Large H-beam

Large H-beam

　　....H-beams are produced using the most economically efficient process of rolling cast special-shaped billets, along with a rational mill layout and the world's first optimized H-beam sawing production technology. Advanced high-precision techniques such as low-tension control, dynamic axial adjustment of rolls, and automatic roll gap control ensure product quality. ....The H-beam production process employs a high-performance and reliable stepping-type heating furnace; a reversible two-high blooming mill with large-stroke roll gap adjustment; a universal rolling mill equipped with AGC (Automatic Gauge Control) roll gap automatic control system and quick roll change device; and world-leading computer network technology that integrates three-level automated control into one system. ....H-beams feature wide flanges, high lateral stiffness, strong bending resistance, and parallel flange surfaces, making their connection structure more convenient and easier to implement compared to I-beams. They are simpler to cut, assemble, and process into other recycled materials. The cross-sectional design of H-beams is more rational than that of ordinary I-beams, enabling a 10–15% saving in metal when bearing the same cross-sectional load. They are widely used in steel structures for industrial and civil buildings, support frames for industrial steel structures, equipment steel frames in petrochemical plants, main plant and boiler steel frames in thermal power generation, components of railway and highway steel bridges, steel piles and support structures for underground projects, and frameworks for light and heavy machinery.
