Investigation and Prognosis of Waste Heat Occurrence during the Extrusion Process of Tubular Profiles

摘要: Extrusion is a fundamental procedure of polymer processing and used to produce tubular profiles, foils, cable coatings, etc. Rising energy prices increase the pressure for extruder manufacturers operators cut costs. Nowadays, are forced develop more energy-efficient extruders. One possibility reach that goal reuse occurring waste heat during extrusion process. Operators could use within their own company reduce primary The prediction consumption usage new lines as well existing with products planning stage very important. Additionally recovery has be projected stage. research approach enable construction future production based on theoretical view monitoring real lines. Therefor program was developed forecast amount heat. included main consumers cooling chambers barrel three different single grooved results show some temperature qualifies reutilization. can fully reused. calculates profile finite element difference wherein transfer calculated in radial direction. thermal state simulated at every position line. Furthermore output into coolant calculated. collected data satisfactory often than not. Based concepts were elaborated. Thereupon measures implemented validated.
