The Purpose of H Beam Straightening Machine

The Position and Function of H Beam Straightening Machine:

 

1. H Beam Straightening Machine is the 3rd set of core H Beam Production Machine in all types of H Beam Production Line, following H Beam Assembly Machine and H Beam Welding Machine. It is for straightening H Beam flange deformation or whole length curving after submerged arc welding;

2. The Usage of H Beam Straightening Machine is:

1) After the large current submerged arc welding performed at the previous station, flange of H Beam will have upturned deformation due to the effect of heat input, checking at cross section of the H Beam, which should be corrected for its performance;

2) Meanwhile, sometimes there is also certain degree of winding along length direction of H Beam, which should also be straightened in case of exceeding tolerance;

3. Straightening Capacity of H Beam Straightening Machine for Flange Deformation:

1) Based on driving mode and models of H Beam Flange Straightening Machine, the maximum flange thickness available for straightening can be up to 40mm, 50mm, 60mm, and 80mm;
2) The corresponding Chinese grade of H Beam carbon steel are Q235 (Tensile strength: 370~ 510 MPa) and Q345 (Tensile strength: 510~ 600 MPa).

The Classification of H Beam Straightening Machine

Concrete Types of H Beam Straightening Machine:

 
Correspondingly, there are series of H Beam Straightening Machine for straightening H Beam flange or whole length deformation, in different driving mode and working principle:
 

1. H Beam Flange Straightening Machine:

1) Main stream of H Beam Straightening Machine is for this purpose. So, in practical application, when people talking about “H Beam Straightening Machine”, they usually imply H Beam Flange Straightening Machine, unless otherwise specifically denote;
2) Based on orientation of H Beam during straightening, there are two types of H Beam Flange Straightening Machine: Vertical and horizontal. Please check below sketch:
