摘　　要：研究了退火处理温度对无限冷硬铸铁轧辊组织和性能的影响。研究结果表明，温度低于600℃的热处理，对冷硬铸铁的宏观组织没有明显影响，但使其宏观和微观硬度降低。Influence of annealing temperature on structure and properties of infinitely chilled ductile cast iron roller is studied in the present research. The results demonstrate that temperature of annealing below 600℃ has little effect on the structure of infinitely chilled nodular iron roller but makes the macro-hardness and microhardness decase.
