Abstract

The invention belongs to the technical field of plastic processing, and provides an extrusion process material flower inhibition optimization method based on steam flow field simulation, which comprises the following steps: determining optimization operation parameters of steam injection based on flow field simulation; establishing a dynamic correlation model between the optimized operation parameters and process state parameters of the extrusion process; on the basis of the dynamic correlation model and the process state parameters obtained in real time, generating a steam injection control instruction; executing a steam injection action according to the control instruction, and monitoring a material flower inhibition effect generated by the steam injection action at the same time; and comparing the monitored material flower inhibition effect with a preset target effect value, and performing feedback regulation on the generated control instruction based on a comparison result. Through collaborative innovation of flow field simulation optimization, dynamic correlation modeling and real-time feedback regulation, precise control of material flower inhibition is realized, and the control precision is improved. And the production quality and the yield of the plastic particles are obviously improved.
