With the development of the steel structure market, the use of box beams in bridges, power stations, boilers, and high-rise buildings is increasing. Comparing from the stress point of view, the ratio of the torsional constant of the I-shaped interface and the box-shaped interface with the same cross-sectional area is about 1:500, and the ratio of the maximum torsional shear stress is approximately 30:1. And its "â–¡"-shaped cross-sectional form has high bending resistance under the action of bidirectional stress. In addition, from the overall stability, the box beam is also better than the I beam. Therefore, in a specific application, the box beam has its unique structural advantages, which can achieve better economic advantages.

Scope of application:
This production line is suitable for the production of high-strength box beam structures where the diameter of the ventilation holes on the partitions in the main column is small, and the four sides of the partitions must be welded. Including the prefabrication and assembly welding of the main box, the prefabricated installation of the internal partition, the external corbel, etc.
Features:
1. Good quality and high efficiency.
2. Through careful and meticulous technical preparation and design of special paired tires, errors can be well controlled and construction difficulty is reduced. At the same time, the adjustment process of the group alignment is reduced, which not only ensures the quality, but also greatly improves the production efficiency.
3. The separator is welded by electro-slag welding, which improves the production efficiency, reduces the production cost, and solves the problem of difficult welding of the internal separator.
