Abstract

The invention discloses an optimization method for a billet heating model, which comprises the following steps: carrying out combustion calculation, and determining the combustion load, flue gas temperature and flue gas flow of a heating furnace; determining the segmented furnace temperature of the heating furnace according to the combustion load, the flue gas temperature and the flue gas flow; conducting heat transfer calculation according to the segmented furnace temperature, and determining the billet final temperature Tz, the billet segmented specific heat Cpj, the billet segmented heat conduction coefficient lambda j and the billet heating time t; performing billet heating temperature field simulation by adopting a finite difference iteration method to obtain a billet heating calculation model; heating the steel billet according to the steel billet heating calculation model to obtain actual temperature rise data of the steel billet; correcting the billet heating calculation modelaccording to the billet heating calculation model and the actual temperature rise data; according to the optimization method, combustion, heat transfer, billet temperature field simulation and a heating model correction process are integrated, and effective control over billet heating temperature and quality is achieved.

Description

technical field [0001] The present application relates to the technical field of hot rolling of iron and steel, in particular to an optimization method, optimization device and electronic equipment of a billet heating model. Background technique [0002] With the improvement of the quality requirements of steel products, the surface quality requirements of steel products are getting higher and higher, and the requirements for steel rolling are becoming more and more stringent, so billet heating is becoming more and more important. Although the continuous casting and rolling technology has achieved rapid development, the temperature drop and heat loss in the continuous casting process are inevitable. Therefore, heating the slab is an important link in the hot rolling production process of adding steel. Billet heating is a complex physical and chemical process, and mastering the heating rules can realize low-cost and high-efficiency steel rolling. [0003] The heating of the ...
