【Abstract】 Tundish plasma heating technology could reduce the tapping temperature and superheat fluctuation range, as well as improve the quality of casting billets, whose equipment has the advantages of easy installation, high heating efficiency, and low energy consumption. Focusing on the hot issues related to tundish plasma heating technology, the equipment characteristics were systematically described, the application progress of plasma heating technology in slab production was introduced, and the metallurgical effects of plasma heating technology in practical applications were analyzed. The effect of the device on the temperature, chemical composition, and inclusion removal in molten steel was revealed. It is demonstrated that the first domestically developed new hollow graphite electrode heating device has achieved a breakthrough in tundish heating technology. It effectively meets the production requirements of low-, medium-, and high-carbon steels, offering an effective solution to the problem of temperature heat loss in the tundish, and achieving the goal of energy-saving and consumption reduction.更多还原
