    Abstract: A system and method of controlling a metal melting process in a melting furnace, including determining at least one furnace parameter characterizing a melting furnace, adding a charge containing solid metal into the melting furnace, detecting at least one charge parameter characterizing the charge, firing a burner into the melting furnace to provide heat to melt the charge, and exhausting burner combustion products from the furnace, detecting at least one process parameter characterizing progress of melting the charge, calculating a furnace efficiency based on the at least one furnace parameter, calculating a predicted process pour readiness time based on the at least one charge parameter, the at least one process parameter, and the furnace efficiency, and controlling the metal melting process based on the predicted process pour readiness time.

    Abstract: A control scheme for a furnace can use real-time and historical data to model performance and determine relationships between different data and performance parameters for use in correcting suboptimal performance of the furnace in real-time. Operational parameters can be logged throughout the cycle for all cycles for a period of time in order to establish a baseline. This data can then be used to calculate the performance of the process. A regression analysis can be carried out in order to determine which parameters affect different aspects of performance. These relationships can then be used to predict performance during a single cycle in real-time and provide closed or open loop feedback to control furnace operation to result in enhanced performance.

    Abstract: An apparatus for controlling blending of a gas mixture containing known components, including first, second, and third control valves for controlling the flow of first, second, and third components, respectively, a first gas density sensor to measure the density of a first mixture of the first and second components, a second gas density sensor to measure the density of a second mixture of the first mixture and the third component, and a controller to determine based on data from the first and second gas density sensors the relative compositions of the first, second, and third components in the second mixture, and to control the first, second, and third control valves to obtain a desired relative composition of the first, second, and third components in the second mixture.
