How did steel become a mind map?

Of course, the production of steel was not a simple process. It required many stages and steps. The following are the main contents and processes of steel production: [1. Collection of raw materials: To produce steel, you need to collect raw materials such as ores, coal, and sand.] 2. Melting and refining: The raw materials are melted and refined to obtain more steel products. During this process, one needed to control the heat, the proportion of the blocks and the alloy, and so on. 3. Crystallization: When the original material is melted, it will produce multiple crystals. Some of the crystals will become the main crystal such as the crystal and steel crystal. 4. Cold and processing: Cold and processing the steel product on the basis of the crystal to remove the pressure and color on the crystal. 5. Magnetic beast transformation: Steel products will be magnetic beast transformation in the cold and processing process. This process can remove the magnetic quality of steel products. 6. Processing and production: During the process of magnetic beastification, the processed steel products will be produced into different types and size such as steel records, steel sheets, steel wires, etc. Inspection and quality control: In the production process, multiple inspections and quality control are needed to ensure that the product quality meets the standards. In general, steel production was a complex and compact process that required many stages and steps to produce high-quality steel products.
