摘要： In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. Pre-determined valve characteristics for certain types of material are provided, each indicating the relation between flow rate and valve setting for one type of material. According to the invention, a specific valve characteristic is stored for each batch of charge material, each specific valve characteristic being bijectively associated to one batch and indicating the relation between flow rate and valve setting of the flow control valve specifically for the associated batch. In relation to discharging a given batch of the sequence the invention proposes: using the stored specific valve characteristic associated to the given batch for determining a requested valve setting corresponding to a flow rate setpoint and using the requested valve setting to operate the flow control valve; determining an actual average flow rate for the discharge of the given batch; correcting the stored specific valve characteristic associated to the given batch in case of a stipulated deviation between the flow rate setpoint and the actual average flow rate.

摘要： Apparatus and method for obtaining accurate sonic input data from a metallurgical furnace, for accomplishing accurate control of a lance injecting oxygen and/or other substances into the melt. A remotely located hydrophone is placed in sonic communication with a liquid circuit cooling the lance. Sound levels and frequencies are picked up through the liquid, and transmitted to a programmable logic controller which generates control signals operating the lance. An associated real time analyzer compares the sonic signature of the input data to predetermined sonic signature data retained in memory, and adjusts lance operation through the programmable logic controller accordingly in order to operate the furnace optimally. Sonic transmission is more accurate, and the hydrophone is more protected from the harsh furnace environment due to its remote location and employment of liquid sound transmission, when compared to other microphone arrangements.

摘要： The invention relates to the cooling of hot, layered, granular material supported on an air permeable grate through which cooling air passes constantly. Some zones of the material layer have a higher temperature than other zones. Pulses of additional cooling air are passed through the higher temperature zones at such velocity as to enhance cooling and to relayer the material at such zones. In this way the degree of recuperation of the grate cooler can be substantially improved.

摘要： 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.
