CEIC Database Expansion: World Steel Crude Steel Production and Continuously-Cast Steel Output

January 17, 2014 - CEIC Data NewsAlert: Sector Database Expansion THEME To further enrich the CEIC Database, the CEIC Sector Database has been enhanced with the addition of Crude Steel Production by Process and Continuously-Cast Steel Output statistics in the Iron and Steel Sector. The newly added datasets of crude steel production provide statistics relating to the steel production processes (Electric Furnaces, Oxygen Blown Converters and Open Hearth Furnaces) and their related output ratios. Statistics for continuously-cast steel production are also included in this expansion. These datasets provide a general overview of the main trends in the field of steel plant technology. The datasets are directly sourced from the World Steel Association (worldsteel). Both members and non-members supply information to worldsteel for the compilation of its publications. National steel associations’ information has been used where possible. HIGHLIGHTS Since the 1970s, the open hearth furnace (OHF) production as a share of total steel production has dropped gradually from more than 30% to just 1% in recent years. With the advent of the oxygen steel making technology, which could produce steel in a shorter time, OHF is expected to be phased out completely in the near future. It is still in use in a few countries, mainly Russia and Ukraine, accounting for 9.6% and 26% of their countries’ total crude steel output in 2012. The Oxygen Blown Converter (OBC) process, where pure oxygen is “blown” into the basic oxygen furnace vessel, which converts the raw materials - scrap iron and steel, and carbon-rich molten pig iron - into the finished steel product, is a self-sustaining energy process. Thus, OBC remains the world’s dominant steel-making method, having seen increasing popularity over the past forty years. As of 2012, it accounted for 69.6% of global crude steel production. Despite the increasing use of OBC globally, the US and India are among the two key players that have seen the decreasing use of OBC in favour of the Electric Furnace (EF) process. The latter accounted for 59.1% and 67.1% of total crude steel production during 2012 in the US and India respectively. The EF process has contributed to about one-third of the world’s total crude steel production in the past twenty years. It refers to heating charged materials by means of a high-power electric arc. Its major advantages are its ability to accept scrap, directly-reduced iron and molten hot metal in various proportions, and the flexibility it allows steel mill operators to vary production according to demand. Also, due to its lower capital cost, some of the minor crude steel producers (e.g. Croatia, Cuba, Mongolia, Nigeria and Uruguay) are fully dependent on this process. Continuous casting is the process where molten steel is solidified into a "semi-finished" billet, bloom or slab for subsequent rolling in the finishing mills. Continuous casting is widely adopted by steel makers, with the market share of the continuous-cast process rising continuously, to more than 90% in the past decade. The advantages of continuous casting over ingot casting are better yield and quality, as well as higher productivity given the extent of automation and cost efficiency; unlike ingot casting which requires specialized mills.
