- Q: What is the difference between a hot-rolled and a peeled steel round bar?
- A hot-rolled steel round bar is produced by heating a billet or ingot until it reaches a temperature where the material can be easily shaped or formed. Once heated, the steel is rolled through a series of rollers to achieve the desired shape and size. The process of hot rolling creates a bar with a rough surface texture and a slightly rounded edge. On the other hand, a peeled steel round bar undergoes a different manufacturing process. It is first hot-rolled to achieve the desired shape and size, similar to the hot-rolled bar. However, after the initial hot rolling, the peeled bar is subjected to a mechanical peeling process. This involves removing the outer layer of the bar to achieve a smooth, shiny surface finish. The peeling process also helps to improve the dimensional accuracy and surface quality of the bar. In summary, the main difference between a hot-rolled and a peeled steel round bar lies in the surface finish and dimensional accuracy. While a hot-rolled bar has a rough surface texture and a slightly rounded edge, a peeled bar has a smooth, shiny surface finish with improved dimensional accuracy. The peeling process enhances the overall quality and appearance of the steel round bar, making it more suitable for applications where aesthetics or precision is important.
