| Abstract: | It is introduced the process flow of 620 mm line and ultra - fast cooling equipments. After ultra - fast cooling used, by controlled cooling, the rolled Q235 slab can have the performance of Q345B, the cool- ing ability of strip steel can reach 230 ℃, the temperature difference along the whole rolling piece can be controlled within ＋ 15 ℃, and can meet utilization requirements for part of steel grades. At the same time the surface quality is better. |
