There are different types of steel ingots, each with a different shape, alloy, and price. Steel ingots are usually produced with square and rectangular cross-sections of different dimensions and lengths of 2 to 12 meters .
Steel ingots, or iron ingots, are one of the most important and basic products in the steelmaking industry. Steel ingots are manufactured in three forms: billet, slab, and bloom, each of which is used to produce certain materials..
| Steel ingot type | Appearance | Approximate dimensions | Chemical composition | Applications |
| Billet | Circular or square cross-section | Length: 6 to 12 meters | Carbon and low alloy steel | Production of rebar, wire and wire |
| Bloom | Larger square cross-section | Length: 6 to 12 meters | Carbon and low alloy steel | Rails, beams, cans and shields |
| Slab | Rectangular cross-section | Width: 0.6 to 1.5 meters | Carbon and low alloy steel | Production of metal sheets, pipes |
| Ingot | In the form of a large block | Different dimensions | Different steel compositions | Remelting, casting |
| Sharp | Square or rectangular cross-section | Various lengths and widths | High alloy steel | Production of special industrial parts |
Types of steel ingots
Billet
Billets are produced with a longer length than other ingots. Billets are also known as ingots. Billets have a square or circular cross-section and their dimensions are 15 cm or less. Billets are made by direct extrusion casting or by ingot rolling .
In Iran, according to Russian standards, steel billets are in grades 5 sp. and 3 sp They produce. To produce rebar from grade 5 sp They use grade 3 sp to make iron beams and angles. They use.
Bloom Ingot
Bloom is also known as a billet. Blooms are billets that are wider than15 cm or their cross-sectional area is less than 230 It is square centimeters. Billet and bloom are in the same group. Bloom is used to make rails, bridges, gutters, cans, beams, etc.
What is a slab ingot?
Unlike billet and bloom ingots, the cross-section of a slab ingot is rectangular. The slab is 230 mm thick and 0.6 to 1.5 meters wide . Slabs are used to make steel sheets and sheet products such as pipes and profiles.
Steel ingot (ingot)
Steel ingots are produced in the form of a large, bulky metal block. Ingots are obtained in the early stages of steel production and are used for remelting and casting industrial parts. Their chemical composition can be plain steel or alloy steel, depending on the need. Ingots usually have a trapezoidal cross-section with large dimensions and a length of two meters.
The difference between billet and bloom
Ingots with dimensions of 100 , 125 , 130 , 150 , and 160 are called billets, and ingots with dimensions of 250*250 , 200*200 , and 180*180 are called blooms. Blooms or ingots are produced by casting or rolling ingots. One of the most important differences between billets and blooms is the difference in their appearance .
Another difference between billets and blooms is that these two products differ in terms of dimensions. To produce blooms from the casting or rolling process, the size of the ingots is changed. Another difference between billets and blooms is their length, which is longer than the ingot and can reach up to 12 meters. This feature of blooms is used to produce products such as beams .
The difference between ingot and billet
Billets, like blooms, are longer than ingots. The cross-sectional shape of this product is different from that of ingots. The cross-sectional shape of billets is rectangular or circular, which is more suitable for producing rebar and beams .
The difference between ingot and slab
The trapezoidal cross-section of the ingot is converted into a rectangular slab by rolling or casting, and the length of the final product increases to about 6 or 12 meters. This feature is suitable for the production of seamless sheets and pipes. Seamless pipes are also called Mannesmann pipes .
