1780R2粗轧机压下系统设计
摘要
随着钢铁工业的不断发展，轧机作为作为主要的轧钢设备也在不断的更新和发展。1780热带钢连轧机是现代热带钢连轧机的典型代表。其粗轧机采用电动压下系统。结构简单、维护方便、调整范围大、调整迅速。能满足轧制精度的要求。本文对1780R2粗轧机压下系统进行了系统的设计计算，主要介绍了轧钢技术国内外的发展概况和热带钢连轧机的现状及发展趋势，并且系统的分析比较了各种压下系统的优缺点。最终确定了1780R2粗轧机压下系统的最优设计方案。在此基础上，对压下系统进行了设计计算。主要包括压下电机的容量选择、直线环面蜗杆减速器基本尺寸的设计计算、蜗杆轴的强度校核、压下螺丝和螺母的强度校核及轧机机架的强度校核。本文还简要介绍了润滑方式的选择、安装试车规程以及经济性和环保性的分析等。构成了完整的压下系统设计。

The Design of Pressure System of 1780R2 Rude Rolling Mill
Abstract
With the continuous development of the iron and steel industry, mills as the major rolling equipment are also continuously updating and developing. 1780 hot strip rolling mill is a typical of hot strip rolling mill in modern. Its rude rolling mill use of electric pressure system, it has the simple structure, the easy maintenance, large adjustment range and the rapid adjustment. It can meet the accurate requirement of 1780R2 rude rolling mill in the paper, it mainly introduces the rolling technology developments at home and abroad hot strip rolling mill of the status and the development trend, and systematically analysis the advantages and disadvantages of the pressure system. Eventually determine the options of optimal of design system of 1780R2 rude rolling mill. It carried on designing and calculating to the pressure system in this foundation, it including of the options of pressure motor of capacity, the calculation of linear-toroidal worm of reducer basic size, the strength checking of worm axis, the strength checking of adjusting screw and nut and the strength checking of mill housing . Also gave a brief account of the choice of mode lubrication, test order and the analysis of economic and environmental in the paper, and so on. Constituted an integrity of design of pressure system.
