基于攀钢梁厂4kgm重轨产品研究设计书深刻.docVIP

本科毕业设计（论文） 基于攀钢轨梁厂43kg/m重轨产品设计 摘 要 钢轨除了要求具有高强度和高耐磨性外，还需要具有良好的表面质量和外形尺精度，而孔型设计是否合理，直接影响钢轨的尺寸精度和质量。为了使钢轨的产量及质量达到较高的水平，在生产中采用合理的孔型系统和设计方法是必要的。 本论文将结合攀钢轨梁厂的实际情况和43kg/m重轨的特点从以下几个方面展开：43kg/m重轨从坯料选择到成品发货的系列工艺设计，并以此为依据对车间进行平面布置。对43kg/m重轨的延伸孔、帽型孔、轨型孔、成品孔的断面孔型设计，在此基础上设计950轧机、800I架轧机，800II架轧机、850轧机相应的配辊图设计和导卫装置。设计43kg/m重轨轧制规程，制定相应的速度制度，计算各道轧制相应的力学参数，并在此基础上对电机能力进行校核，证明轧制规程和孔型断面设计的合理性。 关键词：43kg/m重轨 孔型设计 校核 ABSTRACT In addition to the requirements of rail with a high strength and high wear resistance, but also has a good surface quality and precision of foot shape, and pass design is reasonable, the size of a direct impact on rail precision and quality. In order to make rail output and high quality, reasonable in production and design of the pass system is necessary. This paper will combine the rail beam factory Pangang the actual situation and 43kg / m heavy rail from the characteristics of the study the following aspects: 43kg / m heavy rail options from blank to finished shipping a series of process design and use it as the basis of workshop to optimize the layout. Of 43kg / m heavy rail extension of holes, hole-type cap, track-type holes, finished cross-section of the hole-hole design, the design on the basis of 950 mill frame, 800I mill frame, 800II frame mill, 850 mill roll with the corresponding design and guide and guard. The design of 43kg / m Heavy Rail Rolling order to develop the speed of the corresponding system, the calculation of the Road, the mechanical parameters of rolling, and on this basis to check the electrical capacity to prove a point of order and pass rolling of a reasonable cross-section design sexual.
