Cold Roll Forming VS Hot Rolling Forming
Why should we choose different rolling processes? Different applications correspond to different processes. It is important to choose products with appropriate processes.We have made a distinction here between the two processes. 1.Different properties Cold roll formed section steel: it refers to the section steel of various cross section shapes and sizes made of hot rolled or cold rolled strip steel by roll formed. Hot rolled section steel: It refers to the steel with various geometric section shapes rolled from heated steel billets. 2. Different processes Cold roll formed steel: cold roll formed steel is the main material for making light steel structure, which is made of steel plate or steel strip by cold forming. Its wall thickness can not only be made very thin, but also greatly simplifies the production process and improves the production efficiency. It can produce various sections and cold-formed sections of different materials with uniform wall thickness and complex section shape that are difficult to produce by the general hot rolling method. Hot rolled section steel: most of the hot rolled section steel of low alloy steel is hot-rolled deformed bar and section steel rolled with 16Mn, and the special-shaped section steel is less used.
