  Technology for heating processing
  • General steel heat treatment includes the following techniques:
    Quenching

    Steel is heated to a temperature higher than its transformation point to form austenite; then the steel is quickly cooled to form martensite. This process increases the hardness and strength of the steel without changing its shape, but the steel becomes more brittle.

    
    
    

    Tempering

    Heating the steel again after quenching adds elasticity and toughness, transforming the steel to a structure with high resistance to wear. However, the hardness is slightly reduced when compared with the state after quenching..
    Annealing

    This process is used to improve the structure and soften the steel since semi-hard steel, hard steel and alloy steel are difficult to cut due to their hardness.

    
    • 
      • Normalizing
        This process is used to make the structure finer, uniformize carbides and remove residual stresses, thus making the steel easier to cut. Since hardenability also improves, normalizing is sometimes used as a pre-process before quenching.

     2.Inspection Machining检测机器

     How do you test the composition of a metal?怎样测试金属的成分?

    The two most common methods used to determine the chemical composition of an alloy (or any metal) are

    X-ray fluorescence spectroscopy (XRF) and optical emission spectroscopy       (OES). XRF is non-destructive,

    however, OES is more sensitive than XRF to lighter elements.

     Packaging Services

Packaging

In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)
GB／T191packaging-pictorial marking for handling of goods
GB／T4857 (all parts) basic test for transport packages
GB／T4879 rustproof packaging
GB／T5048 damp-proof packing
GB／T7350water-proof packing
GB／T8166 Package cushioning design
GB/T4892-1996 Hard straight square transport packaging size series
GB/T13201-91 Cylinder transport package size series
GB/T16471-1996Design and make the size limit of transport package

Packing mark description: graphics should have a realistic sense; If there are standards for graphic symbols, they shall be used in accordance with relevant standards. The selection of primary color should fully consider the characteristics of the contents, packaging intention; The shape of the main text should consider readability; The descriptive text should be clear and neat, and printed as far as possible; The type and font should meet the requirements of the specification and keep the writing clear and variable for a long time

 LOGISTIC

The modes of foreign trade logistics mainly include the following: ‌

1.Sea transport ‌ : Sea transport is the most important mode of transport in international trade, suitable for bulk goods and long distance transport. Its advantage is that the transport volume is large, the cost is low, but the speed is slow and is greatly affected by the weather and sea conditions. Sea freight is usually used for goods that are not time-intensive, such as raw materials and large industrial manufactured goods. ‌ 1

2 ‌.Railway transportation‌ : Railway transport is noted for its large volume, high speed, little influence on climate, and safety and punctuality. Although infrastructure construction and high maintenance costs are challenges, they are still an important option in cross-border bulk cargo transportation. ‌ Air ‌ : Air transport has the advantage of extremely fast speed and high safety in the transportation of urgent and high-value goods, but the transportation cost is high, and it is usually used for scenes with extremely high time requirements or high value of goods, such as electronic products, precision instruments and fresh food. ‌ road transport ‌ : road transport is flexible and suitable for the transport of goods in short distances or between neighboring countries. Costs rise significantly as transport distances increase, making it more suitable for short distances or for transport needs that require a quick response. ‌ express ‌ : suitable for small goods or urgent goods, fast and convenient but high cost. Courier companies such as DHL, UPS, FedEx, etc., provide door-to-door service. ‌

3 ‌ Airlines ‌ : The whole process of transport by large trucks, suitable for certain time requirements and the volume or size of the cargo is not suitable for sea or rail transport scenarios. ‌

4. pipeline transportation ‌ : mainly used for the transportation of oil, natural gas and chemicals, with the characteristics of large volume, strong continuity, safety and reliability. ‌

5. postal transportation ‌ : The delivery of goods through the postal system, suitable for lightweight and small goods, such as precision instruments, machinery parts, medicines and so on. ‌

Factors to consider when choosing the right logistics method include ‌ : ‌

1. safety ‌ : to ensure the safety of the goods during transportation. ‌

2. time of shipment ‌ : meet the requirements of arrival time of the goods. ‌

Transportation expenses ‌ : Control logistics costs to optimize business operations. ‌
