METHOD FOR VISUALIZATION OF COOLING PROCESS OF EXTRUDED MATERIAL

摘要

A method for visualization of cooling process of extruded material, wherein the melt temperature at the outlet of the extruder and speeds of extruded material are measured, the measured signals are converted into digital codes that are transmitted over a communication channel to an operator's console and the measured values are displayed ​​on the operator’s panel. At the same time on the basis of mathematical description of the cooling process of extruded material and measurements in real time the temperature distribution is additionally calculated through the thickness of extruded material and length of cooling area, and corresponding image is synthesized on the operator’s panel.
