Hot Rolled Steel Sheet in Coil

1. Through the analysis of nano carbonitride particles precipitated in steel, the control method of steel structure and performance is mastered; according to the mechanism of metallurgical materials and engineering practice, combined with the relevant strength and toughness requirements of hot rolled steel sheet in coil.

2. Digest, absorb and innovate the imported production lines, and make full use of and give full play to the effectiveness of the imported technology

3. Strengthen the transformation of process equipment and establish Chinese characteristic technology

4. Focus on the research and development of cutting-edge technologies and strive to achieve independent innovation

5. Strengthen energy conservation and emission reduction to achieve green development

6. Break through the development bottleneck and realize automation technology

7. Strengthen technology integration efforts.

The steel produced by the steel mill is transported to the slab storage area by rail, controlled by computer technology → the slab is hoisted to the storage area by hoisting, then weighed and verified to ensure compliance with regulations, and then sent to the heating furnace for heating → after heating, the slab is transported by the conveyor rail, treated by the high-pressure water descaling device, and sent to the fixed width press for side pressing and width setting. According to the use requirements, it is then sent to the controllable rough rolling mill for rolling, and the intermediate slab with a thickness of 3 cm to 6 cm is made according to production needs → the intermediate slab is transported to the finishing mill for rolling to become a finished hot rolled steel sheet in coil.

During the entire hot rolled steel coil A516 process, from the slab entering the slab storage area to the final product shipment, it is controlled by the rolling line material tracking system and the dual warehouse management system.
