Corme

Corme is a term used to refer to a type of finishing mill stand designed for hot rolling in the steel industry. It is a machine used to roll metal in a specific way to produce a desired shape or thickness. The corme is a high-speed finish rolling mill stand that is capable of achieving very precise control over the thickness and surface quality of the rolled metal.

The term corme is thought to be derived from the French word "côrme," which means hump or edge. This refers to the corme's unique ability to produce a smooth and flat edge on the rolled metal, often referred to as a "skin" or "flat skin." This is achieved by using a series of rolls, each designed to work together to remove excess material and flatten the metal.

Corme rolling is typically used for high-speed finishing of large-diameter blooms or slabs in the steel industry. The process involves rolling the hot metal through the corme stand at speeds of up to 180 meters per minute, resulting in a final product with precision-controlled thickness and surface finish. This process is essential for producing high-strength, high-quality steel products used in various industries, including construction, automotive, and heavy equipment.

Corme stands have gained significant popularity in recent years due to their ability to improve the efficiency and accuracy of steel production. However, they are relatively expensive to purchase and maintain and typically represent a large capital investment for the steel industry.
