Description
technical field [0001] The invention relates to an interface temperature drop prediction system in the iron and steel industry, and more specifically relates to an online prediction system and a prediction method for the temperature drop of molten steel at the steel casting interface. Background technique [0002] Modern steelmaking is centered on continuous casting. The traditional process of setting the tapping temperature is as follows: the continuous casting station formulates the converter according to the liquidus temperature of different steel types, as well as the state of production and equipment, and rigidly superimposes the estimated value of the temperature drop in different processes. Or the tapping temperature of the molten steel in the electric furnace. For the stability and continuity of production, the tapping temperature is generally set high, and the energy cost accounts for about 30% of the steel manufacturing cost, especially in the smelting area. Reduci...
