It is intermediate and semi-finished steel obtained by ingot rolling process or continuous casting process. The cross-sectional area of the slab is not square but rectangular and is used as a raw material for the manufacture of flat rolled products including coils and hot rolled sheets. This article will introduce slabs, their production methods, applications, and some key points related to slabs. Slabs as rectangular steel products with widths from 650mm up to a maximum of 2000mm, thicknesses from 200 to 250mm and variable lengths from 4 to 12 meters to produce various steel products such as sheets, plates, and coils as well as heavy duty Machinery Industry. What is a slab? A slab is a semi-finished steel product with a rectangular cross-section that goes through one or more processing steps in rolling mills and sheet manufacturing to become the final product (steel plate). In Iran, this product is called Takhtal, pronounced (slab) in English. 
Slab is a semi-finished steel in the manufacture of steel plates and functional plates, and its price is very important considering the quality production of this product in Iran. Most slabs are made of carbon steel, but stainless-steel slabs are also available. Iron, chromium, copper, manganese, nickel, silicon, nickel, molybdenum, and other alloys make up this product. The board's end is typically engraved with standard codes that describe its parameters. Some criteria are Steel table standard size Slabs are rectangular steel products with widths ranging from 650mm to a maximum of 2000mm, thicknesses from 200 to 250mm and variable lengths from 4 to 12 meters. The production size of this product depends on the application, the maximum production speed of this product is 230 mm thickness, 1250 mm width (one meter and 25 cm), and 12 meters long. The slab market is limited, with approximately 20 million tons of slab produced and sold globally each year. Slab application Billet, Bloom and Slab are brands of 22 steels used to manufacture different types of profiles and steels. Slabs are used in the production of various flat steel products such as sheet, plate, and coil, as well as in the heavy machinery industry. 
According to the declared standard size, the thickness of this steel plate is very low, so there may be problems when cutting it, so it needs to be cut with high-capacity equipment. Slab production method Although to produce steel products, the techniques used after obtaining the molten steel are almost the same, there are three main methods of producing slabs: 1. Blast furnace method, Kanwar Tor (traditional method) The blast furnace method is a traditional method of producing slabs by indirect regeneration. Considering Iran has high-quality coal resources, this approach is a practical one. First, iron ore is put into a blast furnace along with lime and coke to extract pig iron (hot metal). To remove impurities in molten steel obtained from pig iron, raw steel is obtained by removing carbon and adding oxygen. The melt is then injected into the mould in the continuous casting unit after the product has been removed from the mould and cooled using a cold-water jet. and turning it into a frozen ingot. Finally, the desired slab length can be achieved by different cuts. 2. Electric oven Two methods of steel production are the use of electric furnaces and scrap steel remelting, which involves pouring iron baskets into the furnace. 
Due to the scarcity of scrap sources in the world and the constant increase in its price over the past few years, sponge iron is also smelted in the furnace together with the scrap in this method. Therefore, while smelting scrap iron, add sponge iron and slag-forming materials such as coke, bentonite, lime, and other additives to the smelting from the upper part of the furnace, after sampling, by adding oxygen, impurities, especially carbon, in the melt oxidized in. It is finally made by homogenising molten steel. In the casting unit, molten steel is poured into a hydrothermal copper mold, which is then turned into a frozen steel ingot by spraying cold water. 3. Induction furnace Induction furnace methods are costly due to the use of electricity, electrodes, and additives, on the other hand, these furnaces have two problems that prevent them from being used for steelmaking in Iran. The first problem is that induction furnaces do not control oxygen well, which can lead to defects in the product, as the oxidation of ferroalloys occurs due to the dissolved oxygen hookah in the melt. The second problem with this method is the dephosphorization and desulfurization of the induction furnace. Although in the world they use the blast furnace method to produce crude steel and slabs. Slab production plants in Iran Due to the special status of slabs in steel products, they are sold at Isfahan Ironworks, Khuzestan Steel Works, Hormozgan Steel Company, Mobarak Isfahan Steel Company and Chadomello Steel mill production, Hormozgan Steel Works is known for producing slabs. 
The mills produce slabs between 180 and 300 mm thick and in lengths 4, 6, 10 and 12. As in recent years, the product has been produced according to global standards and exported to various countries in Asia and even Europe.
