What is semi-finished steel?

Semi-finished steel is an intermediate steel produced in a foundry. It needs further processing before being processed into finished goods. It is used in iron & steel rolling mills for production of finished products.

Why do they call it pig iron?

The common mold shape that is used for ingots was with a branching structure formed within sand. This configuration is similar to the look of a litter of piglets suckling on a sow. Once the metal has hardened and cooled, the little ingots or “pigs” are broken into a thinner runner, hence the name “pig iron.”

What is the finished product of iron ore?

Iron ore is one of the most abundant elements on Earth, and one of its primary uses is in the production of steel. When combined with carbon, iron changes character completely and becomes the alloy steel. iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.

What is pig iron produced in?

blast furnaces
Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces. Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg. The vast majority of pig iron is produced and consumed within integrated steel mill complexes.

Which of the following is not a semi-finished steel product?

Slabs are usually further processed via flat rolling, skelping, and pipe rolling. Common final products include sheet metal, plates, strip metal, pipes, and tubes. Slab are mainly produced through blast furnace route. One of the reasons to preferably produce slab through BF route is to achieve high quality.

What finished steel products?

The products made by the steel industry share the designation of finished steel products. This means that they are tradable products, i.e. they have acquired a form tailored for the steel industry’s customers e.g. the engineering and construction industries.

How is pig iron converted into cast iron?

CAST IRON IS MADE FROM PIG IRON BY MELTING PIG IRON WITH IRON SCRAP AND COKE AND BY PASSING HOT AIT BLAST INTO THE MIXTURE. CAST IRON HAS 3\% CARBON CONTENT LOWER THAN PIG IRON. CAST IRON IS HARD AND BRITTLE.

Why is the product of the blast furnace called pig iron?

The iron mass was then hammered to remove the slag, yielding wrought iron. Increases in the height of the furnace, coupled with mechanical bellows for introducing greater amounts of air into it, allowed the higher temperatures needed to produce a high-carbon iron known as cast, or pig, iron.

What is the product of iron?

Iron ore, for example, Vale’s main product occurs as oxides, carbonates, sulfides and silicates, being the most abundant oxides and greater commercial interest. Our ore, for example, consists mainly of oxides hematite (Fe2O3) and magnetite (Fe3O4).

How is pig iron converted to steel?

Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron (the iron created in the blast furnace) is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.

What is billet iron?

Billets are made by using sponge iron along with cast iron in induction furnace. The molten metal is given shape of billets (100mm. -100mm) with length of 6 metre each by continuous casting machine (CCM) . BFCL has a manufacturing capacity of 1 lac MTPA.

Is pig iron the same as hot metal?

Iron making is the process of Reduction of iron ore using the relevant reducing agent (Reductant). HOT METAL (LIQUID IRON): It is the hot, liquid, metallic iron product obtained upon reduction of iron ore (normally in Blast Furnace or in Corex Furnace). It is called Pig or Pig Iron because of its typical humpy shape.
