Abstract

The invention discloses a decorative bundling belt with the tensile strength of more than or equal to 950MPa. The decorative bundling belt comprises the following components in percentage by weight: 0.08-0.18% of C, 0.60-1.20% of Mn, less than or equal to 0.010% of Si, less than or equal to 0.010% of P, less than or equal to 0.010% of S, 0.30-0.60% of Nb, 0.30-0.60% of Cr and 0.040-0.070% of Als. The production steps comprise smelting, continuous casting for forming a blank, conventional casting blank heating, hot rolling, conventional acid washing, secondary cold rolling, secondary annealing and belt making. The thickness of the bundling belt is 0.8mm, the tensile strength is not less than 950MPa, the elongation is not less than 10%, the repeated bending times is not less than 10 times (R=5mm), and a uniform, compact, strong-adhesion and bright coating with the thickness of 1.5-2.5mu m is produced on the surface of the bundling belt. The bundling belt, which is not obviously rusted when being placed in an indoor atmospheric environment for 240 days, completely meets the requirements for bundling and packing high-quality commodities.

Description

technical field [0001] The invention relates to a strap and a production method thereof, in particular to a decorative strap with a tensile strength ≥ 950 MPa and a production method thereof. Background technique [0002] High-strength decorative strapping is a cold-rolled deep-processed product with high added value and broad market prospects. It is mainly used for bundling and packaging of high-quality goods. With the help of beautiful appearance, it can enhance the overall aesthetics of the product. [0003] At present, because the surface quality of blued or painted straps is not very high, they are mainly used for bundling ordinary goods, and it is difficult to play a good decorative role and cannot improve the grade. In contrast, colored coated straps are more suitable for decoration. [0004] Generally speaking, there are two main base materials for decorative strapping: cold-rolled sheet and hot-dip galvanized sheet. Ordinary cold-rolled sheet is relatively low in ...
