Steel Ingot A steel ingot is the first product obtained from iron ore through steelmaking processes and is produced in the form of rectangular blocks with dimensions suitable for handling and transportation. The length of an ingot is typically more than 2 meters, and it is produced as a solid metal. This type of ingot is among the most widely used semi-finished steel products in the world and is available in various forms. An important aspect of steel ingots is their shape and size, which play a crucial role in subsequent forming processes. Another important factor is the casting method and the solidification of molten steel in molds, as these determine the physical and mechanical properties of the product. In large steel industries, ingots are classified into blooms, billets, and slabs, each with different dimensions and characteristics used for producing specific steel products. Bloom A semi-finished steel product with a large square or rectangular cross-section, used for producing heavy steel sections. BilletA semi-finished steel product with a smaller square cross-section, used for the production of rebars and wire rods. Slab A semi-finished steel product with a wide , flat rectangular cross-section, used for the production of steel plates and coils. مطالعه
Z-profile Z-profile Profiles manufactured with a Z-shaped cross-section are also commonly known as Z purlins and are classified as open sections. The production process for these profiles is relatively complex and is carried out using the hot rolling method. Z-profile sizes and dimensions are available in a wide range and are manufactured based on market and customer requirements. The maximum steel grade used for these profiles is up to ST52. Z profiles are produced using hot-rolled (black) sheet or cold-rolled (oiled) sheet. The sheet sizes can be 16, 18, 20, and 22, with thicknesses of 22, 2.5 , and 3 mm3 mm. In the market, Z profiles are commonly referred to as Z16, Z18, Z20, and Z22. The number after “Z” indicates the height of the Z profile. Another characteristic of Z profiles is the presence of slotted punching (commonly known as kidney-shaped holes).
