billet bloom slab manufacturing order

Larger than blooms, billets, and slabs in both size and shape, ingots are very massive casting products. Another casting product is billet. A relatively pure substance, usually metal, is cast into an appropriate shape for subsequent processing to create an ingot.

To generate a functional end product, ingots typically require a second shaping process, such as cold/hot working, cutting, or milling.We can give you access to the suppliers of these products. Order it from us for affordable costs.

The continuous casting technique greatly increased the efficiency of casting metals including brass, steel, aluminum, and copper with the aim of expediting the manufacture of metal slabs and bars. Any casting company can increase productivity by using the straightforward four-step process known as continuous casting.

Continuous casting, also known as strand casting, is the procedure used to solidify molten metal into a billet, bloom, or slab that is “semifinished” and ready for rolling in the finishing mills. In the modern industrial period, a machine known as the CCM is typically used to produce billets (continuous casting machine).

This method is most typically used to cast steel (in terms of tonnage cast). Despite being repetitious and laborious, the process is much more efficient than the outdated technique of casting ingots and has the potential to save you both time and money. Your key to success is using the continuous casting technique.

Manufacturers used ingot casting to create slabs and bars before continuous casting became extremely popular. Sadly, 5 percent of the ingots produced in the majority of manufacturing are destroyed due to cracks and butt deformations brought on by generated stress.


Continuous casting allows you to completely optimize your production’s cost effectiveness because absolutely no materials are wasted during the process. This is the continuous casting process’ greatest benefit. Contrary to ingot casting, the bars and slabs produced are always solid and free of cracks, so you never have to discard any damaged items.

Increasing efficiency is one of the best ways to cut costs, and continuous casting allows you to produce huge quantities of metal slabs and bars more quickly than you could with ingot casting, which requires you to pour each product manually.

Large, hefty blocks or rounds produced from a primary metal or during a recycling process are known as metal billets, slabs, and blooms. In the processes of extrusion, forging, rolling, and other metal-processing operations, they serve as raw materials or feedstock.

Round, rectangular, or hexagonal ingots or cast, semi-finished stock with a cross-section suitable for further processing are referred to as metal billets. Billets, also known as bar stock, are offered for sale as cut-lengths or coils. Metal slabs are rolled ingots that are flat, semi-finished, and have a specific cross-dimensional section. Large, square sections known as metal blooms serve as a transitional stage in the rolling process.

Making of Metal Billets, Slabs, and Blooms

There are numerous processes that can be used to create and modify metal billets, slabs, and blooms; these processes are categorized. The processes include casting, joining and assembly, deformation, material removal, heat treating, and finishing.

In casting procedures, molten metal is poured into a mold cavity, where it solidifies and adopts the shape of the cavity. Stock shapes can be produced continuously using continuous casting processes.

Welding, soldering, brazing, fastening, and other processes that join parts permanently or semi-permanently to create a new entity are examples of joining and assembly processes.

Metal forming, roll forming, extrusion, forging, and sheet metalworking processes are all examples of deformation processes. They employ plastic deformation, where deformation is brought about by external compressive forces greater than the material’s yield stress.


In order to achieve the desired shape, material removal processes remove excess material from the workpiece. They consist of machining operations, abrasive machining, and novel laser- and electron-beam-based techniques.

Annealing, quenching, tempering, aging, homogenizing, solution treating, and precipitation hardening are some of the heat treating procedures. The metal stock’s strength, ductility, hardness, machinability, and formability are changed by heat treatment.

To give metal shapes the proper surface quality, texture, corrosion resistance, and fatigue resistance, finishing techniques modify the surface’s structure. Finishing procedures include polishing, burnishing, peening, galvanizing, painting, oiling, waxing, lubricating, plating, and coating.

ingot vs billet

The semi-finished MS Billets are used in roll mills to create lengthy goods like wire rods. Forge shops and machine shops frequently employ steel billets to produce technical goods and as a feedstock for seamless tubes. On the other hand, large-sized castings made at a foundry are typically known to as MS Ingot. Ingots don’t have any set dimensions.

The molten metal from the blast furnace is poured into huge, cylindrical ladles at steel mills. In general, billets are smaller in size. A casting is referred to as a billet if its cross-section is square. The cross-sectional area of a billet is less than 36 square inches. Let’s examine the differences between MS Billets and MS Ingots:

In MS Ingot casting, the liquid steel fills the cast iron mold from one side while remaining static by flowing via a refractory channel. Refractory particles chip off from the channel and mix with the liquid steel in this process, leading to undesirable inclusions in the ingot that result in rolling defects.

In contrast, continuous casting technology used in MS Billet casting allows liquid steel to flow from a furnace to a caster through a copper mold. Cooling occurs and the water in the mold oscillates at a predetermined rate. For the liquid steel to crystallize into equiaxed crystals, regulated cooling, oscillation, and pause is carried out.

The separation of chemical alloys occurs during the solidification phase of the MS Ingot. Various parts of the ingot have different chemical characteristics. However, chemical alloys are evenly distributed in MS billets due to continuous casting.


Very dangerous flaws such a blowhole, central piping, cracks, and inclusions are discovered in MS Ingot. There are no such flaws in MS Billets. Additionally, because of pouring faults brought on by the poor mold surface, the MS Ingot’s surface developed scabs and laps. The smooth copper mold surface is what causes MS Billets’ surface to be clear and free of scabs and laps.

When MS Ingots are solidifying, the liquid steel produces gas that becomes trapped in the steel and creates cavities and blowholes. Since the gas in the liquid steel escapes during the solidification process due to continuous casting technology, such accidents cannot be observed in MS Billets.

Due to a lack of tensile characteristics, TMT bars manufactured from MS Ingots exhibit inconsistent tensile strength and elongation. But because of the great tensile strength and elongation, TMT bars made from continuous-cast MS Billets exhibit an amazing consistency of characteristics.

billets and slabs are made by which casting

Intermediate castings produced in a steel mill are referred to as semi-finished casting products because they require more processing before being considered finished items. Ingots, blooms, slabs, and billets are the different types. Ingots are the most common.

Ingots are huge castings that have a rough texture and are designed for storage and transport. In most cases, the form takes the form of a rectangle or square that has been generously filled in. They are slanted, typically with the wider end on the bottom.

Blooms were slag-filled iron castings that were poured in a bloomery prior to being turned into wrought iron in the era when commercial wrought iron was produced. Blooms are pieces of steel that are formed during the era of commercial steel production by a first pass of rolling (in a blooming mill) that reduces the ingots down to a lower cross-sectional area, but that is still bigger than 36 in2 in size (230 cm2).

Blooms are typically subjected to additional processing, which may include rotary piercing, structural shape rolling, or profile rolling. Final goods such as structural forms, rails, rods, and seamless pipes are examples of common end products.

A piece of metal that is less than 36 inches in length and has a cross-section that is either round or square is called a billet (230 cm2). Billets can be produced directly through processes such as continuous casting or extrusion, or indirectly through the process of hot rolling an ingot or bloom.


Additional processing steps include profile rolling and drawing on the billets. Bar stock and wire are both included in the final products.The production of short circular tubes as billets can also be accomplished using centrifugal casting. This is typically done in order to establish a precise metallurgical structure.

They are frequently put to use as cylinder sleeves, in which case both the inner and the outer diameters are ground and the length is machined. Because their dimensions do not change greatly, casting goods that contain them are not always considered to be in the semi-finished stage.

A pure copper bar of approximately 8 inches (200 millimeters) in diameter and 30 feet (9.1 meters) in length is referred to as a billet in the process of producing copper.

Slabs will have rectangular cross sections, and they are utilized as the starter metals in the production of flat products such as steel plates and hot rolled coils. Slabs also have the ability to be sliced into strips.

Blooms are pieces of steel that are produced during an intermediate stage that are formed as a result of a first pass of rolling that reduces the cross sectional area of the ingots. In most cases, the blooms undergo additional processing by means of rotart piercing, structural shape rolling, and profile rolling. The structural shapes, rails, rods, and seamless pipes that are produced are all examples of common final products.

A piece of metal that has a cross section that is either round or square might be called a billet. Directly, billets can be made by the process of continuous casting or extrusion. Indirectly, they can be made through the process of hot rolling an ingot or bloom. Additional processing includes rolling the billets into profiles and drawing them. Bar stock and wire are included in the final products.

billet in manufacturing

It is the shape of the metal that is employed in the manufacturing process that is referred to as a “billet,” not the manufacturing method itself. Billets are lengths of solid metal that have square or circular cross-sections at their midpoints.

They can be constructed using almost any kind of metal or alloy and scaled to virtually any size in order to fulfill the requirements of the component and the manufacturing process.Continuous casting or hot rolling are the two production procedures that can be used to create billets.

After they have been shaped into their preliminary form and size, they are typically shaped into their final part form and size through machining methods (such as CNC machining), which means that excess material is removed from the workpiece. Once they have been shaped into their preliminary form and size, they are generally machined into their final part form and size.

When compared to other techniques of production, billet manufacturing has a number of advantages, including the following:

  • Even in little quantities, it offers a good value.
  • It allows for a high degree of precision in the finished products of manufacturing.
  • It results in pieces that have an exceptional degree of structural stability.
  • Short lead times are achieved in the processing of raw materials and the production of finished items.

Metal is heated, melted, poured, and then cooled as part of the casting production process, which is a type of manufacturing procedure. After the metal has been brought to a molten condition, it is poured into a mold that has already been constructed.

The metal must be allowed to cool and harden once it has been poured into the mold. At that time, it is able to keep the shape of the interior of the mold while also being able to be withdrawn from the mold.

When compared to other techniques of production, cast manufacturing has a number of advantages, including the following:Sand casting is an example of an application in which it is cost-effective to produce a limited quantity (die-casting).It can work with a wide range of part dimensions and configurations.

It is possible to create parts that are very close to their final form, which reduces the amount of waste produced and removes the requirement for post-processing.
