Question

Accepted Answer

Hot rolling is a metalworking process where metal is heated above its recrystallization temperature and then passed through rollers to form sheets or bars.

Hot rolling is used to produce sheets, plates, and bars of various thicknesses and shapes.
The metal is heated above its recrystallization temperature to make it easier to shape.
The metal is then passed through rollers to reduce its thickness and shape it into the desired form.
Crystal structure refers to the arrangement of atoms in a material.
Cold work is the process of shaping metal at room temperature, which can make it stronger but also more brittle.
