Countermeasures and countermeasures for blast furnace dry coke quenching to wet coke quenching

Abstract

The invention provides a coping method and a coping system for transforming dry coke quenching into wet coke quenching in a blast furnace. The coping method includes: constructing a case library for coke dry quenching to wet coke quenching; comparing the furnace condition characterization parameters of the wet coke quenching period with the furnace condition characterization parameters of the coke dry quenching period of each case, and determining the response to the case Strategy quality: Determine the furnace condition characterization parameter standards for the optimal timing of coke dry quenching to wet coke quenching, and build a case library for optimal timing, in which the furnace condition characterization parameters during the dry coke quenching period of each case match the furnace condition characterization parameter standards ; When the current furnace condition characterization parameters match the furnace condition characterization parameter standards, a reminder is generated that it is currently suitable for coke dry quenching to wet coke quenching; the current operating parameters, furnace body data, charge data and optimal timing case database have good quality response strategies Each case is compared, referring to the operating parameters of the wet quenching period of the case with a high degree of matching, and the current coping strategy for the conversion from dry coke quenching to wet coke quenching is generated.

Description

technical field [0001] The invention belongs to the technical field of smelting blast furnace control, and relates to a coping method and a coping system for transforming dry coke quenching into wet coke quenching in a blast furnace. Background technique [0002] As we all know, coke is not only the fuel and reducing agent in the blast furnace ironmaking process, but also the skeleton of the blast furnace. The quality of coke is a key factor that affects the smooth running of blast furnaces, especially for large blast furnaces. Compared with wet coke quenching, dry coke quenching has significant advantages in terms of moisture, average particle size, cold strength, hot strength, etc. Therefore, dry coke quenching is often used in large-scale blast furnace production. However, during the annual repair period of the dry coke quenching production system, it is common practice to replace it with a wet coke quenching system and use it in large-scale blast furnace production, whi...
