The box beam can be used in high-rise and super high-rise buildings and large scale bridges etc. The box beam is generally rectangle or square because it consists of four plates which can form pipe bearing structure. The box beam has good rigidity, light weight, high intensity, so we can pour concrete into it, thus forming a special ring clamping concrete-steel column structure which has good axial load, bending moment bearing capacity, horizontal force bearing capacity. The box beam can also be equipped with additional baffle inside it.
The steel box beam welding line is the specific production line for box beam. It can carry out the full assembly line of box beam from cutting, box beam assembly, backing welding, electroslag welding, submerged arc welding, end face milling etc.
|Box beam width||300-1200mm|
|Welding speed||0.25-0.75 m/min (depending on welding technology)|
|Welding type||Fillet welding in downhand|
|Welding wire diameter||3.0-5.0mm|
|Control mode||Frequency conversion steeples speeding|
|SAW welding system||DC1000 *2sets, Lincoln USA/ MZ1000,China|
The steel box beam welding line has the following features
1. This welding line has the following equipment sets: steel box beam assembling machine, 180 degree steel beam overturn equipment, electroslag welding machine, submerged arc welding machine, end face milling machine etc. It can be used for box beam baffle assembly, U-type, box beam assembly, hydraulic overturn, electroslag welding, backing welding, submerged arc welding, end face milling etc.
2. Jinfeng has 13 CNC machining centers, 6 machining centers of more than 3 meters. The main machine rack is processed by the CNC machining center after being welded, thus ensuring the installation precision and service life of the machine.
3. Most of the quick-wear parts is processed by Jinfeng, so we have rich stock to ensure in-time after-service.
Jinfeng Welding & Cutting Machinery Manufacture Co., Ltd hires senior engineers from ESAB to lead mechanical department, electrical department and software department. There are 80 people in the team in total. They will carry out development and design of various structural steel H beam production lines, so that we have technical guarantee.
Jinfeng has strong production capacity: we have 13 imported CNC machining centers, 3 4mx12m large machining centers and 300 equipment sets such as CNC grinding machine, drilling machine and milling machine etc.
We also have specified hardware processing workshop, plate welding workshop, assembly shop, packaging shop, painting and drying shop etc.
The key part of the complete steel box beam welding line is rack assembly which is carried out by CNC machining center. Meanwhile, it can be multi-surface processed. So the installation precision and machine service life can be ensured.
