摘 要

軋鋼就是把經(jīng)過加熱(或冷軋)的坯料通過軋鋼機(jī)軋制變成所需要的成品鋼材。通過軋制，不僅可以成型，而且最重要的是可以增加鋼鐵的力學(xué)性能，配合熱處理和形變強(qiáng)化，使其稱為提高鋼鐵性能的主要途徑。
本文簡(jiǎn)單介紹了軋鋼生產(chǎn)、軋鋼機(jī)械、冷熱軋帶鋼和國(guó)內(nèi)外冷軋機(jī)的發(fā)展概況以及六輥軋機(jī)的種類和各自特點(diǎn)，并對(duì)軋輥方面的理論現(xiàn)狀進(jìn)行了說(shuō)明。然后通過對(duì)六輥軋機(jī)結(jié)構(gòu)的介紹，闡述了工作輥、中間輥、支承輥的工作原理。重點(diǎn)是根據(jù)在給定條件下選擇軋輥材料和對(duì)六輥軋機(jī)軋輥的結(jié)構(gòu)尺寸進(jìn)行設(shè)計(jì)，并對(duì)其進(jìn)行強(qiáng)度、接觸應(yīng)力、撓度方面的校核，以驗(yàn)證其正確性。在數(shù)據(jù)基礎(chǔ)上，通過運(yùn)用AUTOCAD對(duì)冷軋機(jī)彎輥系統(tǒng)輥系裝配圖和各軋輥零件圖的繪制。在完成結(jié)構(gòu)設(shè)計(jì)的同時(shí)對(duì)六輥軋機(jī)軋輥以及工作輥的結(jié)構(gòu)在SolidWorks平臺(tái)上建立三維模型，并對(duì)軟件本身特點(diǎn)和及其應(yīng)用現(xiàn)狀進(jìn)行介紹，從而完成工作輥的三維裝配模型。

ABSTRACT

Rolling mill is turning the materials that heated (or cold rolling) to steel products which are useful through the mill rolling. It is more important to increase the mechanics performance of the steels than to shape it. With the help of the coordinate heat treatment and the deformation strengthens, rolling-mill becomes an important path to enhances the steel and iron performance.
This article introduced the produce of rolling steels, rolling steel machinery, cold and hot rolling strip steels, the type and respective characteristic of the six-roller rolling-mill and the development of cold rolling-mill, and the theory of roller has carried on showing. By introducing the structure of six-roller mill, elaborated the principle of the working roll, the middle roller and the support roll. The point is according to the condition to choose the material of roller and to design its configuration and size, and check of the intensity, the contact stress, the amount of deflection to prove the correctness of the design. The assembly diagram of roller system and detail drawing of every roller are designed by using AUTOCAD. Introducing the characteristic and application of SolidWorks, the three-dimensional model of the six-roller mill roller and the working roll structure has established in the SolidWorks platform, thus completed the three dimensional assembly model of the working roll.


Key words: rolling-mill, rolling, roller, cold rolling
