140 Tube Mill Machine Production Process
1. Feeding and Preprocessing: This step involves loading the raw material (usually steel coils) onto the machine and conducting necessary preprocessing, such as inspecting the size and quality of the steel coils.
2. Flattening and Cutting: In this step, the steel coils are flattened and cut into appropriate-sized steel strips as needed for the subsequent welding process.
3. Forming and Welding: The ERW tube mill uses high-frequency straight seam welding technology and forming machines to weld the steel strips into tube shapes, forming the required tubing.
4. Shaping and Straightening: After welding, the tubing may have some deviations in shape and size, so it needs to be adjusted through shaping and straightening processes to ensure it meets specifications.
5. Flying Saw Cutting: The welded and shaped tubing is cut to the desired lengths according to customer requirements, forming finished products.
6. Stacking and Packaging: The final step involves stacking and packaging the finished tubing using stacking machines or automatic packaging machines, and labeling them with relevant information for identification during transportation and use.
