However, the method for obtaining the plasma heating efficiency of the tundish, because the heating parameters of the heating devices in different structures and in different environments are not the same, and the structural parameters of the tundish are also different. Therefore, the plasma heating efficiency of the tundish determined according to the reference temperature range, The accuracy rate is low, and the optimization of the tundish plasma heating process cannot be realized

Description
technical field [0001] The present invention relates to the technical field of plasma heating, and in particular, to a method, an apparatus, an electronic device and a computer-readable storage medium for obtaining the plasma heating efficiency of a tundish. Background technique [0002] Plasma heating technology is a technology that applies a certain amount of electric energy to the plasma generator to generate arc light to fully ionize the gas medium, so that the plasma energy is highly concentrated for heating. The tundish plasma heating is a heating that can compensate for the temperature drop in the tundish in time. The method is of great significance for stabilizing the temperature change in the tundish, realizing constant temperature pouring, and improving the quality of the slab. Among them, the operation economy of the tundish plasma heating needs to be evaluated by the tundish plasma heating efficiency. By evaluating the tundish plasma heating efficiency, the key p...
