Embodiment Construction

[0025] In order to better understand the present invention, the invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0026] In order to solve the problems existing in the prior art, the present invention provides a hearth accumulation diagnosis and processing method based on the case library. Specifically, the present invention uses the temperature detection data of the blast furnace, the slag iron test data, the tuyere area working data and Establish a database for slag iron test data and other information, use pattern recognition and nested recognition technology to find out the hearth accumulation mode, and various hearth accumulation modes form the accumulation case library, and set the treatment measures for each accumulation case in the accumulation case library , the treatment measures of each case constitute the processing mode library; then collect the data in the furnace in real time, match the accumulated ...

Abstract

The invention discloses a hearth accumulation diagnosis and treatment method based on a case library. The hearth accumulation diagnosis and treatment method comprises the following steps: (1) collecting temperature detection data, cooling water volume data, cooling water temperature data, tuyere zone work data and iron slag testing data in real time; (2) storing data of step (1) in a database; (3) carrying out mode recognition by utilizing the data in the database, and screening out a slag iron key mode, a furnace temperature key mode and a cooling water temperature difference and thermal load key mode through nested recognition; arranging and combining the three key modes to form an accumulation case library; (4) setting a treatment mode library aiming at the accumulation case library; (5) collecting in-furnace data, automatically matching the collected data with a case in the accumulation case library, calling a corresponding treatment measure from the treatment mode library if matching happens, and sending a signal to a control system. The method disclosed by the invention is capable of comprehensively, timely and accurately diagnosing a hearth accumulation situation and timely treating a hearth accumulation problem aiming at the hearth accumulation situation.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting control, in particular to a hearth accumulation diagnosis and processing method based on a case library. Background technique [0002] With the development of blast furnace ironmaking, the large-scale blast furnace has advanced by leaps and bounds in recent years, and the internal volume of China has exceeded 1000m 3 There are more than 500 large-scale blast furnaces, of which the inner volume exceeds 2000m 3 There are more than 200 blast furnaces in China. The larger the blast furnace, the more difficult it is to manage and maintain the blast furnace. For the blast furnace, the stacking of the hearth is one of the most important factors affecting the working conditions of the blast furnace. The stacking of the hearth is due to the Decreased coke quality, lower furnace temperature, water leakage, etc. will reduce the liquid permeability of hearth coke and affect the discharge of s...
