An extrusion system and a method using temperature control

Title:

An extrusion system and a method using temperature control

Document Type and Number:

Japanese Patent JP6258962

Kind Code:

B2

Abstract:

Extrusion systems and methods with temperature control are disclosed. The ceramic batch material is flowed through a front section wherein the temperature of the batch material is locally adjusted through its perimeter at multiple locations. The temperature-adjusted ceramic batch material is then extruded through the extrusion die to form the extrudate. Temperatures of the extrudate at multiple outer surface locations having different azimuthal positions are measured. The temperature adjustment of the ceramic batch material is then controlled in a first feedback loop to control the shape of the extrudate based on the measured outer surface temperatures. The front section can also be cooled using a second control loop.
