摘　　要：典型的空心锻件-电渣合金钢辊套锭重≥2 t,内孔直径560～880 mm,外径670～1200 mm,长1300～1780 mm。在保证质量的基础上,采用改进的工艺-直接锻粗法后,与传统工艺相比,可减少2道工序和一次中间加热,锻件成材率提高5%～15%,显著降低生产成本。Typical hollow forgings - electro-slag remelting （ESR） alloy steel roll sleeve with inner diameter 560 ～880 mm, outer diameter 670 ～ 1 200 mm and length 1 300 - 1 780 mm are usually produced by ≥2 t ingots. Based on the ensuring product quality, as compared with traditional forging process, it is available to decrease by 2 procedures and once reheating with using optimized process- direct forging upsetting. The forgings yield increased by 5% ～ 15% to obviously decrease production cost.
