Hot Rolled Steel Products Types and Applications
Hot rolled steel is steel that has been rolled at high temperatures above 1700°F, which is above the recrystallization temperature of most steels. This makes steel easier to mold, and also results in an easier product to process. Processing hot-rolled steel, manufacturers firstly start with a large, rectangular piece of metal which called a billet. The billets are heated and then sent to preprocessing where they are flattened into large rolls. From there, it is kept at high temperatures and passed through a series of rollers to reach its final size. White-hot steel wire is pushed through the drum at high speed. For sheet metal, rolled steel is rolled into coils and cooled.The material is segmented and packaged for other shapes, such as rods or sheets. Steel shrinks slightly when cooled. After processing,hot rolled steel is cooled, so there is less control over its final form, making it less suitable for precision applications. Hot...
