Rods or wires are produced from steel billets by undergoing a process called hot rolling. This process involves passing the steel billets through a series of rollers at high temperatures. The initial step is to heat the billets to a temperature above their recrystallization point, which is typically around 1200-1300 degrees Celsius. This temperature is important as it ensures the steel becomes soft and easily malleable, thus facilitating the shaping process.
Once the billets have been heated, they are then fed through a series of rollers that gradually decrease their thickness and give them the desired rod or wire shape. The rollers exert pressure on the billets, causing them to elongate and reduce in thickness. The number and arrangement of the rollers may vary depending on the specific requirements of the rod or wire being manufactured.
Throughout the hot rolling process, the steel undergoes plastic deformation due to the combination of applied pressure and high temperatures. This plastic deformation enables the steel to change its shape without breaking or cracking. The continuous rolling and reduction in thickness gradually transform the billets into rods or wires.
After achieving the desired size and shape, the steel is cooled, typically using air cooling. This cooling process enables the steel to maintain its new shape and hardness. The cooled rods or wires can then undergo further processing, such as additional heat treatments or surface treatments, to enhance their properties and meet specific requirements.
In conclusion, the hot rolling process is indispensable in shaping steel billets into rods or wires. It allows for precise control over dimensions and properties, while ensuring the final product meets the desired specifications.
