Abstract: A method and device for blast furnace state monitoring based on multi-modes fusion. In the process of blast furnace state monitoring, the concept of sub-mode is introduced, and the method for pre-acquisition and multi-modes weighted fusion by sub-mode is proposed to monitor blast furnace state. After preprocessing the main parameter data of the blast furnace, several sub-modes of the blast furnace and their corresponding blast furnace state indication variable data are obtained by means of a mean shift clustering algorithm. Taking the real-time parameter data of the blast furnace as inputs, the Euclidean distance between the real-time parameter data of the blast furnace and each sub-mode is calculated, and the sub-modes are weighted and fused according to the distance, and the fusion result is the real-time blast furnace state, so as to realize the real-time state monitoring of the blast furnace in a smooth operation.

Abstract: A system and method are provided for determining the trajectory or falling curves of charge material, particularly charge material distributed in a blast furnace. A video is acquired of the charge as it leaves the chute of the charging equipment at various ring positions. The video is converted to still images that are analyzed to obtain calibration and correction factors. These factors can then be used to extract and calibrate a model for the charging program to vary and control the distribution of charge in a vessel.

Abstract: A method for melting steel in an electric arc furnace (EAF). A hot heel is provided in the EAF. Metal scrap is loaded into the EAF. The metal scrap is melted in the EAF. The mass of the hot heel in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0.75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel and the heat that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula.

Abstract: 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.
