ANTI BREAK - OUT SYSTEM FOR CONTINOUSES CASTING MACHINE IN INDUSTRY 4.0

Abstract

The changing face of industry is increasingly loading automation. The fourth industrial revolution is a sign for the current trend of modernization and automation of individual workplaces and equipment. As part of the modernization of the continuous casting machine No. 1 (ZPO1) of Třinecké železárny, a. s., (TŽ), the electromechanical oscillating mechanism has been recently replaced by a modern hydraulic oscillating mechanism from Danieli. However, due to the implemented modernization interventions, it was necessary to address other important aspects associated with the control of continuous casting technology, such as the functionality of anti-breakout system (so-called DGS) which was based in 2000 on the analysis of a digital signal from the cardan shaft to change the time shifts of the frequency of the oscillating mechanism. This signal, by switching to the new hydraulic cylinder drive technology, was no longer available for calculation in breakout prediction system, and therefore it was necessary to develop a new way of evaluating the breakout alarm called ABS. At the same time, however, new possibilities have emerged to further develop the continuous casting management process to meet the requirements of the Industry 4.0 concept. The new prediction system is currently based on friction force change in hydraulic cylinder. Friction coefficient is directly calculated, from analogue signals coming from hydraulic oscillation machine. The evaluation criteria are automatically set according to steel grades.
