PRODUCT PRODUCTION PROCESS

1. Preparation of raw materials
1. Material selection: Choose high-quality steel with good quality, no oxide scale, no cracks or cracks, and few impurities as raw materials.
2. Cutting: Cut the raw materials into appropriate lengths and diameters, ensuring that the cutting surface is bright and crack-free.
2. Refining
1. Impurity removal: Use magnetic separator or manual sorting to remove impurities in raw materials.
2. Preheating: heating the raw materials to a certain temperature in the furnace for subsequent operations.
3. Refining: Put the preheated raw materials into a refining furnace for high-temperature treatment to remove harmful substances such as carbon, sulfur, and phosphorus in the raw materials, and adjust the carbon content.
3. Processing and forming
1. Preforming: Processing the refined raw materials into bars of a certain shape.
2. Heat treatment: Heat the preformed rod to a certain temperature and keep it for a period of time to adjust the mechanical properties of the rod.
3. Cooling: Place the heated rod in the air to cool naturally.
4. Finishing: The steel round bar is further subjected to fine processing such as wire cutting and polishing to achieve higher precision and surface quality.
