【正文】 第 1 頁設計說明本設計為年產量 180 萬噸的中厚板車間，通過對中厚板市場的調研，介紹了中厚板的發(fā)展狀況，分析了中厚板的市場需求，并針對目前的技術狀況，制定出了合理的產品大綱和金屬平衡表。以典型產品Q235（10mm1700mm6000mm、25mm1000mm6000mm、4010mm1450mm4000mm）鋼板為基礎，通過確定典型產品的工藝流程，確定了軋機的布置形式和車間各設備的選用，并制定出典型產品合理的壓下規(guī)程，計算出軋制力能參數(shù)，如：軋制力的計算、變形抗力的計算和傳動力矩的計算等。校核軋輥強度并計算電機的容量，以選用合適的軋輥和電機。確定車間工作制度和年工作時間，計算了軋機的年產量，根據(jù)典型產品的工藝和軋件的尺寸等，確定車間平面布置，如合理的設備間距、倉庫面積等，并畫出車間平面布置圖。分析車間的綜合經濟指標。并采取有效的環(huán)境保護措施，如車間的綠化、廢氣和廢渣的再回收等。關鍵詞：中厚板車間，產品大綱、金屬平衡表、軋制力、傳動力矩 第 2 頁Design NotesThe design for the annual production of 180 million tons of plate plant, plate market research, the development of the plate, the plate market demand, and the current state of technology, to develop aa reasonable outline of the products and metal balance sheet. 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 頁目錄設計說明……………………………………………………………………………...11 前言………………………………………………...................................................8 我國中厚板生產技術現(xiàn)狀 ............................................................................8 中厚板軋鋼生產線的工藝裝備 .........................................................8 中厚板的生產技術是產品的核心 .....................................................9 中厚板軋機生產工藝的發(fā)展趨勢 ................................................................9 中厚板軋機生產工藝方案 .................................................................9 產品質量及交貨狀態(tài) .......................................................................10 我國中厚板軋機的發(fā)展方向 ......................................................................12 國內中厚板軋機的改造 ..............................................................................13 圍繞提高軋機的目能力水平進行改造 ...........................................13 圍繞提高裝備水平進行改造 ...........................................................14 板坯連鑄比 .......................................................................................15 軋機 ...................................................................................................15 新技術和新工藝 ...............................................................................152 中厚板產品方案………………………………………………………………….16 編制產品大綱 ..............................................................................................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 鋼板的化學成分 ......................................................................18 鋼板尺寸偏差 ..........................................................................193 中厚板的生產工藝和軋制區(qū)的設備…………………………………………….21 中厚板生產工藝流程 .................................................................................21 典型產品的工藝流程 .................................................................................21 軋制區(qū)設備選擇 .........................................................................................25 中厚板軋機型式 ..............................................................................25 中厚板軋機的布置 ..........................................................................25 軋機主機列 ......................................................................................26 工作機座的結構 ...............................................................................26 換輥裝置 ..........................................................................................29 軋制區(qū)其它設備 ..............................................................................29 輔助設備的選擇 .......................................................................................29 加熱爐選擇 ......................................................................................29 剪切機選擇 ......................................................................................31 熱矯直機選擇 ................................................................................
