Description

technical field

[0001] The invention belongs to the technical field of automatic control of LF furnaces, and in particular provides a double-station LF furnace molten steel temperature forecast control system. Background technique

[0002] As the link between steelmaking and continuous casting, the refining production of LF furnace is very important for adjusting the temperature and composition of molten steel and ensuring the smooth progress of continuous casting. The secondary system of the LF furnace takes the mathematical module as the core, conducts reasonable optimization calculations on operating parameters such as power supply, slagging, tempering and alloying, and conducts on-line tracking, forecasting and control of the temperature and composition of molten steel during the refining process. The smelting process of LF furnace is complex and changeable, and the automation level is limited, which limits the automatic control of LF furnace production. The automation ...
