1) H Beam Straightening Machine is the third set of core H Beam Production Machine in the process route of welding H Beam production, also the last set;
2) The other two types of critical H Beam Production Machine preceding the H Beam Straightening Machine are H Beam Assembly and Tack Welding Machine, as well as H Beam Submerged Arc Welding Machine;
3) I Beam Straightening Machine (Here I Beam has the same meaning as H Beam) is used for straightening H Beam flange deformation, caused from heat input from H Beam submerged arc welding;
4) Below is straightening principle implemented in H Beam Flange Straightening Machine:
a) Vertical Orientation (This refers to Flange of H Beam is in the position of “Standing”, please check below sketch) H Beam Straightening Machine;
b) Horizontal Orientation (This refers to Flange of H Beam is in the position of “Lying Down”, please check below sketch) H Beam Straightening Machine;
2) And in most majority conditions when referring to this Automatic H Beam Straightening Machine, it refers to vertical standing H Beam Straightening Machine, accounting for over 90% of practical application.
For Vertical type H Beam Flange Straightening Machine, depending on its driving mode on straightening process, the H Beam Straightening Machine falls into two sub groups of:
Such mode of H Beam Flange Straightening Machine is for straightening flange thickness up to 40mm (For Chinese carbon steel grade of Q235, tensile strength in the range of 370~510MPa);
Depending on specific models, such mode of H Beam Flange Straightening Machine is for straightening flange thickness up to 40~ 80mm (For Chinese carbon steel grade of Q345, tensile strength in the scope of 510~600MPa).
a) The max. flange thickness that can be straightened in Horizontal H Beam Straightening Machine is 40mm, for Chinese carbon steel grade of Q235, tensile strength 370~510MPa;
b) And as mentioned previously, this type of high speed H Beam Straightening Machine does not have large volume application. The reason is, it has 50% higher machine price than HYJ and YTJ series Vertical orientation H Beam Straightening Machine;
There is another kind of HJ series H Beam Lengthways Straightening Machine, which is for straightening H Beam deformation along its lengthwise direction, after H Beam Submerged Arc Welding Machine:
In All, models of high power H Beam Straightening Machine is listed as below: (Note: Detailed introduction on each of the model I Beam Straightening Machine please refer to corresponding product section):
