机械450热带钢轧机设计【全套图纸】.doc

摘要 带钢主要用于建筑行业，交通运输行业，机械与电器制造业，轻工业及食品工业等部门。也为近代各种口径焊接钢管的原料。是一种用途较为广泛的通用钢材。本课题的研究宗旨在改进旧式带钢轧机的不足，提高生产率、降低工人劳动强度，满足厂方对带材加工的生产需求。 本文主要研究内容：分析了带钢轧机的的受力状况。在对轧制过程力能参数分析的基础上, 将其受力与设备的驱动功率直接建立联系, 通过功能转换计算, 得出了轧机驱动系统的驱动功率的一种计算方法。经算例分析证明: 该方法简化了机选择设备动力的功率计算, 计算结果更为符合实际。 关键词:带钢轧机，受力分析，驱动功率 STRACT hoop mainly uses in constructing the profession, the transportation profession, the machinery and the electric appliance manufacturing industry, departments and so on light industry and food industry.Also for modern each kind of caliber welded steel pipe raw material.Is one use more widespread general steel products.This topic research objective in the improvement old-style strip mill insufficiency, enhances the productivity, reduces the worker labor intensity, satisfies the factory to the strip processing production demand. This article main research content: Has analyzed the strip mill stress condition.In to the rolling process strength could in the parameter analysis foundation, its stress and the equipment actuation power direct establishment relation, through the function transformation computation, obtains the rolling mill to actuate the system the actuation power one computational method.Proved after the example analysis that, This method simplified machine the choice equipment power power computation, the computed result has conformed to the reality. Key word: Strip mill, stress analysis, actuation power 目录 摘要……………………………………………………………………….Ⅰ Abstract………………………………….……………………………….
