A method for setting the temperature of heating furnace under variable production rhythm

Abstract

The invention discloses a heating furnace temperature setting method in variable production rhythms. The heating furnace temperature setting method adopts a set of standard heating schedule database, a set of production rhythm collector module and a set of steel billet temperature tracker module, wherein data such as standard time in furnace (Time0) of steel billets with different thicknesses and of different steel types, furnace temperature set values (Tf0(i)) in various heating zones in the furnace and average steel temperature (Ts0(i)) in the various heating zones in the furnace; and the production rhythm collector module is used for acquiring the current tapping time interval of the heating furnace and adopts three working modes, namely the manual setting mode, the rolling line remote transmission mode and the history tracking mode. The heating furnace temperature setting method in variable production rhythms has the benefits as follows: the furnace temperature in different rhythms can be calculated automatically according to the furnace temperature schedule in the standard rhythm, the routine calculation amount is greatly reduced, the on-line calculation speed is improved, and the maintenance workload of process engineers is reduced.

Description

technical field [0001] The invention is used in the technical field of furnace temperature control of a hot rolling heating furnace, especially a method and system for real-time and dynamic adjustment of the furnace temperature of a heating furnace. Background technique [0002] The heating furnace is an important heat energy equipment in the steel rolling mill. Its function is mainly to heat the billet into a hot billet with uniform temperature, and can meet the requirements of high-quality rolling. With the continuous development of information technology, computer technology and network technology, the automation control level of steel rolling industry has also been continuously improved accordingly. [0003] At present, due to the increasingly fierce market competition, the product orders are becoming more and more small batches and changing specifications. The specifications of steel billets heated by the steel rolling heating furnace are changing more and more frequent...

Problems solved by technology

The above two methods are generally applicable to working conditions with a relatively stable production rhythm. Once the production rhythm fluctuates, the adjustment speed of steel temperature cannot keep up with the tapping speed. Using this technology alone cannot meet the needs of the project.
