Knowledge of hot rolling slitting line

Source:     Time:2020-04-24 Hits:

Last time, we have known a lot about cold rolled steel. This time, we have to talk about the hot rolled steel and the hot rolling slitting line.

Like cold rolled steel, hot rolled steel is flat. However, when comparing cold rolled steel to hot rolled steel, the difference begins with the temperature at which the metal is processed. The hot rolled steel goes through the rollers at a much higher temperature, it will change shape and size during the cooling process, making it less ideal for project requiring uniform thickness. Hot rolled steel also has a rougher finish and is not as strong as cold rolled steel.

 

There are also some benefits when using hot rolled steel instead of cold rolled steel. Hot rolled steel is more malleable, so it is easier to work with both during and after the rolling process. This malleability also means that hot rolled steel is lower cost, due to fewer steps in the hot rolling process. For example, the metal doesn’t need to be cooled before being sent through the rollers, and is able to be significantly reduced in thickness with only one pass (compared to cold rolling, which requires multiple passes). Hot rolled steel is best used for products like rail tracks and I-beams, which are produced in high quantities and do not require a clean finish.
