【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。更多还原

【Abstract】 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.更多还原
