厚板在淬火过程中温度变化剧烈,且随着板厚的增加厚度方向的温差加大,极易导致表面和心部组织不均匀.本文利用ABAQUS软件对厚板淬火过程的温度场进行数值模拟,计算淬火过程钢板厚度方向的温度梯度和冷却速度,为制定合理的淬火工艺制度提供理论依据,以保证厚板淬火前后组织性能的均匀.
厚闆在淬火過程中溫度變化劇烈,且隨著闆厚的增加厚度方嚮的溫差加大,極易導緻錶麵和心部組織不均勻.本文利用ABAQUS軟件對厚闆淬火過程的溫度場進行數值模擬,計算淬火過程鋼闆厚度方嚮的溫度梯度和冷卻速度,為製定閤理的淬火工藝製度提供理論依據,以保證厚闆淬火前後組織性能的均勻.

There is a drastic temperature variety in plate during quenching process, and the difference in temperature in thickness direction increases with the increase of thickness. It may easily induce non-uniform microstructure in plate. The commercial software ABAUQS was used to simulate the temperature field in plate during the quenching process. The temperature gradient and cooling rate were calculated. A good theoretical reference was provided to establish reasonable quenching process schedule for the homogenous mierostructure and properties in plate.
