1) In the process flow of welding H Beam Production Line, H Beam Straightening Machine is used for flattening upward bent flange after submerged arc welding, which is caused from heat input in the SAW process;
2) For this reason, the equipment is also named as H Beam Flange Straightening Machine;
It is the fourth set of core equipment in layout of H Beam Production Line, following:
1) CNC Strip Plate Cutting Machine;
2) H Beam Assembly and Tack Welding Machine;
3) H Beam Submerged Arc Welding Machine.
Based on laying orientation of H Beam during straightening, H Beam Straightening Machine has two general types of:
2. Using Volume Distribution on 2 Types: In most majority conditions, when mentioning on H Beam Straightening Machine, it refers to vertical standing equipment, which account for over 90% of practical application in H Beam Production Line.
For Vertical style H Beam Flange Straightening Machine, depending on its driving mode on straightening process, the equipment falls into two sub groups of:
1) Straightening Capacity: This series H Beam Flange Straightening Machine is for straightening H Beam flange with thickness up to 40mm;
2) The corresponding H Beam raw material grade is: Chinese carbon steel Q235, with its tensile strength in the range of 370~510MPa;
1) Straightening Capacity: This series H Beam Flange Straightening Machine is for straightening H Beam flange with thickness up to 40~ 80mm;
2) The corresponding H Beam raw material grade is: Chinese carbon steel Q345, tensile strength in the scope of 510~600MPa.
In practical application of H Beam Production Line, there are 2 types of important but not frequently used Hydraulic H Beam Straightening Machine:
1) Straightening Capacity: The max. H Beam flange thickness that can be straightened in such H Beam Straightening Machine has 2 grades: 25/ 40mm;
2) The corresponding H Beam raw material is Chinese carbon steel grade of Q235, tensile strength 370~510MPa;
3) Why Small Volume of This Machine: It has 50% higher quotation than HYJ and YTJ series Vertical orientation H Beam Straightening Machine;
1) Usage: There is another kind of HJ series Hydraulic H Beam Horizontal Straightening Machine, which is used for straightening the integral piece of H Beam deformation along its lengthwise direction, following H Beam Submerged Arc Welding Machine:
1) In all, models of high power H Beam Straightening Machine can be listed as below:
2) Note: Detailed introduction on each model of the equipment please refer to corresponding product section:
