Abstract：The quality and service performance of large cold roll produced by electroslag remelting (ESR) ingot can be obviously improved. Based on the completely research of electroslag remelting process in 10 ton large ESR furnace, the advanced technologies taking descending power model as the core were developed, including ingot crystallization quality control, slag crust thickness control and hydrogen pickup prevention. Adopting these technologies, the remelting power consumption is up to 1400 kWh/t steel, the product quality is stable and its performance index can reach the enterprise standards higher than the national standards.
