Abstract: Due to harsh production environment and numerous coupling factors of control system, the process of heating furnace is always a weak link in the automation degree of production line, which affects the intelligent and digital process of production line. With the continuous update and development of big data technology, it has gradually entered the field of metallurgical industry, aiming at using data mining technology to establish data-driven mathematical models, so as to break through the bottleneck of traditional models. This paper introduces the construction of intelligent control system of heating furnace combustion based on big data platform in a certain scene. Big data algorithm is adopted to carry out intelligent optimization control for heating furnace combustion process, improve the control precision of heating furnace. The intelligent furnace temperature control boasts an online rate not less than 93% and discharge slab temperature control accuracy (±12 ℃) of 93.2%, while reducing fuel consumption of 3.5%,achieving energy savings and improve product quality.
