    摘要: 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.

    摘要: A control strategy for producing high quality extrudates, including the steps of monitoring the temperature of a ceramic precursor batch by measuring the temperature of the batch material either directly or indirectly by measuring the temperature of a component of the extruder proximate to the die and transmitting the temperature data to an extrusion control system which comprises a master controller (106), at least one slave controller (110) and an optional supervisory controller. The supervisory controller determines batch temperature setpoint (102) in order to achieve the desired temperatures for extruding a certain type of batch material based on real time temperature inputs and stored parameters such as batch composition, process throughput, extruder cooling capacity, and the like. The master controller (106) receives batch temperature setpoint from the supervisory controller, and monitors batch temperature and in turn regulates at least one slave controller (110) which controls the flow of coolant (112) to portions of an extruder (114) in contact with the batch material.

    摘要: A honeycomb extrusion apparatus comprises a die body and a flow control device. The die body comprises an inlet end, an outlet end, a central axis, a first set of feedholes, a second set of feedholes, a set of central slots, and a set of outermost peripheral slots. The first set of feedholes extends from the inlet end to an interior interface portion of the die body. The second set of feedholes extends through the die body from the inlet end to the outlet end. The set of central slots extends from the outlet end to the interior interface portion of the die body. The set of outermost peripheral slots is disposed radially outwardly of the central slots. The interior interface portion of the die body is configured to allow flow of the batch material from the first set of feedholes to the central slots and to the outermost peripheral slots.
