Square bar, there is often wave-shaped edges, folding, pyramid and other defects. Its volume weight is heavier, the straight hair volume by the cutting head, tail after cutting, trimming and multi-pass straightening, leveling and other finishing line processing aluminum sales center, and then cutting board or heavy volume becomes: Hot rolled steel plate, hot-rolled coil leveling, slitting with other products. If the hot-rolled coil pickling finishing descaling and pickling hot rolled coil coating characteristics and uses of the main characteristics of precision aluminum side: Precision seamless aluminum square inner and outer wall oxide layer aluminum brand, under high pressure without leakage, high precision aluminum profile, high-quality finish, cold deformation, flaring, flattening no cracks no precision aluminum square bar main purposes: used in hydraulic systems with aluminum side, the car manufacturer with aluminum side, military, engineering machinery, railway locomotives, aerospace, shipbuilding, injection molding machines, die casting machines, machine tools, diesel, petrochemical, power plants, boilers, equipment and other industries. Aluminum rod production methods can be divided into two kinds of extrusion and rolling. Due to many different specifications, complex cross-sectional shape, size and surface demanding, so the vast majority extrusion methods. Only in the larger production volume. When using the rolling method dimensions and surface requirements of small and medium sizes lower rod. You can also stretch several times to get the appropriate sizes of aluminum rod. General use are ordinary extruder extrusion production of ordinary rod, with anti-extrusion production of hollow rods. Aluminum rod production process: first extrusion ingot heating → → → secondary extrusion artificial aging hardening → → → tension straightening roller straightening straightening → → hand-cut finished product inspection → → Print → storage. _ Aluminum Aluminum Supply cis (certified) _ Aluminum Aluminum Co. provided by Jinan rolls.
