Application of metal band saws in steel structure manufacturing

With the continuous development of modern industry, steel structures have been widely used in the fields of construction, bridges, machinery manufacturing, etc. As one of the indispensable equipment in the steel structure manufacturing process, the application of metal band saws has received more and more attention.

Application scenarios

Steel structure manufacturing involves the processing of a large number of high-strength steel materials. Metal band saws have become key productivity tools in the following application scenarios:

1.Cutting of large load-bearing components

H-shaped steel and I-beam cutting:For Q355B, S355JR and other construction steels, metal band saws can cut profiles up to 30 meters in length and 500 mm in thickness at one time, with an end surface roughness of Ra12.5μm, directly meeting the assembly requirements of high-strength bolt connections (HSFG).

Box beam forming:In the Shenzhen Ping An Financial Center project, the double-column band saw completed the cutting of box-shaped steel beams with a cross-section of 800mm*400mm, which is 4 times more efficient than traditional flame cutting and has no thermal deformation problems.

2. Complex node processing
Space grid nodes: Multi-angle bevel cutting is achieved through CNC programming. For example, in the steel structure node processing of the Beijing Daxing Airport terminal, the band saw machine shortened the traditional 72-hour processing cycle to 20 hours, and the accuracy error was controlled within ±0.3mm.
Special-shaped connecting plates: The band saw machine equipped with a laser positioning system can cut steel plates with a thickness of 10-100mm for making arc-shaped truss connectors, and the material utilization rate is increased to 98%.

3. Modular building prefabricated parts production
Standard component batch processing: The fully automatic band saw cluster can continuously cut 120 C-shaped steels (160mm×60mm×20mm) per hour, with an accuracy error of ±0.2mm, supporting rapid assembly construction.
Ultra-thick steel plate processing: During the construction of the Shanghai Tower, the band saw successfully cut 150mm thick Q460GJD steel plates with a sawing seam of only 1.8mm, saving more than 2 million yuan in material costs.
