Embodiment Construction

[0062] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0063] ginseng figure 1 As shown, an embodiment of the present invention provides an evaluation method, which can be used to evaluate the status of the blast furnace distribution, to judge whether the status of the blast furnace distribution is normal or abnormal, and then can provide strategies for the rationality and adjustment of the blast furnace distribution system sexual basis. The evaluation method will be introduced below based on a preferred implementation manner. The evaluation method includes the following steps.

[0064] Step: collect the action signal of the distribution device and the ...

Abstract

The present invention provides a method and system for evaluating the state of blast furnace charge distribution. The evaluation method includes: collecting the action signal of the charge distribution device and the current charge information, and determining to enter the stage of charge distribution; collecting the characteristic parameters of the furnace condition in the charge stage to obtain The actual change situation of the furnace condition characterization parameter; according to the Cartesian product of the pre-acquired charge type, furnace condition characterization parameter and theoretical change situation, compare the actual change situation with the theoretical change situation, wherein the The theoretical change situation includes a standard cloth theoretical change situation and at least one abnormal type of abnormal cloth theoretical change situation; according to the comparison result between the actual change situation and the theoretical change situation, the current distribution situation is judged. The invention accurately and effectively correlates the furnace throat temperature, air supply pressure, etc. with the material distribution. Compared with relying on experience to infer the cause from many factors, the reliability of the evaluation result is improved, and the guiding significance for adjusting the blast furnace material distribution system is enhanced.

Description

technical field [0001] The invention belongs to the technical field of smelting blast furnace control, and relates to a blast furnace material distribution status evaluation method and an evaluation system. Background technique [0002] Blast furnace distribution usually refers to the process of distributing coke and ore and other furnace materials from the material tank into the high-temperature and high-pressure furnace body in a certain way. Usually, the blast furnace material distribution is carried out successively at intervals. Specifically, the distribution of coke and ore is taken as an example: first, the ore is poured into the material tank through the feeding device, and the material flow valve at the lower end of the material tank is opened with a preset opening, so that The ore flows out of the material tank and falls on the inclined chute, and then slides down along the chute to the material surface in the furnace to realize the ore distribution; next, the mate...
