Steel slabs have many different variations and one of them is 100mm in diameter. A sheet is a semi-finished steel product with a rectangular cross-section that undergoes one or more processing steps in rolling mills and sheet making to become the final product (sheet steel). In Iran, this product is called steel slabs, pronounced (plate) in English.
The slab is semi-finished steel for the manufacture of steel sheets and functional sheets, and the price is very important considering the quality production of this product in Iran. Most plates are made of carbon steel, but stainless-steel plates are also available. This product is composed of iron, chromium, copper, manganese, nickel, silicon, nickel, molybdenum, and other alloys. Its specifications are specified via standard codes, which are usually engraved on the end of the board. Sheets are rectangular steel products with widths from 650 mm to a maximum of 2000 mm, thicknesses from 200 to 250 mm, and variable lengths from 4 to 12 meters.
The production size of this product depends on the application, the maximum production speed for this product is 230 mm in thickness, 1250 mm in width (one meter and 25 cm), and 12 m in length.
The record market is limited, with approximately 20 million tons of records produced and sold globally each year. Billet, Bloom, and Slab are brands of 22 sheets of steel used to make different types of profiles and steels. Sheets are used in the production of various flat steel products such as sheets, plates, and rolls as well as in the heavy machinery industry. According to the declared standard size, the thickness of this steel plate is very thin, so there may be problems when cutting, so it must be cut with high-capacity equipment.
steel slabs 120 9mm
steel slabs especially "120 cm to 9mm" is one of the other products in this field of business.
Steel slab is one of the semi-finished and unfinished sheet metal profiles, its rectangular cross-sections are available in different sizes, but the most important and most used of these is 230 x 1250 mm.
Export of first-class steel slabs
steel slab and ingots are used as raw material for the production of tapes, welded pipes, coils and plates, and the product is 12 meters long. The images are in front of the bars, and they are distinguished by their shape and their subsequent use in the production of the product. In a way, a bar has a square or circular cross-section and is used to make long sections, while a plate has a rectangular cross-section which, as mentioned above, is used to make flat products. Beds are usually made of carbon steel. But stainless steel is also used to make this product. In general, there are different types of plates. But most of them contain elements like iron, chromium, copper, manganese, molybdenum, nickel and silicon.
different qualities of plates
- Plates come in different qualities, the most famous of which are sp3 and sp5. These two grades belong to the Russian standard GOST380 and are used for the production of plates. Below we mention the difference between sp3 and sp5.
- Sp3 boards have higher toughness than sp5 boards.
- sp3slab is more expensive than sp5slab.
- The content of sp3 alloying elements is less than sp5.
- sp3 plates are typically used to produce small sizes of angles, studs and rods, while sp5 plates are used to produce coils and rods up to size 25.
steel slabs xl
steel slabs are one of the basic materials in producing xl steel sheets and bars. slab production method Although the techniques used to make steel products after obtaining the molten steel are almost the same, there are three main methods of making sheets:
- Blast furnace method.
The blast furnace process is a traditional method of making plates using indirect regeneration. 
Given that Iran has high-quality coal resources, this approach is practical. First, iron ore is put in a blast furnace together with lime and coke to extract pig iron (hot metal). To remove impurities in molten steel obtained from pig iron, crude steel is obtained by removing carbon and adding oxygen. Next, in the continuous casting unit, the melt is poured into the mold by separating the product from the mold and cooling it with a jet of cold water, and turning it into a frozen bar. Finally, the desired plate length can be achieved by different cuts.
- Electric oven
Two methods of steel production are the use of electric furnaces and remelting of scrap steel, which involves pouring iron baskets into the furnace. Due to the scarcity of scrap sources in the world and the constant rise in prices over the past few years, iron fungus is also melted in the furnace along with the scrap in this method. 
Therefore, add iron sponge and slag-forming materials such as coke, bentonite, lime, and other additives to the melt from the top of the furnace, while melting scrap, after sampling, by adding oxygen, impurities, especially carbon, to the furnace. melt oxidized. Finally, it is produced by homogenizing molten steel. In the casting unit, molten steel is poured into water-cooled copper molds, which are then transformed into frozen steel ingots by spraying cold water.
steel slabs 6x6
The other size related to the steel slabs is 6x6. Worldwide, the plate widths are greater than 160 mm. But usually beds made in Iran are between 2000 and 650 mm wide and 200 to 250 mm thick. The length of the plate is 4-12 meters. But the most common plate size is 1200x1250x230 mm. Sometimes you may see names next to steel product names that you do not understand. 
The C-plate is called the plate used to make the heating plate C or HC. HC hotplates are characterized by thicknesses from 5 to 6 miles and widths from 1300, 1350, 1400, and 1450 mm. Passing the properties and quality specifications of the steel plate is the basic condition for the subsequent steel plate production. Therefore, after the plate production process, these products go to the quality control department to be inspected for the following three properties. * No cracks, inclusions, pores, and shrinkage * No hollowing, swelling, and bending * Has a smooth surface, no scaling In general, molten steel or crude steel is produced in three ways. But the technology used to produce tickets at different stages after the molten steel is obtained is almost the same. Sheet casting is performed by continuous and manual casting methods after obtaining crude steel or molten steel. 
In barre continuous casting, also known as the CCM method, molten steel is poured into a copper mold at a certain speed. During the freezing process, the frozen plate portion is removed from the die end at a rate corresponding to the filling rate. This method of fabricating the beat hall is fast and more common than manual methods because of its cost-effectiveness.
steel slabs 80
The steel slabs with the 80 cm length are a little odd for this product but we can say that we can cut the slabs into this size as well. The main use of plates is to get different steel plates. In fact, plates, and ingots are not much used. To make any kind of steel plate, the plate must first be heated to a certain temperature. The products sold after plate rolling are boards or hot plates. The same heating plate produced in operation is converted into other oil plates, galvanized plates, etc. 
Mild steel is a type of low carbon steel and is actually called "low carbon steel". The carbon content of this steel is typically 0.05 to 0.25% by weight, while high carbon steels are usually described as having a carbon content of 0.30 to 2.0%. With the title cast iron. Mild steel is not alloy steel, so you will not find significant amounts of chromium, molybdenum or other alloying elements in this type of mild steel. Due to its relatively low content of carbon and alloying elements, there are several properties that distinguish it from carbon and higher alloy steel. Less carbon means low carbon steel is more ductile, machinable, and weldable than carbon steel and other malleable materials, but it is almost impossible to harden and strengthen by heating and quenching. This steel contains a lot of iron and ferrite, which makes it magnetic. 
The lack of alloying elements in this steel means that the iron in mild steel can oxidize (rust) if it is not properly coated. However, small amounts of alloying elements make low-carbon steels more economical compared to other steels. The ability to weld and twist this steel makes it a popular steel choice for consumers.
thin steel slabs
steel slabs have many different byproducts as well. One of the thin products of steel slabs is bars and steel sheets. Manufacture and sale of steel plates in various sizes and thicknesses. The thickness of the steel plate is defined as about one millimeter to over 50 millimeters. Thin steel plates are divided into 1.2 to 75.2 mm, medium-sized steel plates from 3 to 7.4 mm, and thick steel plates from 5 to 200 mm. Sheet steel is used in the construction industry, manufacturing installations and equipment, bridge construction, reinforcement columns, and other industries. This metal product is divided into different types such as blackboard, ribbed plate, stain board, oil plate, color plate, galvanized plate, and so on. Thick plates are mostly used for the manufacture of large pipes and API pipes. The plate is the main material for the production of various types of steel. They use plates to make plates. The plate is composed of iron, carbon, nickel, molybdenum, copper, and chromium. This bar has no holes and no cracks and is suitable for roller production of various strips, pipes, and plates. To make bars, iron ore is smelted in blast furnaces or other common methods and converted into rectangles with a thickness of 160 mm. Carbon steel 
This group is the most common type of steel, accounting for 90% of production. Carbon steel is divided into three groups based on the carbon content of the metal: mild steel (up to 0.3% carbon), medium carbon steel (0.3% to 0.6%), and high carbon steel (above 0.6%) divided. alloy steel These steels contain elements such as nickel, copper, chrome, or aluminum. The addition of these ferrous and non-ferrous metals to steel has a great effect on improving strength, ductility, corrosion resistance, and machinability. Stainless steel The composition of this steel contains 10% to 20% chromium alloy, so it has high corrosion resistance.
