System for optimizing optimal furnace temperature set value based on data mining

Abstract

The invention relates to the technical field of optimizing a furnace temperature set value of a walking beam type heating furnace in the combustion process, in particular to a system for optimizing the optimal furnace temperature set value based on data mining. The system comprises a data processing module and a data mining analysis module. A data processing process mainly comprises the following steps: acquiring the real-time data, and acquiring the temperature, flow and related production data of each furnace section in the heating furnace; combining the acquired production data and steel billet rolling data into a data mining analysis sample object, and storing a mining result in a background database according to a certain rule model, thereby forming a rule knowledge base; and finally acquiring the optimal furnace temperature set values of different steel billets in each section of the heating furnace from the knowledge base. The system provided by the invention can be used for optimizing and setting an optimal furnace temperature set value curve of the walking beam type heating furnace. For various steel billets, the optimal control guidance can be supplied to the control system, thereby improving the combustion process of the steel billets in the heating furnace, increasing the heating quality and lowering the energy consumption of the heating furnace.

Description

technical field [0001] The invention relates to the technical field of optimization of the furnace temperature setting value in the combustion process of a walking beam heating furnace, in particular to a data mining-based optimal furnace temperature setting value optimization system. Background technique [0002] For the multi-stage heating continuous heating furnace, in order to meet the requirements of the rolling process and the billet heating system, the temperature difference control of each stage is adopted. Different billet heating systems require corresponding furnace temperature control to meet the billet heating requirements. Often due to the influence of factors such as the furnace structure, combustion method, tapping rhythm, equipment operation status, and operator technical level, the furnace temperature control cannot meet the billet rolling requirements, so insurance methods are often adopted. Within the allowable range, the furnace temperature is used to bu...

Problems solved by technology

Often due to the influence of factors such as the furnace structure, combustion method, tapping rhythm, equipment operation status, and operator technical level, the furnace temperature control cannot meet the billet rolling requirements, so insurance methods are often adopted. Within the allowable range, the furnace temperature shall be burnt according to the upper limit of the temperature regulation, which will not only cause the heating quality of the steel billet to be unguaranteed, but also lead to serious waste of fuel and unnecessary exhaust gas emissions

[0003] Especially for the heating furnace of special steel enterprises, there are many types of billets to be heated, the specifications change frequently, and the holding time for rolling is relatively long

Therefore, the heating system of the special steel heating furnace is relatively complicated
