Abstract

The invention discloses an external packing method of a silver bright bar, which comprises the following steps: wrapping the bundled silver bright bars by using a plastic film bag, and then wrapping a soft wrapping layer; and placing a plurality of hard support bars on the outer surface of the soft package layer along the circumferential direction, and finally bundling and fixing the hard support bars by using a packaging tape. The invention can effectively ensure that the oil coating is kept and does not leak through the plastic film bag, and an effective anti-abrasion layer is formed on the surface of the round steel and the outside through the soft cladding and the hard supporting strips to protect the surface quality.

Description

External packing method of bright silver bar

Technical Field

The invention relates to a packaging method in the field of metallurgy, in particular to an external packaging method of a bright silver bar.

Background

According to the requirements of users, the surfaces of the hot rolled bars need to be polished and silvery, and the surfaces are smooth after being processed, but the surfaces are easy to rust and scratch in the subsequent transferring process because the surfaces are wrapped by iron wires by using a common packaging method.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides an external packing method of a silvery bright bar, which effectively retains oil, prevents leakage and prevents collision and scratch caused by mutual extrusion in subsequent hoisting, transporting and transporting processes.

The technical scheme is as follows: the outer packing method of the silver bright bar comprises the following steps:

(1) wrapping the bundled silver bright bars by using a plastic film bag, and then wrapping a soft wrapping layer;

(2) and placing a plurality of hard support bars on the outer surface of the soft package layer along the circumferential direction, and finally bundling and fixing the hard support bars by using a packaging tape.

Preferably, the soft covering layer is a woven gunny bag. The wrapping woven gunny bag effectively isolates external hard objects (bamboo chips, during hoisting, stacking and the like) from being in direct contact with the plastic film, so that the film is damaged.

Preferably, each hard supporting strip is arranged along the length direction of the silver bright bar material.

Preferably, the plurality of hard support strips are uniformly distributed around the circumference of the soft cladding.

The hard supporting strips are made of wood strips or bamboo chips. Can provide enough packaging strength, reduce weight as much as possible, reduce cost and prevent the surface of the round steel from being damaged by extrusion of convex objects and the like.

The size of the supporting bar is 50mm multiplied by 5mm multiplied by the fixed length of the round steel.

Has the advantages that:

the plastic film bag can effectively ensure that the oiled steel can be retained without leakage, and an effective anti-collision layer is formed on the surface of the round steel and the outside through the soft cladding and the hard supporting strips to protect the surface quality.

Detailed Description

The invention will be further elucidated with reference to the following specific examples.

An outer packing method of a silver bright rod material comprises the following steps:

1. after processing and oiling the silvery bright bars, wrapping the bunched silvery bright bars (the thickness is 0.8mm and the width is 500mm, and the general tonnage is not more than 2.5 tons and is determined according to the requirements and specifications of customers) from one end to the other end by using a pre-fabricated plastic film bag, so that oiling leakage is prevented, and meanwhile, water vapor in the air is prevented from entering;

2. wrapping the silver bright material with a woven gunny bag; the wrapping woven gunny bag effectively isolates external hard objects (bamboo chips, during hoisting, stacking and the like) from being in direct contact with the plastic film, so that the film is damaged;

3. uniformly placing 8 bamboo chips or wood strips with the length of 50mm multiplied by 5mm multiplied by the fixed length of the round steel outside the woven gunny bag along the circumferential direction so as to prevent the surface of the round steel from being damaged by extrusion of convex objects and the like;

4. and finally, uniformly distributing and bundling 5-7 packaging tapes 0.9mm multiplied by 32mm (universal size) along the length direction by using the packaging tapes for fixing and bundling woven bags, bamboo chips and bright round steel.

The silver bright bars are packaged for 120 pieces according to the method, the total weight is about 300 tons, and the phenomena of oil leakage and surface damage do not occur after transportation.

Claims
