45 # cold drawn round steelThe processing technology

Cold drawn round steelIt is the use of cold drawing technology to process round steel, forcibly stretching and deforming it to achieve the goal of improving diameter accuracy and surface quality. The processing technology of cold drawn round steel generally includes the following steps:

1. Material preparation. The selected materials should comply with relevant standards, with excellent material requirements and no obvious defects such as cracks or heat treatment damage.

2. Pre processing. Usually, the steel billet is rolled into small round steel using hot rolling or cold rolling methods, and the billet needs to be cut and polished before further processing.

3. Cold drawing processing. After multiple cold drawing processes, the diameter and length of the round steel are gradually reduced to achieve the required working size.

4. Annealing treatment. In order to remove residual stresses generated during the cold drawing process and improve the toughness of the material, annealing treatment is required for cold drawn round steel.

2、 How to straighten cold drawn round steel effectively

Cold drawn round steel often undergoes bending and twisting during the processing, which affects machining accuracy and operational efficiency. So, how can cold drawn round steel be straightened?

Here are some commonly used methods:

1. Tensile effect straightening method. Clamp the cold drawn round steel onto the tensile machine, gradually straighten the steel with the force of the tensile machine, and measure the length and diameter accuracy after stretching with tools such as a tape measure. Stop stretching after reaching the desired size.

2. Squeezing effect straight method. Place the round steel in the extruder and use the high pressure of the extruder to extrude the round steel into the desired size and curvature.

3. Impact effect direct method. Using a specialized impact straightening machine, when bending and twisting occur on the surface of round steel, it is straightened through the impact effect.
