摘要： A method for controlling a slice flow of a slurry having two or more component slurries through a headbox for a paper making machine includes, inputting a wire speed of the paper making machine; determining a jet velocity setpoint based on the wire speed; determining a header pressure setpoint for two or more headers to generate the jet velocity determined by the jet velocity setpoint, each header providing one of the two or more component slurries to the headbox; and controlling the slice flow by: generating a first speed command to a first slurry pump to generate a header pressure determined by the header pressure setpoint in a first header; and generating a second speed command to a second slurry pump to generate the header pressure determined by the header pressure setpoint in a second header.

摘要： A method for treating cellulosic fibers to improve paper, board and tissue quality; the method involves splitting fibers from feed pulp into an original portion containing original fibers and a refineable portion containing original fibers. The refinable portion is refined to create a refined portion containing refined fibers. Varying amounts of the original unrefined fibers and refined fibers are blended together to form a recombined slurry that is processed by a paper machine into an optimized paper product. A master control system and fiber measurement system are integrated with the overall system to regulate all processing.

摘要： A method has been developed that estimates from the on line measurements of readily available process variables the proportion of the mass of fiber in the refining zone of a chip refiner relative to the mass with a full refining zone. This estimate of the filling factor is used to determine the margin available to load the refiner and the control action needed to avoid abnormal operation.

摘要： A power saving method for rotating pulp and paper machinery includes a fiber quality measurement device, a control system and a variable speed drive. The power savings method is applied to either fiber refiners or pressurized screens. Pulp stock enters a rotating machine, which is driven by an electric motor. The electric motor receives electrical current from the variable speed drive to implement rotation. The variable speed drive changes a frequency of the electrical current according to input received by the control system. The control system includes a control algorithm to optimize the efficiency of the rotating machine. The control system receives inputs of pressures, flows, consistency and position. The control system also receives input from the pulp quality measurement device. The algorithm calculates the process values and input from the pulp quality measurement device to determine the appropriate electrical current frequency to output to the electric motor.
