Production process of high-strength iron sheet packing belt

Production process of high-strength iron sheet packing belt
　　 Use carbon-manganese steel hot-rolled coil as the material. The carbon-manganese steel contains the following components (weight percentage): C: 0.15～0.28%; Si: 0.005～0.07%; Mn: 1.20～1.70% ; P: 0.005～0.025%; S: 0.0005～0.015%; Als: 0.015～0.10%, the rest is Fe, the coil is slit, pickled and then cold rolled, and then the cold rolled iron sheet is sent to the strap Enter the continuous heating furnace to heat the iron strapping to 400～600℃. After the iron strapping is released, it will be cooled. The tensile strength of the high-strength packaging iron strapping is not less than 930MPa, and the elongation is not less than 8. %. High-strength packaging iron strapping not only has stable mechanical properties, it can meet the performance requirements of high-strength packaging iron strapping, and its manufacturing process can replace the traditional lead bath quenching heat treatment process when manufacturing high-strength packaging iron strapping, with low cost and No pollution.
　　High-strength packaging iron strapping characteristics:
　　 High-strength packaging iron sheet strapping is a carbon-manganese steel that mainly contains the following components: C: 0.15～0.28%; Si: 0.005～0.07%; Mn: 1.2～1.7%; P: 0.005～0.025%; S: 0.0005 to 0.015%; Als: 0.015 to 0.10%, the rest is Fe, and the percentage is by weight.
