PP41控制器在连铸电液伺服自振式结晶器控制系统中的应用

针对传统的电动机驱动偏心凸轮式结晶器振动台架所存在的缺点，开发研制了一种新型的基于电液伺服技术的自振式结晶器及其控制系统。贝加莱的PP41是一款集成了高性能PLC与数字量I／O功能的显示单元，本文介绍了以它为核心搭建的连铸电液伺服自振式结晶器控制系统的构成，以及控制程序和监控画面设计。应用实践表明，该工艺显著改善了铸坯质量并大大提高了拉坯速度。

Application of PP41 Controller in the Control System of the Electro-hydraulic Servo VIBROMOLD of Continuous Caster

Aiming at the existing shortcomings of the traditional motor- driving mold oscillation table with the mechanical structure of eceentric cam, the engineers designed and developed a new VIBROMOLD and its control system based on electro-hydraulic servo technology. B ＆ R＇s PP41 display controller is a display unit which integrates the functions of high performance PLC and digital I/0. The paper introduces the constitution and design of the control program and the monitoring graphics of the control system of the continuous caster＇s electro-hydraulic servo VIBROMOLD constructed by using PP41 as the core of the system. The applied practice demonstrates that the billet quality has been improved and the casting speed has been enhanced with the VIBROMOLD technology.
