Abstract

The invention discloses an AOD (argon oxygen decarburization) furnace energy consumption optimization method based on an energy carrier, and belongs to the field of data processing. The AOD furnace energy consumption optimization method includes the steps: determining an AOD furnace energy consumption optimization model parameter set according to a production process; building energy balance constraint conditions of the parameter set based on material balance; building an energy consumption optimization model for an AOD furnace energy carrying value according to the energy balance constraint conditions; solving the energy consumption optimization model by an adaptive mutation rate genetic algorithm to obtain the optimized value of an objective function of the AOD furnace energy consumption optimization model; optimizing / adjusting the burdening amount or the burdening proportion of an AOD furnace and adjusting / controlling material consumption of the AOD furnace according to the optimized value of the objective function of the AOD furnace energy consumption optimization model; and greatly reducing the comprehensive average energy consumption of the AOD furnace based on the energy carrier on the premise of ensuring indexes such as various processed and product performances of the AOD furnace to meet requirements by the aid of existing equipment conditions. The AOD furnace energy consumption optimization method can be widely used for the field of comprehensive average energy consumption control for the AOD furnace.

Description

technical field [0001] The invention belongs to the field of data processing, in particular to an energy consumption control method for industrial production devices. Background technique [0002] AOD furnace (Argon Oxygen Decarburization furnace), is the refining equipment of the argon oxygen refining method, named after the abbreviation of the English name of the method. [0003] The shape of the AOD furnace (hereinafter referred to as AOD) is similar to that of a converter. The furnace body is placed on a support ring that can be tilted back and forth, and is fixed by pins. The bottom side of the furnace is equipped with spray guns that blow gas into the molten pool horizontally. The number of spray guns varies according to the tonnage of the furnace, generally 2 to 3. The meeting point of the extension lines of the lance coincides with the vertical axis of the furnace. The spray gun is composed of inner tube (copper) and outer tube (stainless steel). The inner tube is ...
