Correction of GB/T1591 Q345B I beam steel deformation

In recent years, with the rapid development of science and technology, GB/T1591 Q345B I beam steel has been widely used in industrial and civil buildings because of GB/T1591 Q345B I beam steel advantages of shorter construction period, simpler structure and better economic appearance than concrete structure.
According to the statistics, the number of scrapped components is as high as 7 because the welding deformation of large GB/T1591 Q345B I beam steel can not be corrected.

The correction of GB/T1591 Q345B I beam steel is the necessary order in the process of I beam steel manufacture. At present, there are two kinds of orthopaedic methods:
One is mechanical correction, the other is flame correction. For mass GB/T1591 Q345B I beam steel welding, the flame correction method is of high cost and low efficiency, and the technical experience level of workers is high. Therefore, mechanical correction method is widely used in manufacturing units.

There are two kinds of GB/T1591 Q345B I beam steel mechanical correction methods, one is the high power flange straightening machine correction method, the other is the large tonnage press combined with tooling method, which is referred to as the tooling pressure method. The flange straightening machine has more limitation. Currently, all kinds of flange straightening aircraft made in China were only suitable for GB/T1591 Q345B I beam steel with flange width B > 200mm, and GB/T1591 Q345B I beam steel with flange width B ≤ 200m could only be used by tooling pressure method.

Katalor has rich experience in GB/T1591 Q345B I beam steel, we have professioanl team to produce GB/T1591 Q345B I beam steel. So you can contact us freely if you have any need in GB/T1591 Q345B I beam steel. We will give you the best price.
