  • INLINE EXTRUDATE BOW MEASUREMENT AND CONTROL
    Publication number: 20220324136
    Abstract: Extrusion techniques for reducing bow of an extrudate formed from a ceramic forming mixture. Velocities of an outer surface of the extrudate are measured at a plurality of peripherally spaced measurement locations. The velocities are compared to determine whether there is a velocity bias, and the comparison is used to selectively alter the flow of the ceramic forming mixture.

  • Method for firing ceramic honeycomb bodies in a kiln
    Patent number: 8192680
    Abstract: A method for fabricating ceramic honeycomb structural bodies that includes conveying at least one green honeycomb structural body of a first type and at least one green honeycomb structural body of a second type through a kiln in a manner which reduces cracking or fissures in the fired objects.

  • REAL-TIME, CLOSED-LOOP SHAPE CONTROL OF EXTRUDED CERAMIC HONEYCOMB STRUCTURES
    Publication number: 20120133065
    Abstract: Systems and methods for real-time, closed-loop shape control of extruded ceramic honeycomb structures are disclosed. Methods include extruding batch material through an extruder barrel and through an extruder die using at least one extrusion screw to form the extrudate, and measuring a shape of the extrudate immediately adjacent the die. The batch material water content is determined or measured, at least one of the extruder barrel and screw temperature are measured, and the extrusion screw rotation rate are measured. At least one of the batch material water content, barrel temperature, screw temperature and rotation rate is adjusted to maintain the extrudate shape to within a select tolerance.
