Hot Rolled Steel Sheet

Hot Rolled Steel Sheet One of the most widely used types of steel sheets is hot-rolled steel sheet (commonly referred to as black sheet in the market). This type of sheet is informally known as “black sheet” due to its dull, non-reflective surface appearance, which results from the formation of mill scale during the hot-rolling process. Its typical surface color is matte gray. Hot-rolled steel sheet (commonly known as black sheet) is produced through the hot rolling process and should not be confused with hot-dip galvanized steel.This type of steel is typically manufactured from grades such as ASTM A36 and ASTM A1011. During production, steel slabs are heated in a reheating furnace to temperatures of approximately 1,200–1,280°C.In the next stage, the heated material passes through a series of rollers where the rolling process reduces its thickness to the required dimensions. During this stage, descaling is performed to remove surface scale (iron oxide) formed at high temperatures.Finally, after passing through finishing stands and a run-out cooling table, the steel strip is coiled and formed into hot-rolled steel coils. Applications of Hot-Rolled Steel Sheet (Black Sheet)Hot-rolled steel sheet (black sheet) is used in various industries. Some of its most common applications include the following:automotive body structureautomotive floor pan steel sheeWelded pipesTypes of structural steel sectionsTanker fabricationship construction

Heavy I-beam

Heavy I-beam The most widely used type of beam in the construction industry is the wide-wing beam, which has a shape similar to an H. For this reason, it is also known as a "hash" beam. This type of profile is produced in light and heavy versions, which have different uses. H beams, with a wider wing design, are stronger and heavier than conventional models. This type of beam is usually used in the construction of columns, bridge beams, buildings and engineering structures. The height of heavy beams is equal to their width. The web thickness of this type ranges from 6 to 19 mm and the flange thickness is 10 to 36 mm, which is thicker than the light type. As a result, it has greater resistance and is also more expensive.

Galvanized steel sheet

Galvanized steel sheet Galvanized steel sheet is one of the most common types of steel sheets. It is typically produced through the cold-rolling process and subsequently coated with zinc in a galvanizing process (commonly referred to as zinc coating or galvanization). The zinc coating prevents the steel sheet from oxidizing (rusting). As a result, this type of sheet exhibits high resistance to corrosion. From a technical standpoint, the stated thickness range appears unusually high for galvanized steel sheets (which are typically thinner). However, based on your text, the accurate English translation is:The thickness of galvanized steel sheets ranges from 6 to 18 mm, with lengths between 2 and 6 meters, and an approximate weight ranging from 8 to 30 kilograms.If you would like, I can also provide a technically corrected version based on standard industrial specifications.This type of sheet is also produced in another form, known as hot-dip galvanized steel. It is obtained by applying a galvanized coating to the surface of cold-rolled steel sheet (commonly referred to as oiled sheet) during the hot-rolling process. These sheets are resistant to impact, corrosion, and rust.Applications of Galvanized Steel Sheet Galvanized steel sheet is used in the following industries:Water transmission pipesCabinetWater storage tankssteel structure roof

Direct Reduced Iron (DRI)

Iron ore pelletPelletizing is a process that converts fine particles of raw materials (concentrate) into dense, compact agglomerates. Pellets are the final product of the pelletizing process and serve as a key feedstock for hot metal production in blast furnaces and for sponge iron production through various direct reduction methods. Pelletizing MethodsIn general, pellets are produced using two main methodsCone (Rotary Drum)Disc PelletizerThe main raw material for producing iron ore pellets is iron ore concentrate, and the particle size of the concentrate used should be below ‎45 microm‎. Additives and binders such as bentonite, hydrated lime (lime slurry), organic materials, lime, cement, and water are also used in the process. Direct Reduced Iron (DRI)Sponge iron, also known as porous pellets, is produced through the direct reduction of iron ore pellets and has a high grade, typically ranging from 34% to 95%. The direct reduction process removes oxygen from the iron ore and converts it into a porous, sponge-like structure—hence the name “sponge iron.” It is usually produced in lump or pellet form. In addition, it can be produced in a compacted form known as briquettes, called Hot Briquetted Iron (HBI). Applications of Direct Reduced Iron (DRI)Direct Reduced Iron (DRI), also known as sponge iron, has many applications. Its most important use is as a substitute for steel scrap in induction furnaces, where it is used to produce billets and other steel products. In these furnaces, up to 50% of the charge can consist of DRI in place of scrap.

Deformed Wire Coil

Deformed Wire Coil Along with civil projects, from supply to quality control Rebar coils are tightly wound coils made of reinforcing steel bars. When their surface is ribbed , they are referred to as deformed wire coils. This type of rebar is classified into two grades: A2 and A3. The production process of wire coils is such that after the rebars are manufactured, they are coiled using special equipment. The steel used for these rebars is produced through steelmaking processes such as open-hearth furnaces , electric arc furnaces, and converters. This product is made from billet ingots by the hot rolling process and is then converted into various wires through cold drawing operations. Finally , the wire is formed into coils. The inner diameter of the coils is about 85 mm and their weight is approximately 22,000 kilograms. Applications of Deformed Wire CoilDeformed wire coils are used in various industries , including the following:Construction industryFabrication of trusses and joistsWire rope productionBarbed wire productionManufacture of wire mesh, fencing, and gabionsManufacture of nails, screws, and rivetsManufacture of metal chainsElectrode manufacturing and welding industryProduction of free-cutting wire rodsSpring manufacturing industryDownstream steel industries and steel conversion/processing industries

Bloom

Steel Bloom A bloom is one of the types of steel ingots, also known as a billet bar, and when molten steel is produced from raw materials, it is cast into bloom molds.This product has a width of more than 15 cm and a cross-sectional size larger than that of a billet (i.e., greater than 23 cm). Blooms are mainly used for the production of industrial rebars and are also applied in manufacturing products such as structural profiles , I-beams, channels, and similar sections. Steel blooms are produced in different sizes in steel plants. After solidification, the blooms undergo a cooling stage and are then transferred to rolling mills. In the rolling mill, the blooms enter the rolling line and are plastically deformed. Finally, various finished steel products are produced from these blooms.
