Abstract To realize controlled cooling of seamless tube between sizing and straightening in the production process of automatic plug mill, the laws of microstructural and mechanical properties change of rolled No.20 tube during the cooling process were investigated using numerical simulation method under the different cooling conditions. Firstly, after the cooling curves of steel probe in the different cooling mediums were measured, the relationship of heat transfer coefficient of probe and work piece’s temperature was obtained by programming and solution using the basic principle of inverse heat conduction method. And a predict system of temperature, phase transformation and mechanical properties in the cooling process of tube was established using finite difference method. The cooled phase and properties of tube were analyzed in the different cooling processes. Finally, the air cooling experiment of tubes was carried out and the temperatures at different time of cooling and mechanical properties of tubes were measured. The simulated results are in good agreement with the measured data. These works lay a foundation of controlled cooling of seamless tube.
