SBQ Steels produces both basic grade as well as foundry grade suitable for steel producers and foundries respectively.
The Special Bar Quality Alloy Steel, the final product, will mainly be used in auto & auto ancillary industry, viz - Forgings, Heat Treatment Steels, Ball Bearing Steel, Engineering Sector, Components & Seamless Pipe manufacturing sector and as well as Construction steel consisting of Structural Steel/RE-bars.
Pig iron is the intermediate product of smelting iron ore with coke, usually with limestone as a flux. Pig iron has very high carbon content, typically 3.5–4.5%, which makes it very brittle and not useful directly as a material except for limited applications.
Pig iron comprises three main types: Basic Grade Pig Iron, used mainly in electric arc steelmaking, Foundry Grade Pig Iron used mainly in the manufacture of grey iron castings in cupola furnaces, and Nodular Pig Iron (SG) used in the manufacture of ductile iron castings. Pig iron contains at least 92% Fe. Other constituents are typically:
|Pig Iron||Carbon (%)||Silicon (%)||Manganese (%)||Sulphur (%)||Phosphorus (%)|
|Basic Grade||3.5 - 4.5||1.5 Max||0.5 - 1.0||0.05 Max||0.12 Max|
|Foundry Grade||3.5 - 4.5||1.5 - 3.5||0.5 - 1.0||0.05 Max||0.12 Max|
|SG Grade||3.5 - 4.5||0.05 Max||0.05 Max||0.05 Max|
Billet is a section of steel used for rolling into bars, rods and sections. Billets can be directly produced by continuous casting.
Special Bar Quality Alloy Steel(SBQ)
SBQ represents a wide variety of higher-quality carbon and alloy bars that are used in the forging, machining and cold-drawing industries for the production of automotive parts, hand tools, electric motor shafts and valves. SBQ or Engineering Steel generally contains more alloys than merchant quality and commodity grades of steels bars, and is produced with more precise dimensions and chemistry.
Structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and strength
