Application and Related Equipment of H Beam Flange Straightening Machine
1) Origin: In the process of welding H Beam production, H Beam flanges usually generate deformation after SAW (Submerged arc welding) welding caused from heat input, which should be flattened in special purpose I H Beam Straightening Machine;
2) Working Process: By means of moving through I H Beam Flange Straightening Machine, flanges of the fabricated H Beam got flattened, and the entire piece of H Beam can be off line from H Beam Production Line as finished product for Steel Structure use;
3) Applicating Volume: Taking over 70%~ 80% applicating cases of I H Beam Straightening Machine, various forms of I H Beam Flange Straightening Machine is the largest selling volume product of its equipment category.
Based on H Beam position during straightening process, H Beam Straightening Machine can be divided into two general groups of:
1) Vertical orientation I H Beam Straightening Machine --- Account for over 90% of total share;
2) Horizontal Orientation I H Beam Straightening Machine --- Small percentage of actual use:
Going further, the Vertical orientation I H Beam Straightening Machine has 2 branches of motor drive and hydraulic drive:
1) Motor drive I H Beam Flange Straightening Machine is fitting for straightening conventional specifications of welding H Beam. It can straighten Q235-A carbon steel (Tensile strength 370~ 510 MPa) in the thickness range of 6~ 40mm;
2) Hydraulic drive belongs to heavy duty I H Beam Flange Straightening Machine. Its max. straightening capacity can be up to Q345-A carbon steel (Tensile strength 510~ 600 MPa) in the thickness range of 6~ 80mm;
3. In all, there is always the most fitting structure and specifications of I H Beam Flange Straightening Machine, which is applicable for every customer selection;
1) Differently, HJ series Horizontal Press I H Beam Longitudinal Straightening Machine is used for straightening deformation along the entire length of welding H Beam:

The Lefthand Scrolling Photos: From raw material to finished product of Wuxi JACK I H Beam Flange Straightening Machine
This is solid type straightening rollers, made of high strength alloy steel, precisely machined, and went thru strict control heat treatment to guarantee its mechanical performance.
There are 2 pairs of supporting rollers in the H Beam Straightening Machine, which holds H Beam in perfect vertical position in flexible way, guided precisely in bushing;
Assembly of Straightening Rollers, Supporting Rollers, Shaft Box, Slotting Table are all controlled in precise manner, with strict control tolerance.
Should meet below 3 pre-conditions of:
1) Max. straightening capacity of the I H Beam Straightening Machine;
2) Reasonable straightening efficiency that meets customer demand;
3) Suitable purchasing budget on I H Beam Flange Straightening Machine.
This is weighted on the basis of:
a) Max. thickness of H Beam flange --- 40/ 50/ 60/ 80 mm;
b) Carbon steel grade, or tensile strength --- 370/ 510/ 600 MPa;
Max. straightening capacity of each model Wuxi JACK I H Beam Straightening Machine are summarized in below table:
Model | Applicable Material | Max. Thickness |
HYJ40/ HYJ800 Mechanical drive Vertical Orientation H Beam Straightening Machine | Q235, Tensile Strength 370~510 MPa | 40 mm |
YTJ40/ 50/ 60/ 80 Hydraulic drive Vertical Orientation H Beam Straightening Machine | Q345, Tensile Strength 510~600 MPa | 40/ 50 /60 /80 mm |
WJ25/ 40 Hydraulic drive Horizontal Orientation H Beam Straightening Machine | Q235, Tensile Strength 370~510 MPa | 25/ 40 mm |
1) Accommodating H Beam Flange Width: The distance between the two pairs of rollers is also adjusted manually by means of handwheel;
2) Straightening Driving Force: The down pressing movement of the 2 pieces of upper straightening roller is driven with vertical mounted oil cylinders;
Here we take the most popular model: HYJ-800 vertical orientation motor drive H Beam Straightening Machine as an example:
1) As can be seen from the above 1st and 2nd photos, working on I H Beam Flange Straightening Machine is relatively simple;
2) The left and right 2 pieces of upper straightening rollers can be adjusted together, or one by one;
This mainly focus on physical modulation of below two points:
a) Span of the 2 pieces of upper position straightening rollers, to be fitting for different width of H Beam flange;
b) Downward stroke of the 2 pieces of upper position straightening rollers, based on thickness and deformation condition of H Beam flange;
4) Straightening Accuracy Management: These two adjustments can all be checked with measurement rulers installed at cavity of the I H Beam Straightening Machine, please check the 3rd photo;
5) Straightening Times: To straighten flanges deformation of welding H Beam, the workpiece H Beam needs to go through the vertical orientation I H Beam Flange Straightening Machine 2 times, 1 piece of flange to be straightened 1 time.
1) Rule of Thumb: In all the models of Wuxi JACK Vertical I H Beam Straightening Machine, there is relationship between thickness and width of flange available for straightening, which we give in manual book of each model;
2) For example, below is empirical Data on HYJ-800 Mechanical motor drive Vertical orientation I H Beam Straightening Machine:
