PROCESS FOR PRODUCING NON QUENCHED AND TEMPERED STEEL |
| 摘要 |
A process for producing a non quenched and tempered steel. The process comprises a cooling step at least after a finish rolling step. In said cooling step, an intense cooling and a moderate cooling are carried out alternately to allow the steel to undergo at least two stages of water cooling, so that the core temperature and the surface temperature of the steel become the same within a specified time, and thus ensures the uniformity of the mechanical properties of the steel and improves the production efficiency. |

1. A process for producing non quenched and tempered steel, comprising a cooling step at least carried out after a finishing step, characterized in that:
in said cooling step, an intense cooling and a moderate cooling are carried out alternately to allow the steel to undergo at least two stages of water cooling, so that the core temperature and the surface temperature of the steel become the same within a specified time. |
