950可逆式轧机压下系统的设计
摘要
随着世界经济的迅猛发展，市场对钢铁的需求量随着提高，对质量的要求也不断的提高，轧钢生产中，初轧机无可替代，初轧机起着很关键的作用，而在初轧机中，压下系统装置尤为重要，此文中设计的是φ950可逆式轧机的压下系统。在文中大致的介绍初轧机发展的情况以及发展的趋势，了解φ950可逆式轧机的主传动，考虑压下螺丝的阻塞问题,确定了φ950可逆式轧机的压下系统的方案选择，通过φ950钢坯轧制表中断面尺寸和压下量计算轧制力，确定压下系统合适的电机、减速机、联轴器、以及压下系统中重要的零件部分,压下螺丝和压下螺母的尺寸，通过计算对压下螺丝和压下螺母进行校核，除此之外，设计合适尺寸的蜗轮蜗杆，最后说明一下机械设备的润滑、环保、以及经济性分析。

Design of 950 reversible mill system

Abstract
    With the rapid development of the world economy, market demand for iron and steel with the increase, of quality requirements are also constantly improve rolling production, blooming mill is irreplaceable, blooming mill plays a very crucial role, and in blooming mill, the pressure system device is particularly important. In this paper, the design of the is Phi 950 reversing mill pressure system. In this paper we introduce the bloomingmill development situation and development trend, understand the main drive with 950 reversible rolling mill, considering blocking screw, determine the choice of the 950 reversible rolling mill press down system, the section size of phi 950 billet rolling table and calculating rolling force, pressure system determine the appropriate motor, reducer, coupling, and some important parts of the system under pressure, pressure screw and nut size under pressure, through the calculation of the pressure screw and nut pressure check, in addition, the design of suitable worm size, the analysis of mechanical equipment lubrication, environmental protection, and economic.
