The Study Of Roolling Special Channel Steel

Channel section steel is a kind of economic cross section steel which is widely used in many fields such as automobile, aviation, light industry, machinery manufacture and construction. The market needs high quality products with accurate dimension and form. The developed industrial countries are using universal method to produce channel steel and it can produce kinds of high-class products with dimensions. But our country still are using the method of designing pass on rolls of which disadvantages lead to limitations on the dimensions and form accuracy. Vast scale special channel steels are depending on import. By improving the production method and updating the product quality only, the section industry would progress in our country.This article systematically introduced the condition of section producing and the development of analogue simulation technology in our country, installed edge conditions for the simulation of channel steel milling based on rigid-plastic FEM system, developed new functions coded in Visual C++, based on the former simulation system of shape medals rolling. The process of rolling special channel steel is simulated in use of the FEM software. Then, to validate the computational values, rolling experiments were carried out by using lead. Designing a new rolling machine for the experiments is done before. Compared with the computational results, the experiments results meet them well.
