Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The embodiment of the present invention discloses a rust-proof vacuum packaging method for a steel coil, comprising the following steps:

[0039] (1) After unrolling, observe whether the appearance of the steel coil is defective or damaged, and observe whether the plate head needs to be cut;

[0040] (2) Cut off the bad part of the board head and trim it with a cutting machine;

[0041] (3) Lift the roll to tigh...

Abstract

The invention provides a rust-proof vacuum packaging method for a steel coil, which belongs to the technical field of cold-rolled steel coils. In the traditional tubular film through-center sealing packaging process, the invention utilizes a sealing machine device and a vacuum sealing machine device to perform vacuuming and multi-region heat sealing treatment on the waterproof plastic film covering the steel roll, so as to realize the sealing of the steel roll. Vacuum packaging prevents air, water vapor, etc. from entering the coating film during storage and transportation in special environments (such as high-salt and high-humidity environments) for a long time, thus slowing or even eliminating rust on the surface of the steel coil. The packaging method of the invention is simple, low in energy consumption, low in cost, has good practicability, and has application potential in the field of packaging of cold-rolled steel coils.

Description

Technical field: [0001] The invention relates to the technical field of cold-rolled steel coils, in particular to a rust-proof vacuum packaging method for steel coils. Background technique [0002] The cold-rolled steel sheet will be used directly or as a basic coating after being prepared into coils. The surface quality and size of the sheet are required to be high, and this quality characteristic must be maintained until the final use. In this case, it is necessary to carry out protective packaging for the products during the storage and transportation of steel coils to overcome the rust-proof problem of the quality of the plate surface. [0003] At present, packaging technologies such as waterproof packaging (waterproof paper packaging, heat shrinkable film packaging), gas-phase anti-rust packaging (gas-phase anti-rust paper / film packaging), and dry air packaging (aluminum-plastic composite film + desiccant packaging) are mainly used at home and abroad. Packaging form, b...
