In the paper, the effect of cooling rate on microstructure and mechanical properties of steel tube after heat treatment furnace was studied by comparing the steel tube with air cooling and water cooling. The test results showed that accelerating the cooling rate of steel tube can increase the nucleation rate at the time of phase transformation and restrain the aggregation and growth of precipitation phase so as to achieve the purpose of grain refinement as well as improving microstructure and mechanical properties.

文章通过对出热处理炉后的钢管采用空冷和水冷的对比试验,研究了冷却速度对钢管组织结构及力学性能的影响。试验结果表明,加快钢管的冷却速度能够增加相变时的形核率、抑制析出相的聚集和长大,从而达到细化晶粒、改善组织、提高力学性能的目的。

文章通过对出热处理炉后的钢管采用空冷和水冷的对比试验,研究了冷却速度对钢管组织结构及力学性能的影响。试验结果表明,加快钢管的冷却速度能够增加相变时的形核率、抑制析出相的聚集和长大,从而达到细化晶粒、改善组织、提高力学性能的目的。

In the paper, the effect of cooling rate on microstructure and mechanical properties of steel tube after heat treatment furnace was studied by comparing the steel tube with air cooling and water cooling. The test results showed that accelerating the cooling rate of steel tube can increase the nucleation rate at the time of phase transformation and restrain the aggregation and growth of precipitation phase so as to achieve the purpose of grain refinement as well as improving microstructure and mechanical properties.
