1. Material characteristics of round steel
Round steel is a hollow cylindrical metal material that is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries.
Round steel is mainly made of carbon steel, alloy steel and tool steel. Among them, carbon steel round steel refers to steel with a carbon content within the range of 0.20% to 0.55%. Carbon steel round bar has good weldability, plasticity and processability, and is an economical and practical structural material. Alloy steel round steel refers to steel with a certain amount of alloying elements added (chromium, manganese, cobalt, boron, molybdenum, vanadium, etc.) to obtain higher strength, hardness, corrosion resistance, wear resistance and other properties. Tool steel round steel is a high-speed tool steel material with the advantages of high hardness, high red hardness and wear resistance. Therefore, the material characteristics and application range of round steel are very different.
2. Manufacturing process of round steel
The manufacturing processes of round steel are very diverse, including hot rolling, cold drawing manufacturing and cold drawing manufacturing. Among them, the hot rolling production process refers to heating the steel material to a certain temperature, plastically deforming it through rolling machinery and equipment, and pressing it into steel materials of different specifications and shapes. The cold drawing production process uses steel wire materials for cold drawing, which can obtain a higher surface finish and be used to make precision parts. The cold drawing production process is to draw steel in a cold storage to obtain higher density, hardness, strength and other properties.
3. Use of round steel
The wide application of round steel lies in its material characteristics and production technology, which can meet the needs of different industries. In construction projects, round steel is mainly used to build steel structure houses, large factories, bridges, oil drilling platforms and oil extraction equipment. In the machinery manufacturing industry, round steel is mainly used for processing into gears, bearings, connecting rods, pins, shafts and other parts. In the automobile manufacturing industry, round steel is mainly used to make automobile parts, frames, suspension systems, guide mechanisms, etc. It is also widely used in energy, transportation and other industries.
Conclusion:
Round steel is a metal material with a wide range of applications, with different material characteristics and production processes. Through the introduction of this article, readers can have a better overall understanding of round steel.
Zhengde Steel Round bar refers to a solid strip of steel with a circular cross section. Its specifications are expressed in millimeters of diameter, such as "50" means a round steel with a diameter of 50 mm. Steel Round bar is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight strips, which are often used as bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts or seamless steel pipe billets.
The difference between steel Round bar and other steel bars: The shape is different. The shape of round bar is smooth and round, without grain and ribs. Other steel bars have grooves or ribs on the surface, which will cause the bond between round bar and concrete. Small, while other steel bars have a strong bond with concrete.
