Product Description

The flange plate of the H-beam (I-beam) after being welded by the gantry submerged arc welding machine will bend due to the effect of thermal expansion and cold contraction.

The H-beam flange straightening machine is used to correct and straighten the deformation of the H-beam after welding.

Lemar's hydraulic straighteners are different from other manufacturers:
 

1. The hydraulic straightening machine for H-beam flange plate is more than 3 tons heavier than the same model from other manufacturers.                        

2. The I-shaped steel straightening machine is suitable for the width of the flange plate 200-1500mm, and other manufacturers are 200-800mm.

3. The diameter of the correction shaft is 160mm, and that of other manufacturers is 130mm

4.The input and output roller table length of our 80mm flange plate thickness steel structure flange plate hydraulic straightening machine is 9 meters, and other manufacturers are 6 meters 

5.The speed of the straightening machine is about 9m/min, while other manufacturers are only 6.5m/min.

6.The web support wheel of our hydraulic straightening machine is propelled by a hydraulic cylinder, and the flexible clamping is not easy to damage the roller, while other manufacturers support it manually, which is very easy to damage the roller.

FAQ:

Q1. How to choose H-beam flange plate hydraulic straightening machine and H-beam flange plate mechanical straightening machine?

H-beam flange plate mechanical straightening machine is more used for light steel structure, the thickness of flange plate is less than or equal to 40mm.
Hydraulic straightening machine is more used for heavy steel structure. When the flange plate of H-beam is ≥40mm, it is recommended to choose a hydraulic flange plate straightening machine, which can obtain higher work efficiency

Q2. What is the structure of the flange plate straightening machine?
Steel structure flange straightener is mainly composed of base, upper frame, upper correcting wheel mechanism, web guide mechanism, upper frame moving device, main drive, conveying roller table, and electric control system.
It has the advantages of compact structure, convenient operation and easy maintenance.

Q3. How long is the warranty period of the machine? After the warranty period, how can the product be repaired?
Our machines are very strong and many customers have used them for more than 10 years.
The warranty period of the H-beam flange plate straightening machine is one year.
We permanently provide free technical support, after the warranty period, customers only need to pay the cost of the parts that need to be replaced.

Q4: What are the random documents shipped?
Including packing list, commercial invoice, bill of lading and other proofs required by customers.
