Automatical HF welded H beam line

Light H-beam production line With light weight, good stiffness, high accuracy, aesthetic appearance, rapid constructing etc. features, high-frequency welded light H-beam is a high efficiency, economical and wide range useful engineering material, consistent with scientific development concept. The light H-beam production line is designed to manufacture welded light H-beam, used two major characteristics of high-frequency current: skin effect and proximity effect, placed two touch head in the lowest impedance path of the welding materials, all current flowed through the V-opening formed by the flange and the web plate, so that the welding power relatively comparatively concentrated on V-opening, less welding power to achieve the H-beam welding Features of high-frequency welded light H-beam production line: 1. High speed welding, high degree automation 2. Excellent performance section, various specifications 3. Small heat-affected zone, small internal stress, good forming effect 4. Uniform microstructure at welded place, material organization of web plate and flange evenly dissolved 5. High-frequency continuous welding substituted submerged-arc welding, without welding accessories, greatly reduced the manufacturing cost, the production efficiency enhanced several times The steps in the production of H-beam are continuously processed with high production efficiency: Feeding car → Uncoiler → Pinch roll and leveler → Shear and butt welder → Accumulator → Pulling out device→ Synchronized control → Stand → HF welder → Flange straightening device → Cooling system →Pulling out device → Flying saw → Output device → Discharging deviceMajor product specifications:Section height100 600 mmFlange width75 300 mmWeb plate thickness3 9 mmFlange thickness4 12 mmComputerized length6 15 mInstalled capacity2,300 KWCapacityEvery year 70,000 tonsRaw materials: plain carbon steel, high-quality carbon steel and low alloy steel (refractory weathering steel) If you are interested to know more, please feel free to contact us!
