The production process of carbon steel round bars typically involves several steps:
1,Melting: The primary raw materials for carbon steel are iron ore and scrap steel. These are melted in a blast furnace or electric arc furnace to remove impurities and produce molten steel. The carbon content is adjusted based on the required steel grade.
2,Casting and Forming: The molten steel is then poured into molds to form steel billets. These billets are usually rectangular or circular semi-finished products. Continuous casting or ingot casting methods are used to solidify the molten steel into billets.
3,Hot Rolling: The steel billets are heated to high temperatures and passed through a rolling mill. The hot rolling process reduces the billet into a round bar by passing it through multiple rollers, gradually achieving the desired diameter and length.
4,Cooling and Cutting: After rolling, the round bars are cooled to room temperature, then cut to the required length.
5,Inspection and Packaging: Finally, the round bars undergo quality control to ensure they meet size, surface finish, and mechanical properties standards before being packaged for shipment
Carbon steel round bars are primarily made from low to medium-carbon steel, typically containing 0.05% to 0.25% carbon content. Common standards for carbon steel round bars include ASTM A36, ASTM A105, and DIN 1013. These standards specify the material's mechanical properties, such as tensile strength, yield strength, and elongation, as well as chemical composition.
Carbon steel round bars are widely used in construction, machinery, automotive, and manufacturing industries. They are used for structural components like beams, shafts, bolts, and gears. Due to their high strength, durability, and ease of machining, they are ideal for applications requiring toughness and resistance to wear and tear.
