复合孕育金属型可锻铸铁低温退火研究

Research on the Low temperature Annealing of Multiple Inoculated Permanent Mould Cast Malleable Iron

研究了复合孕育金属型白口铸铁在共析温度附近的低温退火工艺。试验结果表明，在共析温度（７６０℃）以下可以达到在一个阶段内完全铁素体化的技术要求。

The process of low temperature annealing of multiple inoculatied permanent mould cast white cast iron has been studied in this paper. Results show that the multiple inoculated permanent mould cast white cast iron can finish graphitization annealing at temperature below eutectic point (760℃).
