Hot rolled sheets
In the process of hot rolling, the steel ingot after reaching the desired temperature, which is usually higher than 1100 ° C, in rolling furnace, passes through several sets of rotary rollers and, with successive reductions in the cross section, deformed into shape and it turns into the desired shape. Hot-rolled products are products that are delivered to the thickness of the rolling slab at high temperature and are available in either coil (roll or coil) or sheet (plate) as rolling-edged or modified edges.
Despite the fact that the surface of hot rolled sheets in the rolling process is improved by deformation mechanisms, but due to the nature of hot rolled heat, they are exposed to non-shiny surfaces in contact with the atmospheric atmosphere, which is why they are known for the black sheets in market.
Hot-rolled steel sheets are medium and high carbon steel sheets that are rolled up and are slightly tensile, which has abrasion resistance and high strength properties.
In the process of producing melting and slab in steel making and casting, the necessary controls are carried out on chemical analysis and impurities, and in the process of sheet production in a hot rolling method, the quality indices such as thickness, width, profile, surface conditions, edges and packaging are controlled and evaluated. Finally, the mechanical properties (strength) of the sheet in the laboratory are tested and confirmed.

Usages and applications
Cement industries (anti-abrasive sheets used in cement industry machines.) – Tile and ceramic industries (used to make tile and ceramic tiles that should be anti-abrasive and also have high strength). – Supplies Homemade (the sheets are used for the manufacture of knives and kitchen utensils and slaughterhouses and butchers). – Mining industries (for the purpose of making the envelope of loaders and blades for loaders, bulldozers, blades for grader and mechanical bill.) – Industry (used to make conveyor chains and some washers and cutting blades and brakes). – Agriculture (making some parts of agricultural machinery and some blades working on land and with dirt).- Military and military equipment (for the construction of some parts of military machinery and military equipment, for the construction of personal carrier and some bulletproof sheets, etc.) – automotive and automotive industries (from the above sheets for making some of the equipment and Automobile parts are widely used in manufacturing automotive seat belt locking and belt locking parts and making some parts of car seats and manufacturing disc components and clutch plates, door lock locks and door lock mechanism and seat mechanism. Making conical washers and stepped gaskets and many other parts of the car.) – road and rail transport (for the construction of some parts of road and rail machinery and some of the wagon parts and trains are used extensively).
