The result shows that the RE make CCT curve move towards right and hardness of steel increases at same rateofcooling.
结果表明：稀土使钢的过冷奥氏体转变曲线右移，在同样冷却速度下，加稀土钢的硬度增加。

The operation consists of reheating quench-hardened steel to some temperature below the critical range followed by any rateofcooling.
回火作业包括将淬硬钢重新加热到低于临界范围的某一温度然后以任意速率冷却。

The cooling water network of a plant was analyzed with the two methods, and the minimal flow rateofcooling water was determined under different circumstances.
