The production of L-shaped steel usually goes through the following main process steps:
1. Raw material preparation: Select high-quality steel as raw material and cut it into billets of appropriate size according to product specifications.
2. Hot rolling pre-processing: The steel billet is heated to reach a suitable plastic temperature for subsequent forming processing.
3. Forming processing: The heated steel billet is formed by rolling machinery and pressed into an L-shaped steel profile with an "L" shaped cross-section. This step usually includes rough rolling and finishing rolling.
4. Cooling treatment: Perform appropriate cooling treatment on the formed L-shaped steel to stabilize its internal structure and ensure product quality.
5. Shaping and grinding: Shape and grind the cooled L-shaped steel to make it meet the specified size and surface flatness requirements.
6. Surface treatment: As needed, surface treatment is performed on the L-shaped steel, such as spray painting, galvanizing, etc., to increase its corrosion resistance and aesthetics.
7. Quality inspection: Conduct quality inspection on the finished L-shaped steel, including appearance quality, dimensional deviation, mechanical properties, etc., to ensure that the product meets standard requirements.
8. Packaging and transportation: L-shaped steel that meets the standards is packaged, stored and transported in a prescribed manner to ensure that the product is not damaged during transportation.
The above is the general L-shaped steel production process flow. Each step is crucial and affects the quality and performance of the final product.
