Raw material processing: First, select high-quality stainless steel blanks as raw materials and conduct quality inspections to ensure that the raw materials meet the requirements. The raw material is then heated to remove impurities and bubbles inside it.
The production process of stainless steel rods mainly includes raw material processing, smelting, continuous casting, rolling and surface treatment.
1. Raw material processing: First, select high-quality stainless steel blanks as raw materials and conduct quality inspections to ensure that the raw materials meet the requirements. The raw material is then heated to remove impurities and bubbles inside it.
2. Smelting: Put the heated raw materials into the smelting furnace, and add appropriate amounts of alloy elements and other additives. Through high-temperature heating and chemical reactions, the raw materials are melted into liquid metal.
3. Continuous casting: Pour the molten metal into the continuous casting machine, and cool the liquid metal into a continuous billet through continuous casting. The continuous caster adjusts the cooling rate as needed to control the crystal structure and size of the billet.
4. Rolling: Send the cooled billet into the rolling mill for rolling. The rolling mill gradually stretches, flattens and gradually reduces the cross-sectional size of the billet so that it becomes a stainless steel rod of the required diameter. During the rolling process, parameters such as the temperature, rolling speed and rolling force of the rolling mill need to be controlled to ensure the dimensional accuracy and surface quality of the product.
5. Surface treatment: There may be some oxides and scale on the surface of rolled stainless steel rods, which require surface treatment processes such as pickling or shot blasting to remove these impurities. At the same time, stainless steel rods can also be polished, polished and other surface treatments to improve their appearance quality.
The above is the main production process of stainless steel rods. During the entire process, the process parameters of each link need to be strictly controlled to ensure product quality and performance. At the same time, the waste materials and wastewater generated also need to be treated to protect the environment.

Cold rolled steel processing methods
Cold rolled steel is steel produced by cold rolling. Cold rolling is to further thin the No. 1 steel plate to a target thickness under room temperature conditions. Compared with hot-rolled steel plates, cold-rolled steel plates have a more precise thickness, smooth and beautiful surface, and have various superior mechanical properties, especially in terms of processing performance.

Corrugated board, also called profiled board, is made of color-coated steel sheets, galvanized sheets and other metal sheets that are rolled and cold-bent into various corrugated profiled boards. It is suitable for industrial and civil buildings, warehouses, special buildings, and large-span buildings. Roofs, walls and interior and exterior wall decoration of steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fireproof, rainproof, long life, maintenance-free, etc., and has been widely promoted and used.
