Typical product Q235 (10mm 1700mm 6000mm, 25mm 1000mm 6000mm, 4010mm 1450mm 4000mm) steelbased, to determine the typical products of the process, to determine the the mill arrangement of workshop equipment selection, and to develop typical products and reasonable reduction procedures to calculate the rolling force parameters, such as: rolling force calculation, the calculation of the deformation resistance and transmission torque calculation. The check rolls intensity and calculate the capacity of the motor to the appropriate choice of rolls and motor. To determine workshop work systems and working hours, calculated the annual production of the mill, according to the typical product of the process and the size of the rolling determine workshop layout, such as device spacing, warehouse area, and draw the workshop floor plan . Analysis of the economic indicators of the workshop. And to take effective environmental protection measures, such as the greening of the workshop, waste gas and waste recycling and so on.Keywords: plate workshop, outline, metal balance sheets, rolling force, deformation resistance, drive torque 第 3 頁(yè)目錄設(shè)計(jì)說(shuō)明……………………………………………………………………………...11 前言………………………………………………...................................................8 我國(guó)中厚板生產(chǎn)技術(shù)現(xiàn)狀 ............................................................................8 中厚板軋鋼生產(chǎn)線的工藝裝備 .........................................................8 中厚板的生產(chǎn)技術(shù)是產(chǎn)品的核心 .....................................................9 中厚板軋機(jī)生產(chǎn)工藝的發(fā)展趨勢(shì) ................................................................9 中厚板軋機(jī)生產(chǎn)工藝方案 .................................................................9 產(chǎn)品質(zhì)量及交貨狀態(tài) .......................................................................10 我國(guó)中厚板軋機(jī)的發(fā)展方向 ......................................................................12 國(guó)內(nèi)中厚板軋機(jī)的改造 ..............................................................................13 圍繞提高軋機(jī)的目能力水平進(jìn)行改造 ...........................................13 圍繞提高裝備水平進(jìn)行改造 ...........................................................14 板坯連鑄比 .......................................................................................15 軋機(jī) ...................................................................................................15 新技術(shù)和新工藝 ...............................................................................152 中厚板產(chǎn)品方案………………………………………………………………….16 編制產(chǎn)品大綱 ..............................................................................................16 編制金屬平衡表 ..........................................................................................16 成材率概念 .......................................................................................16 金屬 平衡分析 ...................................................................................17 第 4 頁(yè) 鋼板的化學(xué)成分 ......................................................................18 鋼板尺寸偏差 ..........................................................................193 中厚板的生產(chǎn)工藝和軋制區(qū)的設(shè)備…………………………………………….21 中厚板生產(chǎn)工藝流程 .................................................................................21 典型產(chǎn)品的工藝流程 .................................................................................21 軋制區(qū)設(shè)備選擇 .........................................................................................25 中厚板軋機(jī)型式 ..............................................................................25 中厚板軋機(jī)的布置 ..........................................................................25 軋機(jī)主機(jī)列 ......................................................................................26 工作機(jī)座的結(jié)構(gòu) ...............................................................................26 換輥裝置 ..........................................................................................29 軋制區(qū)其它設(shè)備 ..............................................................................29 輔助設(shè)備的選擇 .......................................................................................29 加熱爐選擇 ......................................................................................29 剪切機(jī)選擇 ......................................................................................31 熱矯直機(jī)選擇 ................................................................................
