Hot Rolled Plates for strong construction

Hot rolled plates are the form of metal which is rolled in between two or more pairs of rollers to reduce the thickness of metal and make it uniform. Rolling is classified according to the temperature used in its making, which is of two types. Hot Rolling- when the temperature is more than the recrystallization temperature, it is hot rolling and when the temperature is below recrystallization temperature, it is cold rolling. In industry, Hot Rolling is used widely for its better results.

Hot RolledPlates  can use different processes for their making. Some of the basic process include roll forming, controlled rolling, ring rolling, profile rolling and roll bending. Rolling of iron and steel sheets are traced back to 16^th century where it was rolled by using hammer and it used to be a time taking process. Modern rolling was introduced in the late 17^th century where new designed mills were able to produce 15 times more output per day as compared to the hammer. 

In rolling, flatness, profile and shape are the most important characteristics that need to be considered. Profile is made of measurement of crown and wedge of metal. Crown is present in the thickness of the center as compared to the average thickness of edges.

Flatness refers to the thickness of metal sheet all around. Basically, a uniform gap between rolls is difficult to maintain as rolls deflect from the heavy load required to deform the work piece, which make work piece non-uniformed on the edges and on middle. This can be overcome by using crowned roller or parabolic crown but it can control only one set of condition between temperature, material or amount of deformation. Hot rolled metals are widely used in various industries that include aerospace, marine and nuclear construction along with several others for a strong and reliable platform.
