Embodiment Construction

[0025] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention can be defined more clearly.

[0026] A packing belt, made of the following raw materials in parts by weight, including: Si: 1.4% to 2.0%, Fe: 0.2% to 0.4%, Cu: 0.15% to 0.48%, Mn: 0.55% to 1.15%, Zn: 0.15% to 0.45%, the balance is Al. The packing belt is made of aluminum, which belongs to the same aluminum product as the aluminum coil, and its composition is similar to that of aluminum alloy. It can be remelted along with the aluminum scrap, without special sorting out, which is conducive to repeated recycling, improves use efficiency, and saves resources. The strength of aluminum packing belt is higher than that of adhesive tape and canvas belt, and at the same time it has good toughness, which can effectively avoid ...

Abstract

The invention discloses a packing belt. The packing belt comprises the compositions of, by weight, 1.4-2.0% of Si, 0.2-0.4% of Fe, 0.15- 0.48% of Cu, 0.55-1.15% of Mn, 0.15-0.45% of Zn, and the balance Al. The invention further discloses a manufacturing process for producing the packing belt. The manufacturing process comprises the following steps that an aluminum alloy with the composition ratiois melt into aluminum liquid, and the aluminum liquid is filtered through a filter plate in multiple layers; the aluminum liquid is cast into an aluminum alloy ingot through a casting machine; segregation inclusions on the surface of the aluminum alloy ingot are milled by using a milling machine; the milled aluminum alloy ingot is placed in an environment with a heat preservation temperature of 500-600 DEG C for heat preservation, and the heat preservation time is 2 to 4 hours; an insulated aluminum alloy ingot is hot rolled into an aluminum alloy coil with a thickness of 4mm to 5mm; the aluminum alloy coil is cold rolled to a thickness of 0.65mm + / - 0.02 mm after multiple cold rolling; and the aluminum alloy coil is cut into packing belts by a slitting machine. The strength of the packingbelts is higher than the strength of adhesive tapes and canvas tapes, and at the same time, the packing belts have good toughness, and can effectively avoid the rebound phenomenon when in use.

Description

technical field [0001] The invention relates to the technical field of strapping manufacturing, in particular to a strapping and a manufacturing process for producing the annealed strapping. Background technique [0002] Aluminum ingots and alloys are melted at high temperature and casted into aluminum alloy flat ingots of 8 to 10 tons, hot rolled into aluminum coils, and then cold rolled to the specified thickness, followed by annealing and slitting to meet the requirements. strength and width. With the gradual processing and thinning of the aluminum coil, the strength and hardness of the metal material increase, and the aluminum coil is easy to loosen. Moreover, during the entire production process, aluminum coils have to be repeatedly transported and hoisted in the factory, and uncoiled and rewound on different machines and equipment. [0003] During the processing and transportation of aluminum coils, in order to prevent the aluminum coils from being uncoiled, the surf...
