Manufacturing process of GB/T1591 Q345B steel plate

Smelting and continuous casting: Q345B steel plate requires converter smelting and continuous casting processes during the manufacturing process. These processes can ensure the purity and quality of molten steel, thereby ensuring the performance and quality of steel plates.

Rolling and heat treatment: After continuous casting is completed, Q345B steel plate needs to be rolled and heat treated. Rolling can adjust the thickness, width and other parameters of the steel plate, and heat treatment can improve the mechanical properties and processing performance of the steel plate. During rolling and heat treatment, process parameters need to be strictly controlled to ensure the dimensional accuracy and surface quality of the steel plate.

Cutting and welding: During the manufacturing process, Q345B steel plates need to be cut and welded. Cutting can use mechanical cutting, flame cutting and other methods, and welding can use arc welding, gas shielded welding and other processes. These processes ensure the accuracy and integrity of the steel plate.
