Abstract
As an important part of establishing or reconstruction of a manufacturing enterprise, the workshop design is the key technology to the success of the whole project. Nowadays, the iron and steel enterprises are stepping into a market environment which is both flourishing and full of competition. So only with a high quality of the product cannot bring to the success of the enterprise. In the market environment price plays a more and more important part. Cost control is important. So the systematic thought has been adopted in the process of the rolling procedure design.
In this paper with the diameter of 16mm spring steel 60Si2CrVA steel as representative. Then the design is set out in certain procedures, mainly including the making of product outline, choosing mills, choosing pass system, designing of pass in typical products force and energy parameters calculating and checking, auxiliary equipment, choosing workshop arrangement.
The techno-economy analysis is an important phase in the project of reconstruction design of engineering. In the last part of this paper, the techno-economy analysis and evaluation of this project are presented according to correlated theory and calculated data.
Keywords: workshop design; pass design; bar
