- Q:What is the difference between a rough turned and a hot rolled steel round bar?
- A rough turned steel round bar and a hot rolled steel round bar differ in their manufacturing processes and resulting properties. A rough turned steel round bar is produced by first heating a steel billet or ingot to a high temperature and then subjecting it to rough machining processes. The rough machining involves removing excess material from the surface of the bar to achieve a desired size and shape. This process results in a slightly smoother surface compared to the hot rolled bar, but it may still have some minor imperfections. Rough turned bars are often used in applications where a smoother surface finish is required, such as in machining operations. On the other hand, a hot rolled steel round bar is manufactured by heating a steel billet or ingot to extremely high temperatures and then passing it through a series of rolling mills. The hot rolling process involves reducing the thickness and increasing the length of the steel bar by compressing it between a set of rotating rolls. As a result, hot rolled bars have a rough, scaled surface with variations in diameter along their length. This textured surface provides excellent adherence for paint, coatings, or further processing. Hot rolled bars are commonly used in construction, manufacturing, and structural applications where mechanical properties such as strength and durability are important. In summary, the main difference between a rough turned and a hot rolled steel round bar lies in their manufacturing processes and surface finish. Rough turned bars undergo rough machining to achieve a smoother surface, while hot rolled bars are formed through high-temperature rolling, resulting in a rough, scaled surface. The choice between these two types of bars depends on the specific application and the desired properties, such as surface finish, strength, and adherence.
