摘要


采用連續(xù)鑄造方法，可以使全連續(xù)和自動(dòng)化操作成為可能，提高了鑄坯質(zhì)量，減少了生產(chǎn)工序，降低生產(chǎn)成本，故在大型的鋼鐵企業(yè)中得到廣泛地推廣應(yīng)用。本文介紹了最新連鑄技術(shù)的發(fā)展趨勢(shì)以及我國小方坯連鑄生產(chǎn)技術(shù)的現(xiàn)狀和發(fā)展情況。本文所研究的對(duì)象為小方坯連鑄機(jī)拉矯機(jī)，采用漸進(jìn)式五輥拉矯機(jī)。根據(jù)其工作環(huán)境和拉矯設(shè)備的力能參數(shù)，對(duì)R6000小方坯連鑄拉矯機(jī)進(jìn)行結(jié)構(gòu)設(shè)計(jì)，并對(duì)減速機(jī)構(gòu)加以設(shè)計(jì)研究，對(duì)主要零部件進(jìn)行受力分析與強(qiáng)度計(jì)算，針對(duì)原設(shè)備制造、維護(hù)方面的薄弱環(huán)節(jié)加以改進(jìn)。然后用Solidworks對(duì)機(jī)架進(jìn)行三維造型，利用CosmosWorks進(jìn)行有限元分析，較為直觀的觀察到其各處受應(yīng)力，產(chǎn)生應(yīng)變、位移等情況。

ABSTRACT

 

Using the continuous casting method, may cause continuous operation and the automation possibly, raising the slab quality, reducing production processes, reducing production costs .So the large-scale iron and steel enterprises widely pushed up the broad application. This article describes the latest continuous casting technology and the development trend, the status and development of China's small billet continuous casting production technology . In this article , the object of study is straightener for Small Billet Caster ,a gradual straightener with 5 rollers . According to their working environment and the equipment's strength parameters, carry on holistic structure design for R6000 Small Billet Caster straightener and design for reducer, also carry on the stress analysis and the strength calculation to the main spare part, improve something for the weak links of manufacturer and maintenance for the original equipment. Then we carry on the three dimensional modeling to the rack with Solidworks, doing the finite element analysis with CosmosWorks .Then we can more direct-viewing observe its situation of each place subject to stress, strain, displacement and so on.


Keywords :  straightener     structural design     strength calculation
