Keyword:The main drive。 Roughing mill。 Reversible rolling。 Work roll。 Supporting rollers 遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì) 第 III 頁(yè) 目 錄 1 緒論 ....................................................................................................................................... 1 選題背景及目的 .......................................................................................................... 1 軋鋼機(jī)械國(guó)內(nèi)外發(fā)展概況 .......................................................................................... 1 設(shè)計(jì)的主要內(nèi)容和方法 .............................................................................................. 4 2 總體方案設(shè)計(jì) .................................................................................................................... 5 概述 .............................................................................................................................. 5 方案比較 ...................................................................................................................... 5 方案分析 ...................................................................................................................... 6 3 軋輥參數(shù)的確定 ............................................................................................................... 8 設(shè)計(jì)參數(shù) ...................................................................................................................... 8 軋輥基本尺寸 .............................................................................................................. 8 軋輥材料的選擇 ........................................................................................................ 10 4 電機(jī)容量選擇 .................................................................................................................. 11 軋制力計(jì)算 ................................................................................................................ 11 變形阻力 ......................................................................................................... 11 平均單位壓力和軋制力 ................................................................................. 16 軋輥驅(qū)動(dòng)力矩 ................................................................................................. 17 初算電機(jī)功率及靜力矩 ............................................................................................ 21 電動(dòng)機(jī)校核 ................................................................................................................ 24 5 校核軋輥穩(wěn)定性和強(qiáng)度 ............................................................................................... 25 軋輥穩(wěn)定性校核 ........................................................................................................ 25 軋輥的強(qiáng)度校核 ........................................................................................................ 26 彎曲應(yīng)力 ......................................................................................................... 29 接觸應(yīng)力 ......................................................................................................... 30 6 軋輥軸承與萬(wàn)向 連接軸的選擇計(jì)算 ........................................................................ 31 軸承選擇與壽命計(jì)算 ................................................................................................ 31 萬(wàn)向連接軸的選擇 .................................................................................................... 32 十字軸的校核 ............................................................................................................ 32 7 潤(rùn)滑方式 、環(huán)保性及經(jīng)濟(jì)分析 ................................................................................. 34 潤(rùn)滑方式的選擇 ........................................................................................................ 34 環(huán)保性及經(jīng)濟(jì)分析 ....................................................................
