Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed
into more functional shapes and sizes. While they have already been put in the furnace, they still require
a series of shaping and molding procedures such as hot and cold working, milling and cutting before they
are sold in hardware stores, or used for different applications. The unformed billets, however, can be used
in striking currency such as coins and as reserves, similar to gold bars.

- Q: How are steel billets used in the production of reinforcement bars?
- Rebar production relies heavily on steel billets, which are integral components. These billets, resembling rectangular or square semi-finished steel products, act as the initial stage in the manufacturing process. To create rebar, the steel billets are first heated to a temperature surpassing their recrystallization point in a furnace. This procedure, known as hot rolling, involves passing the heated billets through a series of rollers. These rollers gradually decrease the billets' cross-sectional area while elongating the material. Consequently, the billets transform into long, slender bars possessing the desired mechanical properties and dimensions. Throughout the hot rolling process, the steel billets experience significant plastic deformation. This deformation leads to the realignment of grains within the material, resulting in a more uniform and compact structure. This refined microstructure enhances the strength and durability of the rebar, thereby making it ideal for construction projects necessitating high tensile strength, such as reinforced concrete structures. The size and shape of the steel billets employed in rebar production vary according to specific end-product requirements. It is crucial to note that the quality of the billets plays a vital role in determining the rebar's overall quality. Therefore, manufacturers must meticulously select and inspect the billets to ensure they meet the required specifications and standards. In conclusion, steel billets are indispensable in rebar production as they undergo transformation through the hot rolling process, resulting in the desired shape and dimensions. The resulting rebar exhibits enhanced strength and durability, rendering it suitable for reinforcing concrete structures and ensuring their structural integrity.
