direct reduced sponge

Welcome to SBQ Steels Ltd

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of Hydrogen (H2) and Carbon Monoxide (CO) which acts as reducing agent.

Steel and Direct Reduced Iron (sponge Iron) Industry

Direct Reduced Iron, with its sponge – like structure, is chemically active and easily oxidized. The author has developed an efficient process for the treatment of sponge iron, known as the Waxing Process, which makes the sponge iron resistant to both oxidation and corrosion and no heat generated which causes fire.

Direct Reduced Iron

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces.
