Rolling Mill or a Partially automated or a Manual Rolling Mill. Rolling is the most widely used metal forming process. It is employed to convert metal ingots to products like blooms, billets, sheets, plates, strips etc. The main objective of rolling is to decrease the thickness of the metal and give it a desired profile.
Main Types of Rolling Mills. The different types of metal and the specifications of the final product will help determine which type of rolling mill your product will be produced with. Here are a few of the main types of rolling mills: Continuous rolling mill. Sheet metal passes through several rolling stands, each pressing the metal thinner.
