Specialty: Compared with the previous introduced product family of HYJ series motor drive and YTJ series hydraulic drive H Beam straightening equipment, the WJ series has different machine structure and workpiece orientation during straightening.
1. Common Point between WJ Series Horizontal H Beam Flange Straightening Machine and HYJ /YTJ Series Vertical type:
1) Application: Same as HYJ and YTJ series, WJ series machine is also used for straightening deformation of H Beam flange after Submerged Arc Welding;
2) Working Principle of WJ Horizontal H Beam Straightening Equipment:
WJ series machine also utilizes T cavity formed by the three pieces of straightening rollers, as in HYJ and YTJ models machines, to straighten the deformed flange. Here the difference is, in WJ series machine, H Beam is flipped 90° to make it "lying down":

3) Straightening Unit: Straightening rollers of WJ series straightening equipment are same as HYJ and YTJ series machine, in terms of material/ heat treatment/ hardness and service life;
4) Straightening Power Source: Same as YTJ series, the WJ series horizontal position straightening machine is also hydraulic drive for straightening stroke acting on the H Beam flange.
2. Difference between WJ Series Horizontal H Beam Flange Straightening Machine with HYJ and YTJ series Vertical Type:
1) Workpiece Position: The most conspicuous distinction with HYJ and YTJ H Beam Flange Straightening Machine is position of H Beam during working:
Comparison on H Beam orientations in vertical and horizontal H Beam Flange Straightening Machine: (Fig.2,3)
Vertical H Beam Horizontal H Beam
2) Working Unit in WJ Horizontal H Beam Straightening Machine:
Such structure of H Beam position allows for two pieces of T cavities mechanism to be arranged at both sides of H Beam flanges;
In other words, in WJ series horizontal straightening machine, both ends of the H Beam flange can be straightened at the same time;
3) Productivity of WJ Horizontal H I Beam Straightening Machine:
In this way, with the similar straightening speed of 6000mm/min. in HYJ and YTJ series machines, the WJ series horizontal straightening machine can straighten two flanges of H Beam simultaneously, doubling productivity of straightening process compared with HYJ and YTJ series;
4) Workpiece Size Applicable for WJ Series Horizontal H Beam Straightening Equipment:
a) The WJ models 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 ones;
b) For the H Beam size available for being straightened in WJ series machine, 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 WJ25 or WJ40 models machine;
b) And correspondingly two sets of related drive and transmission units;
c) As introduced, in HYJ and YTJ vertical structure H Beam Straightening Machine, there are in total one pair of straightening roller and one set of drive and transmission unit, in one set of the straightening machine;
6) Commercial Offer on WJ Horizontal H Beam Straightening Equipment:
a) One set of WJ25 horizontal structure straightening machine is about 60% higher than that of YTJ40 vertical structure;
b) The reason lies in the above mentioned two groups of straightening units (Including straightening rollers and transmission unit), compared with only one group in HYJ and YTJ series vertical structure machine. Correspondingly, the WJ series quotation and output rate are also obviously higher;
7) Application Proportion of WJ Horizontal I Beam Flange Straightening Machine:
a) On the other hand, as explained in the product section of “HYJ and YTJ series”, straightening process is not bottleneck in welding H Beam production on the aspect of manufacture velocity;
b) HYJ and YTJ series straightening machine already has throughput higher than that of H Beam Assembly and Tack Welding Machine, as well as 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 structure straightening machine takes minority (About 10%) of application after SAW welding;
d) For the detailed specification and structure of each model WJ series equipment, please check product section of WJ25 and “WJ40 hydraulic H Beam Straighten Machine”.
