What is the reason why the steel bar straightener can't straighten the steel bar?

If the wire rod adjusted by the straightener is not straight, the straightening block or the straightening wheel is improperly adjusted, so slow bending will occur. At this time, it is necessary to increase the fluctuation of the wire rod under the straightening wheel. If there are small twists and turns continuously, it is necessary to reduce the fluctuation of the wire rod under the straightening wheel.

Preventive measures and disposal methods:

1. performance

There are one or more "slow bends" along the steel bar.

2. Cause analysis

Each batch of materials has slow bending performance and belongs to the normal field.

3. Preventive measures

Reduce the zigzag degree of the strip.

4. Management measures

Steel bars with diameters below 14mm and 14mm shall be straightened by a steel bar straightener; Manual straightening of coarse steel bars: under the operating condition that the process can make the steel bars shape, put the elbow between the upper plate of the chuck and the column, straighten the elbow of the steel bar with a flat-head wrench, and straighten it with a sledgehammer if necessary; Cold work the steel bar to make it straight.
