Steel Plate Rolling
Hot Rolling Steel
Hot rolling involves rolling steel at temperatures beyond its recrystallization process. That recrystallization process occurs when the steel reaches temperatures between 400-degrees and 700-degrees Fahrenheit. It’s at these temperatures that the steel’s chemical and mechanical properties start to change as the steel’s grain structure is realigned in the direction of the rolling process.
Hot rolling steel is done at temperatures above 1,700 degrees Fahrenheit. During this process, the steel itself becomes “softer”, which means it is much easier to elongate and form into a thinner substrate as it is compressed through the rollers. The steel is then allowed to cool at room temperature where its final size is drastically changed. Ultimately, because the steel’s cooling process is not controlled, the result is a steel surface and shape that is not perfectly uniform.
Benefits of Hot Rolling Steel
Hot rolling steel makes the steel easier to work with while also improving its ductility. That steel can then be cast and formed into multiple different shapes, sizes, and configurations. The final product is less expensive and has lower porosity levels compared to cold rolling. The lower porosity is because the steel is allowed to cool down gradually at room temperature without quenching. Hot-rolled steel is a good solution for applications where the dimensional tolerances of the steel aren’t critical.
- Less expensive than cold-rolled steel.
- Fewer problems with porosity.
- The steel becomes malleable and easy to work with.
- Ideal for situations where dimensional tolerances aren’t critical.
Cold Rolling Steel
Benefits of Cold Rolling Steel
Putting steel through this additional step increases the steel’s strength and hardness while also allowing the steel to withstand higher stress levels. Unlike hot-rolled steel where the material’s tolerances aren’t ideal, cold-rolled steel has tolerances that are more uniform, which makes the steel ideal for high-precision machining. This is because the cooling down process is controlled, which leads to steel with tighter dimensional tolerances and a smoother surface finish.
- Increased strength.
- Increased hardness.
- Capable of handling higher stress levels (loads).
- Smoother surface finish and tighter dimensional tolerances.
- Ideal for high-precision machining.
