How is scrap metal can processed after recycling?

The processing and treatment of recycled iron cans is a complex and important process that not only helps in resource reuse but also reduces environmental pollution. The following is a general processing flow after the recycling of iron cans:

1. Collection and Classification

The recycled iron cans first need to be classified. Classification based on the material, degree of rust, contamination, etc., helps improve the efficiency of subsequent processing.

2. Crushing and Magnetic Separation

After being processed by a crusher, the iron parts can be separated from other non-iron parts using magnetic separation equipment. This step helps improve the purity and recovery rate of the iron metal.

3. Cleaning and Decontamination

The crushed and magnetically separated iron materials need to be cleaned to remove surface oil stains, impurities, etc. This step can be completed through water washing, mechanical cleaning, or chemical cleaning methods.

4. Smelting and Refining

The cleaned scrap iron can be sent to a smelting furnace for melting. During this process, impurities can be further removed to obtain high-purity molten iron.

5. Refining and Shaping

The refining process aims to further improve the quality of the iron by removing harmful impurities. The refined molten iron can be cast into different products as needed, such as steel billets, wire rods, steel plates, etc.

6. Testing and Quality Control

在加工处理过程中，需要对各个环节进行严格的质
