Department of Metallurgical Technology, Central Iron and Steel Research Institute, Beijing 100081, China; 2. New Metallurgy Hi-Tech Group Co., Ltd., Beijing 100081, China) Abstract ： The process of producing heavy ingots was reviewed, including electroslag remelting, electroslag welding, electroslag casting and electroslag hot-topping, and the four methods mentioned above were contrasted from ingots quality, energy conservation and factory cost. The results show that the heavy ingots produced by electroslag remelting have high purity, homogeneous structure and better product quality compared with the other three methods. While, the energy consume and cost of electroslag welding, electroslag casting and electroslag hot-topping is lower and the equipment is simple. Key words ： heavy ingots; elect
