随着科学的发展，轧钢生产行业与传统机械业进一步紧密的结合在一起。
利用轧钢生产技术，提高轧制产品的质量，减少轧制生产的时间，提高成品率，降低生产成本和提高材料的利用率已经成为轧钢机械设计的主要目标。
而矫直技术是提高板带钢产品表面质量和平坦度的重要环节。
在现代化程度较高的连铸生产线中，连铸坯的矫直设备是必不可少的；在型钢、钢板、钢管等轧钢厂的精整车间，矫直机则更是必备的设备之一。
平直度是评价金属板带质量的重要指标之一，随着用户对板带质量要求的不断提高，板带平直度的控制和改善显得日益重要。
板材矫直机是消除板材平直度缺陷，改善板形的关键设备。
本文介绍了板材矫直机的结构特点,原理分析和功能，并对矫直原理做了详细具体的阐述，对其主要零部件做了准确的计算设计和校核，对矫直机的力能参数和结构参数做了计算，同时对矫直机的发展趋势和实际生产中存在的问题做了简单的阐述。

Use the Steel-rolling production technology to enhance the Rolling products` quality , to reduce the time of rolling , to enhance the rate of good-products .to reduce the production cost and enhance the material`s utilization has become the main aim of the steel rolling machine design. However, the straighting techology is the important part of how to enhance the surface quality and flatness. In the modernization of high degree of continuous casting production line，The continuous casting slab of straightening equipment is indispensable。
In the steel, steel plates, steel rolling`s finishing workshop, Straightening machine is one of the necessary equipment. Straightness is one of the important indexes with quality. As the users` demand for the quality requirements enhances unceasingly, the steel`s straightness control and improvement is becoming more and more important. The straightening machine is the key equipment to eliminate straightness` defects.This article introduces the structure`s characteristics of the straightening machine, theory analysis and function, a straightening theory in detail. Accurate calculation design and check of it`s main parts. The Power Parameter of straighter and structure parameters are calculated.At the same time, there is a simple elaboration of the development trend of straighter and the problems of actual production.Keywords: straightening machine，Power Parameter，structure parameters，Balance hydraulic cylinder目录任务书.......................................................................................................................................i中文摘要...............................................................................................................................i i ABSTRACT......................................................................................................................i i i 第1章绪论..
