Steel billets domestic market in 2021

The term steel is used for iron alloys that contain between 0.025 and about 2% carbon. Alloy steels are often associated with other metals. The properties of steel depend on the carbon content, the heat treatment and the alloy metals it contains.

What is a steel billets?

Steel with up to 0.2% carbon is used to manufacture wire, pipe and sheet steel. Steel has an average carbon content of 0.2 to 0.6 percent and is used in the manufacture of rails, boilers and components. Steel with 0.6 to 1.5 percent carbon is hard and is used to make tools, springs and cutlery. Iron contamination and steel production The iron that comes out of the blast furnace is called cast iron, which contains amounts of carbon, sulfur, phosphorus, silicon, manganese, and other impurities. Two goals are pursued in steel production:

Burning cast iron contaminants.

Adding certain amounts of alloying agent to iron Manganese, phosphorus and silicon are converted into oxides by air or oxygen in molten cast iron and released as slag in combination with a suitable melt. Sulfur enters the slag as sulfide and carbon burns to form carbon monoxide (CO) or carbon dioxide (CO2). When the main impurity is manganese, an acid melting aid, usually silicon dioxide (SiO 2). The inner wall of a furnace from which steel is made is usually covered with bricks made of auxiliary material. This coating will absorb some of the oxides that need to be removed.

An open furnace process is commonly used to remove contaminants. This furnace has a plate-like container that can hold 100 to 200 tons of molten iron. On top of this shell is a concave roof that reflects heat to the surface of the molten metal. A strong stream of oxygen is passed through the molten metal to burn off the impurities. In this process, contaminants come to the surface of the liquid due to heat transfer in the liquid and diffusion, and the refining process takes several hours, although some of the iron that is collected and returned to the blast furnace is oxidized.

The impurities oxidize very quickly and when gaseous products such as CO2 are released they stir the molten mass so that the iron rises to the bottom of the container. The temperature of the molten mass reaches almost the boiling point of iron without the use of external heat, and at such temperatures the reactions are extremely rapid, the whole process being completed in an hour or less, and usually a uniform, good quality product is obtained.
