1.How much is the price of carbon steel coil?

    Carbon steel coil is made of slab, heated by heating furnace and rolled by roughing mill group and finishing mill group. The hot strip from the last finishing mill is cooled and rolled into coils by the crimping machine. According to the different needs of users, through different finishing line processing to become steel plate, flat coil and slitting steel products. Carbon steel coils from Chinese factories are sold at the best and most favorable prices. At present, the factory price of carbon steel coil is 549.15USD/ton-706.05USD/ton.

2.What is the specification of carbon steel coil？

3.How to pack carbon steel coil?

    1. Selection of packaging method from factory

    (1) When the packaging rhythm is less than 6~8 rolls /h, manual packaging can be used, conveying and auxiliary equipment can be configured according to the need to reduce labor intensity 

    (2) When it is 8~18 rolls /h, it is suitable to use semi-automatic packaging machine, which can automatically complete the wrapping paper and the outer iron sheet. The semi-automatic baling machine can greatly reduce the labor intensity of workers and improve the efficiency and packaging quality. 

    (3) When the packaging rhythm is 15~24 rolls /h, it is suitable to use automatic packaging machine

    2.Steel coil packaging process

    Coil packaging can protect coil from damage in storage and transportation, but also increase the cost of the product. Therefore, what kind of packaging technology can reduce the cost, is the market economy under the condition of each factory should pay attention to and study the problem. Due to the introduction of cold rolling technology and equipment in China, the packaging of products is no exception. Over the years, Chinese enterprises basically follow the original packaging technology learned from abroad, without innovation. In recent years, packaging materials and methods abroad have been greatly improved.

    3.kind of package

    There are two kinds of packaging processes:

    The first is simple packaging: the steel coil is fixed by binding 1-3 steel belts on the outer circle after the completion of coiling. The process is suitable for hot rolled coil, cold hard coil and short distance transportation and transportation conditions of steel coil are better.

    The second is fine packaging: according to the requirements of the packaging process, different packaging materials are wrapped on the outer surface of the steel coil and bundled to finalize the design. The process is suitable for cold rolled plates, especially silicon steel plates.

    4. Packaging materials

    Packaging materials include anti-rust paper, plastic bag, inner iron sheet, outer iron sheet, inner paper Angle guard, outer paper Angle guard, end protection plate, inner iron Angle guard, outer iron Angle guard, binding belt pad, holding belt, etc., as shown in Figure 1. The functions of various packaging materials are as follows:

    (1) antirust paper: with gas phase and contact double antirust performance, more than three layers of composite structure, close to the outer surface of the steel coil, the steel plate packaging space have anti-rust effect: provide steel plate sealing packaging waterproof and moisture-proof barrier function; Achieve the physical properties of steel plate packaging materials.

    (2) Plastic bags: wrapped in rust-proof paper, used for waterproof.

    (3) Inside and outside iron sheet: protective steel coil, rust-proof paper and plastic bag.

    (4) Thick plastic plate: reduce the impact of lifting on steel coil.

    (5) Inner and outer iron Angle protection: protect the edge of the most vulnerable steel coil. (6) Inner and outer paper Angle protection: protect the rust-proof paper and plastic bags, avoid being scratched by the edge of the steel coil.

    (7) carrying pad: mainly used for pneumatic locking baling machine, fixed joint, prevent local stress is too large.

    (8) Circumferential binding belt: usually 3 lanes, the next two lanes are used to fix the outer iron Angle guard, and the middle one is used to fix the rolling eye binding belt. (9) Rolling eye binding belt: 4 inverse or 6 lanes, the rolling eye binding belt really plays the role of fixing the steel coil.
