摘要： A blast furnace control system may include a hardware processor that generates a deep learning based predictive model for forecasting hot metal temperature, where the actual measured HMT data is only available sparsely, and for example, measured at irregular interval of time. HMT data points may be imputed by interpolating the HMT measurement data. HMT gradients are computed and a model is generated to learn a relationship between state variables and the HTM gradients. HMT may be forecasted for a time point, in which no measured HMT data is available. The forecasted HMT may be transmitted to a controller coupled to a blast furnace, to trigger a control action to control a manufacturing process occurring in the blast furnace.

摘要： A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations. The measurement system is small in dimension, and capable of scanning the charge level in an environment with high temperature, high concentration of dust, and high corrosion in the blast furnace, establishing charge level information into a two-dimensional charge level mode, and obtaining a charge level profile distribution situation in real time, thereby promptly modifying a burden distribution mode.

摘要： Inference is carried out through intermediate hypotheses representing physical states of a blast furnace using HG (Heuristic Grade) in order to comprehensively diagnose the state of the furnace to ascertain optimum actions. Specific parameters are monitored to immediately recognize a transition of conditions inside the furnace to additionally execute the inference. Various types of actions such as defensive actions and offensive actions are covered in this inference. A burden distribution estimation model considering collapse of a coke bed is used for calculating distribution inside the furnace to aid in deciding on an optimum action when an action to alter distribution in the furnace is required as the result of the inference. Creation and alteration of a knowledge base for the inference are carried out without interrupting the inference.

摘要： The present invention discloses a blast-furnace operation method which comprises selecting three factors, i.e. the oxygen volume in blast, the ore/coke and the reducibility of the burden materials as control factors from among these which participate in the variation of heat input and heat output of blast furnace, plotting values of these three factors obtained from the practical operation of efficient blast furnaces on a graph consisting of three parallel axes indicating the three factors, evaluating the conditions of furnace heat with reference to a balanced state of the three plotted factors and adjusting one or more of the three factors in the furnace so all will lie within a suitable range thereby balancing the furnace heat.
