Rohlings

Rohlings is a term used in metallurgy to describe a preliminary shape of metal that is later processed into a finished product. These shapes are typically cast in a mold or formed by rolling and are characterized by their large size and rough surface. Common forms of rohling include ingots, billets, and slabs. Ingots are the largest and most basic form, often cast directly from molten metal. Billets are usually square or rectangular and are typically produced by cutting or breaking down larger ingots. Slabs are wider and flatter than billets, and are commonly used for producing flat products like plates and sheets.

The primary purpose of creating rohling is to provide a manageable and standardized intermediate form for further manufacturing processes. This allows for efficient handling, transportation, and subsequent shaping of the metal. Rolling mills are often used to further reduce the cross-section of the rohling and to impart a more precise shape and desired mechanical properties. For example, steel rohling in the form of billets can be heated and then passed through a series of rollers to produce steel bars or rods. Similarly, aluminum slabs are often rolled into sheets for use in aircraft construction or beverage cans. The specific composition of the metal and the intended final product dictate the size, shape, and quality requirements of the rohling.
