Steel billets Wholesale Market in 2020

In Iran, Mobarakeh Steel, Khuzestan Steel, Chadormelo factories produce crude steel using the electric arc furnace method and perform ingots, especially slabs and sheet metal. Mobarakeh Steel is exclusively responsible for the production of slabs, but other factories of the National Iranian Steel Company and Khuzestan Steel produce all types of blooms, billets and slabs. Isfahan Steel also uses the traditional method of steel production, ie the use of a blast furnace for indirect reduction of iron. At its current capacity, Zobahan only produces bloom. Other small and large workshops across the country also use induction furnaces to reach crude steel. For more information about steel billets Wholesale Market in 2020, visit our site.

How are steel billets made?

Blast Furnace method This is a common method in the world for steel production. In this method, after pelletizing, iron ore is poured into a blast furnace with coke and lime and crude iron or cast iron (with a carbon content of more than 2%) is obtained.

The raw iron is then converted into molten steel in a converter furnace by means of oxygen blowing. Blowing oxygen also reduces the amount of phosphorus and sulfur that are not well absorbed. After reaching the desired chemical composition, the melt is transferred to the continuous casting section with the help of a ladle. And the casting unit is cast and produced as one of the types of steel ingots with the help of continuous melt casting technology.

Direct reduction This method is common in Iran and is done using natural gas fuel in reduction furnaces. The output of the direct reduction furnace is sponge iron, which is commonly used as a briquette. Scrap and used irons are poured into special arc furnaces in special baskets, and then sponge briquettes are added to the kiln with slag materials such as coke, lime, bentonite, and… from above. The charge of the furnace is melted by the heat generated by electric arcs. The chemical composition of the melt is checked again to reach the desired state. After the separation of impurities, the molten steel is taken to the casting unit by means of ladles carrying the molten material. The molten material is poured into a container called a tandish, then it is placed in a round copper mold and placed on a roller, and it is cooled by spraying water. Then, the obtained frozen ingots are cut to the desired lengths. . In this way, all kinds of steel ingots can be produced.

Tunnel kiln method This method is actually the reduction of solid iron with the help of carbon agent. This method is a newer method than the previous two methods. The construction of industrial units with this method is on the agenda in the country, but at present a large manufacturer does not use this method.

Bulk marketing of Steel billets

types of steel billets After the molten raw steel is obtained by using steelmaking in an electric arc furnace (EAF) or converter, the forging process is carried out in two ways: continuous casting and manual (single casting). The method of casting and molding of ingots is very important because the solidification of ingots is done at this stage and the microstructure (internal order) of the piece is formed here and the physical and mechanical properties of other products also depend on this stage.
