봉형상 압연공정의 롤패스 및 롤형상 설계용 대화식 설계보조시스템 개발

Abstract

In this sutdy, a Computer-Aided-Design system for supproting roll pass and profile design in bar rolling, where simple shapes like round and square bars are prouced, is developed in order ot minimize trial and errors in the industry. Interactive design methodology was used in the developed system to provide various design examples from which decision for optimal design can be made. In order to effectively assist the interacitve design process, many relable design data such as material flow, roll force, torque, and power are predicted based on empirical formula. In addition, empirical design rules and designed process database are proveded in table forms and in user-friendly representstions. Roll velocity calculations considering the forward slip and temperature variations based on an approximate heat transfer model were considered in the present system. According to applications of the system for several cases, the developed system is beneficial in implementing various design parameters for roll pass and roll profile designs in bar rolling for a given product geometry in a short period of time.
