High-frequency welded H-beam production line - medium-sized

The main technical principle in high-frequency welded H-beam production is to use high-frequency current to directly heat the upper and lower flanges and web through the welding head contact, causing the base material to fuse, and then welding it into shape through a pressure welding roller. Heating is concentrated in the welding area, the heat-affected zone is small, and no welding rods or fluxes are used in the welding process. Therefore, the H-beams produced have flat flanges, high precision, and a beautiful appearance.

    The main technical principle in the high-frequency welding of H-beams is to use high-frequency current to directly heat the upper and lower flange plates and web plates at the welding joint, causing the base material to fuse. Then, it is formed by pressure welding rollers. Heating is concentrated at the welding point, the heat-affected zone is small, and no welding rods or fluxes are used in the welding process. Therefore, the H-beam produced has flat flanges, high precision, and a beautiful appearance.

    The slit coil is transported from the coil storage area to the coil carriage. This coil is sent to the center position of the decoiler by an electric-powered coil carriage. The coil is loaded onto the decoiler by expanding it with a hydraulic power shaft. The coil head flattening machine flattens the coil head, making it easy to be gripped by the gripping roller and fed into the straightening machine.

    The shearing and butt welding machine is a single-blade hydraulic shear, with each pair of scissors usable on four sides. A trolley-type scrap bin is used to receive the sheared head and tail ends. The inlet and outlet pressure plates use hydraulic clamping to clamp the tail and head, and can move in and out separately to adjust the welding gap to achieve optimal requirements. The welding torch is fixed on a base driven by a DC motor, moves at a set speed, and performs welding on the weld seam. The welding is performed by a CO2 gas shielded welding machine with automatic/manual welding operation. The guide rollers use a combination of manual adjustment and hydraulic drive, allowing for quick opening and centering, and have a function to adjust for lateral misalignment of the weld seam.

    The steel strip after shearing and butt welding is fed to the steel strip combination feeding rollers (for the flanges) and the outlet feeding roller device (for the web) via the inlet feeding roller device. The speed of the inlet and outlet feeding rollers is adjusted by a hanging tension control device. At the same time, after passing through the torsion frame and a long S-shaped bend, the web plate enters the steel strip combination feeding roller device together with the upper and lower flanges. The top flange is rotated to form a straight line with the cut, and the edges of the top and bottom flange plates and three-phase clamping roller flange plates are smoothed by the edge adjustment device.

    Three sets of steel strips are fed into the welding device. After the web plate is thickened, it enters the welding area with the flange plates. At the welding point, two extrusion rollers provide appropriate extrusion pressure. Welding is carried out under the voltage and current that meet the optimal welding requirements.

    Two solid-state high-frequency contact welding machines weld the three strips together. The welded H-beam is pulled out by three pulling frames and sent to the cooling area. The flange plates are straightened by the flange straightening frame.

    The H-beam flying saw cuts the steel beam into the required fixed length, and the cut steel beam is transported to the material platform.
