Compared with the previous introduced product family of HYJ and YTJ mechanical and hydraulic H Beam straightening equipment, the WJ series has common point and difference listed as below:
1. Common Point between WJ Series Horizontal H Beam Flange Straightening Machine with HYJ and YTJ Series Vertical type:
1) Use of the WJ Horizontal I Beam Straightening Machine:
Same as HYJ and YTJ series, WJ series product is also used for straightening deformation of flange after Submerged Arc Welding;
2) Working Principle of the WJ Horizontal H Beam Straightening Equipment:
WJ series hydraulic horizontal H Beam straightening machine also utilizes T cavity formed by the three pieces of straightening rollers as in HYJ and YTJ to straighten the deformed flange, but flipped 90°:

3) Straightening Unit of the WJ Horizontal I Beam Flange Straightening Machine:
Straightening rollers of WJ series hydraulic horizontal H Beam straightening equipment are same as HYJ and YTJ, in terms of material/ heat treatment/ hardness and service life;
4) Straightening Power Source of the WJ Horizontal H Beam Flange Straightening Machine:
Same as YTJ series, the WJ series horizontal H Beam Flange Straightening Machine is also hydraulic driven for straightening the flange.
2. Difference between WJ Series Horizontal H Beam Flange Straightening Machine with HYJ and YTJ series Vertical type:
1) Workpiece Position in WJ Horizontal I Beam Straightening Machine:
The most conspicuous distinction with HYJ and YTJ H Beam Flange Straightening Machine is position of H Beam during working:
This is the reason the WJ series is named as hydraulic Horizontal H Beam Straightening Machine:

Vertical H Beam Horizontal H Beam
2) Working Unit in WJ Horizontal H Beam Straightening Machine:
Such kind of H Beam position allows for two T cavities arranged at both sides flanges;
In other words, in WJ horizontal I Beam Flange Straightening Machine, both ends of H Beam flange are straightened at the same time;
3) Productivity of WJ Horizontal I Beam Straightening Machine:
Which means, with the similar straightening speed of 6m/min. in HYJ and YTJ series, the WJ series Horizontal H Beam Straightening Machine can straighten two flanges of H Beam simultaneously, doubling productivity of straightening process compared with HYJ and YTJ series vertical position I Beam Flange Straightening Machine;
4) Workpiece Size in WJ Horizontal H Beam Straightening Equipment:
a) The WJ machine is for straightening H Beam of small and medium size, not the large and heavy duty ones that can be straightened with YTJ-60/80 heavy duty H Beam Straightening Machine;
b) For the H Beam size available for being straightened in WJ-series, and comparison with YTJ series, is discussed in product section of “WJ25 Horizontal H Beam Straightening Machine”;
5) Structure of WJ series Horizontal H Beam Straightening Machine:
a) There are two pairs of straightening rollers (Three pieces of straightening roller in each pair) equipped with one set of WJ-25/40 hydraulic Horizontal I Beam Flange Straightening Machine;
b) And two sets of corresponding drive and transmission units;
c) As introduced, in HYJ and YTJ vertical H Beam Straightening Machine, there are altogether one pair of straightening roller and one set of drive and transmission unit with one machine;
6) Price of WJ Horizontal H Beam Straightening Equipment:
a) One set of WJ25 Horizontal H Beam flange Straightening Machine is about 60% higher than that of YTJ40 vertical type;
b) The reason lies in the above mentioned two sets of straightening units (Including straightening rollers and transmission unit) compared with one set in HYJ and YTJ vertical H Beam Straightening Equipment, and hence higher output rate;
7) Usage Proportion of WJ Horizontal I Beam Flange Straightening Machine:
a) On the other hand, as explained in the product section of “HYJ and YTJ H Beam Straightening Machine”, straightening process is not bottleneck in welding H Beam production on the aspect of manufacture velocity;
b) HYJ and YTJ series H Beam Flange Straightening Machine already has throughput higher than that of H Beam Assembly and Tack Weld Machine, and H Beam Submerged Arc Welding Machine. Which means it can catch up TAKT of welding H Beam production;
c) This is another reason (together with its H Beam size) the WJ series Horizontal H Beam Straightening Machine takes minority (About 10%) of application on H Beam straightening after SAW welding;
d) For the detailed specification and structure of each model WJ series, please check product section of WJ25 and “WJ40 hydraulic H Beam straighten equipment”.
