Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] The embodiment of the present invention discloses a steel coil rust-proof vacuum packaging method, which includes 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 tighten the head of the b...

Abstract

The invention provides a rust-proof vacuum packaging method for a steel coil, and belongs to the technical field of cold-rolled steel coils. In a traditional barrel-shaped film core-penetrating type sealing packaging process, a sealing machine device and a vacuumizing sealing machine device are used for conducting vacuumizing and multi-area heat sealing treatment on a waterproof plastic film wrapping a steel coil winding drum, vacuum packaging of a steel coil is achieved, and air, water vapor and the like are prevented from entering a coating film in the long-time special environment (such as a high-salt and high-humidity environment) storage and transportation process, so that corrosion on the surface of the steel coil is slowed down or even eliminated. The packaging method is simple, low in energy consumption and low in cost, has good practicability and has application potential in the field of packaging of the 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] Cold-rolled steel sheets will be used directly or as basic coatings after being prepared into coils. The surface quality and specifications of the sheets 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 in the steel coil storage and transportation process to overcome the rust prevention problem of the quality of the plate surface. [0003] At present, waterproof packaging (waterproof paper packaging, heat shrinkable film packaging), gas phase antirust packaging (gas phase antirust paper / film packaging), dry air packaging (aluminum-plastic composite film + desiccant packaging) and other packaging technologies are mainly used at home and abroad. Packaging...
