【正文】 I 摘 要 本設(shè)計主要闡述了年產(chǎn) 萬噸鎂質(zhì)耐火材料廠在設(shè)計中的重大問題以及方案的選擇。 首先，根據(jù)設(shè)計要求 ， 設(shè)計原則，產(chǎn)品的種類（鎂磚，鎂鋁磚，鎂鉻磚）及 工廠的規(guī)模和生產(chǎn)方法，確定出生產(chǎn)的工藝過程 ， 原料配比和顆粒的組成，各個車間的工作制度等 。 其次， 進行 物料平衡計算， 主機平衡計算，根據(jù)計算結(jié)果進行設(shè)備選型。再根據(jù)設(shè)備在工廠中的安裝要求及檢修要求進行車間房布置。 再次根據(jù)主機設(shè)備的需要對輔助設(shè)備進行選擇。選擇出合理的輔助設(shè)備并且確保主機設(shè)備正常高效運行。 接著 ，對初步設(shè)計完成后的每個車間視其自身的特點進行合理的技術(shù)經(jīng)濟編制。 最后，對設(shè)計中遺留的的問題進行了討論。另外本設(shè)計中穿插有設(shè)備的外形尺寸圖和工藝布置圖，便于閱讀和理解。 關(guān)鍵詞 ：工藝設(shè)計 ,鎂磚 ,鎂鋁磚 ,鎂鉻磚 II Abstract This design describes the major issues of an annual 35,000 tons output of magnesia refractories plant in the design mainly and explained choices of the program. First, according to design requirements, design principles, product type (brick, magnesia brick, magnesiachrome brick), the plant size and production methods,it is to determine the production process, the proportion and position of particles, each workshop work system and so on. Second, it is to work out the material balance, and the host balance. And then, according to the result, it is matching the equipment type and it is arranging the factory according to installation of requirement and examination in the factories. After that, it is to draw up the reasonable technology and economy due to the each workshop39。s self character after finishing the first design. Finally, it is to discuss the missing issues of design. Moreover, there are papers of equipment39。s appearance and arrangement in the design. It is convenient to read and understand. Key words: process design, Magnesia brick,Magnesium aluminum brick,Magnesia chrome brick III 目 錄 1. 文獻綜述 ........................................................ 1 原料 ......................................................... 1 鎂石 ..................................................... 1 2. 結(jié)構(gòu)與形態(tài) .................................................... 2 鎂砂 ..................................................... 3 各種磚的介紹 ................................................. 3 鎂磚 ...................................................... 3 鎂鋁磚 .................................................... 4 鎂鉻磚 .................................................... 5 結(jié)合相 ....................................................... 6 硅酸鹽 .................................................... 6 鎂的氧化物和鐵酸鹽 ........................................ 6 尖晶石結(jié)合物 .............................................. 6 發(fā)展前景 ..................................................... 7 2 設(shè)計原始數(shù)據(jù)及資料參數(shù) .......................................... 8 設(shè)計題目 ..................................................... 8 規(guī)模及產(chǎn)品方案 ............................................... 8 設(shè)計參數(shù) ..................................................... 8 主要材料及動力來源 .......................................... 10 設(shè)計的原則和要求 ............................................ 10 3 生產(chǎn)方法和工藝流程 .............................................. 11 概述 ........................................................ 11 鎂質(zhì)耐火材料的原料 .......................................... 11 制品的使用質(zhì)量要求及標(biāo)準(zhǔn) .................................... 13 提高產(chǎn)品質(zhì)量的途徑 .......................................... 15 直接結(jié)合 .................................................... 16 生產(chǎn)方法的選擇 .............................................. 17 4 工藝計算 ........................................................ 22 物料平衡計算的目的 .......................................... 22 IV 物料平衡計算 ................................................ 22 計算過程說明 ............................................ 22 各種磚型物料平衡計算 .................................... 22 主機設(shè)備選型 ............................................... 34 主機平衡計算 ............................................ 34 原料倉庫、料倉的計算 ........................................ 42 原料倉庫 ................................................. 42 橋式抓斗起重機搬運能力及計算 ............................. 43 成品倉庫的面積確定 ....................................... 45 供料倉計算 ............................................... 45 5 熱工計算 ........................................................ 50 隧道干燥器的選型計算 ........................................ 50 隧道干燥器數(shù)量的計算 ..................................... 50 干燥車數(shù)量的計算 ......................................... 50 隧道窯選型計算 .............................................. 51 窯的規(guī)格和臺數(shù)的確定 ..................................... 52 窯車數(shù)量的確定 ........................................... 53 6 輔助設(shè)備選型 .................................................... 54 給料、計量設(shè)備 .............................................. 54 輸送設(shè)備 .................................................... 54 除鐵設(shè)備 .................................................... 55 7 車間工藝布置 .................................................... 56 工藝布置一般要求 ............................................ 56 破粉碎車間的布置 ............................................ 57 粉碎、磨碎混合工段 .......................................... 57 工段的布置 ............................................... 57 圓錐破碎機的布置 ........................................ 57 管磨機的布置 ............................................ 57 斗式提升機與篩分設(shè)備的布置 .............................. 58 混合設(shè)備的布置 .......................................... 58 成型車間的布置 .............................................. 58 干燥、燒成車間布置 .......................................... 58 V 成品庫布置 .................................................. 59 8 技術(shù)經(jīng)濟指標(biāo) .................................................... 61 總結(jié) .............................................................. 64 參考文獻 .......................................................... 65 致謝 ..................
