Description
Technical field
The present invention relates to a kind of two slow type packing method of the shield of the three of cold-rolled steel coils, belong to cold-rolled steel coils packing method field.
Background technology
With high-endization of customer group, the variation of transportation range and means of transportation, the packaging quality of cold-rolled products will
Ask more strict, steel roll package is increasingly paid attention to by major steel enterprise packaging field.Each producer all seek one kind can
Meet the packed steel coil of different requirements.
The main purpose of cold-rolled steel coils packaging is in order to which good protection product is in production, transport, storage and terminal distribution
During do not encroached on.Packaging can be summarized as antirust waterproof with regard to its effect, protects and tie up anti-scattered three aspects, generate difference
The cold rolling packaging coil of strip of species is to adapt to the demand in market.
Because of situations such as region, haul distance, means of transportation, transfer handling influence, in terms of steel roll package protection, coil of strip
Periphery is protected and corner protection is always the emphasis of packaging industry research, and most of quality objections are all thus to occur.
In order to ensure the final product quality of cold-rolled steel coils, coil of strip will not be damaged because of long-distance transport, and then influenceed in next step
Production and processing to the manner of packing of existing cold-rolled steel coils, it is necessary to be further improved.
The content of the invention
It is an object of the invention to provide a kind of two slow type packing method of the shield of the three of cold-rolled steel coils, the packaging has structure section
Learn, production, packaging, storage and terminal distribution during it is not easily damaged the characteristics of, so as to solve what is be previously mentioned in technical background
Problem.
Three shields, the two slow type packing method of a kind of cold-rolled steel coils, it is characterised in that its packing method step is as follows：
1) polyethylene inner protective corner and outer protective polyethylene angle are packed in coil of strip internal-and external diameter edge corner, polyethylene inner protective corner and poly-
The outer corner protector of ethene is by pure polyethylene particle, color masterbatch, foaming agent proportioning mixing, is merged compound through high temperature by corner protector production line
For melt, melt is molded by particular mold, then carries out cooling and shaping by cooling system, then carry out corner protector tooth form punching and
Into, its specification is 2.0~3.5mm × 60 × 90 × 1500~6000 (mm)；
2) inner core volatile rust preventive paper is filled on coil of strip inner core perimeter surface is close to, the width of inner core volatile rust preventive paper is wider than coil of strip
Wide 60mm is spent, the part both sides that width goes out symmetrically are turned up and are affixed on the side end face of polyethylene inner protective corner, then prevent periphery gas phase
Rust paper is close to be mounted in coil of strip outer surface and end face, and coil of strip inner core is ploughed under after cascade fold, is overlapped with inner core volatile rust preventive paper, uses adhesive tape
Totally-enclosed bonding；
3) coil of strip circumferential seal is first bonded by the polyethylene film for being 0.1mm with thickness specification, then by radial direction one
The polyethylene film at end is Nian Jie with the polyethylene film of the radial direction other end through coil of strip inner core, the lap of splice 100mm, Ran Houyong
Adhesive tape adhering and sealing；
