Heat Transfer Analysis and Heat Transfer Coefficient Determination of Stainless Steel

摘要: 研究了非等温圆柱体热压时的传热规律,并计算出接触表面热传导系数值。在实验室,测定非变形压缩下的1Cr18Ni9Ti不锈钢试样若干点的温度,根据得到的数据分析工件导热特性,利用有限差分技术,确定热传导系数值。

Abstract: The heat transfer coefficient at the contacting surface of two specimen was calculated. In laboratory, the temperatures of some points on surface of 1Cr18Ni9Ti were measured under the condition of hot non-deforming press. From these data, the heat trans-fer characters of the speciman were analysed. By finite difference technique, the heat trans-fer coefficient of 1Cr18Ni9Ti stainless steel could be obtained.
