T-shaped steel manufacturing process

T-shaped steel is a common structural steel with a T-shaped cross-section. It is widely used in construction, bridges, machinery manufacturing and other fields. The following introduces the manufacturing process of T-shaped steel.

1. Raw material preparation: Generally, carbon structural steel is used as the main raw material of T-shaped steel. Steel needs to undergo quality testing to ensure that it meets the corresponding standard requirements.

2. Cutting: Cut the raw steel plates according to the required T-shaped steel specifications. First mark according to the design requirements, and then use a cutting machine or flame cutting machine to cut. Make sure the panels you cut are accurate to size.

3. Hot rolling: Put the blanked steel plate into the hot rolling mill for heating to make the steel plate reach the appropriate hot rolling temperature. The steel plate is then rolled into the required shape, that is, T-shaped, through the rolling of a hot rolling mill.

4. Cold rolling: Put the hot-rolled T-shaped steel into a cold rolling mill for cold rolling. Cold rolling can improve the surface quality of steel and reduce dimensional errors. At the same time, cold rolling can also improve the hardness and strength of steel.

5. Straightening: The cold-rolled T-shaped steel is straightened to ensure that its straightness and surface flatness meet the requirements. Straightening is usually performed using a hydraulic straightening machine.

6. Cutting: The straightened T-shaped steel is cut according to the required length. Cutting can be performed using equipment such as saws, cutters, wire cutters, etc.

7. Surface treatment: The cut T-shaped steel is surface treated to remove burrs, rust, etc. caused by cutting. Commonly used surface treatment methods include pickling, sand blasting, shot blasting, etc.

8. Inspection: Conduct quality inspection on the completed T-shaped steel to check whether its size, surface quality, mechanical properties, etc. comply with relevant standards.

9. Packaging and leaving the factory: The qualified T-shaped steel is packaged through packaging equipment and then shipped out of the factory for sale.

The above is a brief introduction to the manufacturing process of T-shaped steel. In actual production, process optimization and improvement also need to be carried out according to specific requirements to ensure that T-shaped steel products meet quality requirements.
