900td平板玻璃(熔窑工段)工艺本科生毕业设计 关键词:浮法玻璃、熔窑工段、设备选型、工艺计算。 Abstract The design introduced the technical process of 900t/d float glass production line. During the planning, for the raw material, the computation of material has been made; and for the melt section, the melting kiln various spots size, The heat balance and the choose of the equipment have been calculated with reference to the domestic and foreign materials and the experience, the environmental protection importance and environmental protection measure have been analyzed. With reference to factory date, under the technology arrangement correlation knowledge foundation, the factory horizontal plan about the storage, the melting kiln, the tin trough and product storage has been finished. The melting kiln structure has been concretely introduced, the horizontal plan and the sectional drawing of the melting kiln, small mouth composition and card neck structure drawing have been draw up. The entire design consulted the main design mentality of present float glass production; took the domestic and foreign advanced technologies; carried on the entire automated production; reflected at present floats production to compare the high level. keywords: float glass; melting section; choose of the equipment; process calculation. 目录 前言 1 第一章 浮法玻璃工艺方案的选择与论证 3 1.1平板玻璃工艺方案 3 1.1.1有曹垂直引上法 3 1.1.2垂直引上法 3 1.1.3压延玻璃 3 1.1.4 水平拉制法 3 1.2 浮法玻璃工艺及其产品的优点 4 1.3 浮法玻璃生产工艺流成图见图1.1 5 图1.1 5 第二章 设计说明 6 2.1设计依据 6 2.2工厂设计原则 7 第三章 玻璃的化学成分及原料 8 3.1 浮法玻璃化学成分设计的一般原则 8 3.2 配料流程 9 3.3 其它辅助原料 10 第四章 配料计算 12 4.1 于配料计算相关的参数 12 4.2浮法平板玻璃配料计算 12 4.2.1设计依据 12 4.2.2配料的工艺参数; 13 4.2.3计算步骤; 13 4.3平板玻璃形成过程的耗热量的计算 15 第五章 熔窑工段主要设备 20 5.1 浮法玻璃熔窑各部 20 5.2熔窑主要结构见表5.1 21 5.3熔窑主要尺寸 21 5.4熔窑部位的耐火材料的选择 24 5.4.1熔化部材料的选择见表5.3 24 5.4.2卡脖见表5.4 25 5.4.3冷却部表5.5 25 5.4.4蓄热室见表5.6 25 5.4.5小炉见表5.7 26 5.5玻璃熔窑用隔热材料及其效果见表5.8 26 第六章 熔窑的设备选型 28 6.1倾斜式皮带输送机 28 6.2毯式投料机 28 6.3熔窑助燃风机 28 6.4池壁用冷却
