Abstract

The invention belongs to the technical field of heating furnace combustion control and particularly provides a dynamic correction method and device of a heating furnace dual-crisscross amplitude limitsystem. During practical working, when temperature rising requirements of a heating furnace are given, the heating furnace automatically selects an amplitude limit correction factor Ki' under the corresponding state, then an original amplitude limit value Ki, the amplitude limit correction factor Ki' and an oxygen content correction factor m jointly act on an air conditioner, and the original amplitude limit value Ki and the amplitude limit correction factor Ki' jointly act on a coal gas regulator. Through the dynamic correction method and system, the demand for rapid temperature variation inthe heating furnace can be effectively met, the response speed of an original dual-crisscross amplitude limit system is greatly increased, temperature variation can be rapidly responded particularlywhen a heating load varies greatly, and a satisfactory heating furnace temperature control effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of combustion control of heating furnaces, and in particular relates to a dynamic correction method and device for a double-crossing limiter system of a heating furnace. Background technique [0002] The heating furnace is one of the important equipment in the metallurgical industry. Its function is to heat the billet to meet the requirements of subsequent rolling treatment. The performance of the heating furnace directly affects the rolling quality of the billet. The combustion atmosphere in the furnace, the temperature of the slab out of the furnace, the oxidation loss of the slab surface, the temperature uniformity of the slab and the gas consumption, etc., have always been important indicators to measure the steel burning performance of the heating furnace. These parameters are closely related to the combustion control system of the heating furnace. Therefore, the heating furnace The study of combustion ...
