Integrated Extruder Plant Automation with Learning Control

摘要

Integrated automation in a manufacturing plant demands control of manufacturing and material and product flow processes. Efficient data archiving and retrieval, quality control and process automation facilities are essential components which should be deployed to form one coherent system. As managers of extruder plants running look for ways and means for meeting market requirements, the demand for such integrated automation systems is rising. Integrated Process automation involves: - Overall production and process control - Data acquisition, archiving evaluation with feed-back to production planning and process control - Decentral control in local control loops for achieving isothermal extrusion - On-line visualisation of process variables for tighter man-machine interactionProviding the facility for prescribing the ranges of relevant process variables viz. billet temperature, die temperature, profile temperature at die exit, rate of cooling of the profile and extrusion speed is part of the integrated automation system.
