Steel plates with rolling

Steel plates with rolling refer to the process of manufacturing steel plates by passing heated metal through a series of rolling mills. This process involves applying pressure and reducing the thickness of the metal to achieve the desired plate dimensions.

Here are the general steps involved in producing steel plates with rolling:

Steel Melting and Casting: The production process begins with melting steel in a furnace, typically using electric arc furnaces or basic oxygen furnaces. The molten steel is then cast into large rectangular molds called slabs.

Heating and Reheating: The slabs are reheated in a furnace to an optimal temperature for rolling. This ensures the steel's malleability and facilitates the shaping process.

Roughing Mill: The heated slab enters a roughing mill where it undergoes several rolling passes to reduce its thickness and increase its length. The slab is squeezed between two rotating rolls to gradually shape it into a thinner and longer piece known as a transfer bar.

Finishing Mill: The transfer bar then enters a series of finishing mills, also called tandem mills, which further reduce its thickness and improve its surface quality. Each mill consists of multiple rolls that progressively reduce the thickness until the desired plate gauge is achieved.

Cooling and Coiling: After the final rolling pass, the plate is typically cooled by water sprays or air jets to prevent warping and promote metallurgical properties. The now solidified steel plate is then coiled or cut into individual lengths, depending on customer requirements.

Plate Straightening and Inspection: If necessary, the steel plates may undergo a straightening process to remove any residual curvature. Additionally, they undergo thorough inspections for dimensional accuracy, surface quality, and other specified characteristics.

Heat Treatment (if applicable): Depending on the intended application, some steel plates may go through additional heat treatment processes such as quenching and tempering to enhance their mechanical properties.

Surface Treatment and Finishing: Steel plates may undergo surface treatments like shot blasting, priming, or painting to improve their appearance and protect against corrosion.

The rolling process is highly controlled and can be tailored to produce steel plates of different dimensions, thicknesses, and grades to meet specific industrial requirements. These plates find applications in various sectors, including construction, shipbuilding, automotive, energy, and manufacturing industries.
