Abstract

The invention relates to a billet temperature calculation method for a heating furnace, and belongs to the technical field of heating furnace optimal control. The method calculates the billet surfaceheat flow through the radiation exchange area, and comprises the following steps: S1, dividing a heating furnace into a plurality of model sections along the furnace length direction; s2, calculatingthe radiation exchange area among the furnace walls, the steel billets and the furnace gas of each section firstly, then calculating the derived radiation coefficient through the radiation exchange area, and then obtaining the steel billet surface heat flow; and S3, calculating the temperature distribution of the section of the billet by adopting a differential method. The surface heat flow of thebillet is calculated by adopting a radiation exchange area method, the influence of a black body material is introduced into radiation heat flow calculation, and the method is more suitable for modelcalculation of a heating furnace with the black body material.

Description

technical field [0001] The invention belongs to the technical field of heating furnace optimization control, and relates to a billet temperature calculation method of a heating furnace. Background technique [0002] Heating furnace is an important equipment in steel rolling production, and the quality of the heated billet directly restricts the quality of finished products; at the same time, heating furnace is also the main energy-consuming equipment in steel rolling production, and its energy consumption accounts for about 70% of the entire steel rolling process. In order to reduce the energy consumption of the heating furnace, many energy-saving materials and energy-saving technologies have been researched and developed. The use of blackbody materials on the heating furnace is an effective and feasible measure to reduce the energy consumption of the heating furnace, and it has been used more and more in recent years. [0003] Installing the black body element on the furna...
