US-based consulting firm World Steel Dynamics,[link widoczny dla zalogowanych], said that in 2004 a quarter of global steel shortage appears likely to 85%. 2002 steel prices have been on the rise,[link widoczny dla zalogowanych], the industry profit prospects for the future, the world's steel Power company said more than 2002, the company's global survey of 35 large steel manufacturers pre-tax income in 2003 will increase by 10%. In 2003 the world's major steel company's share price has increased by 40% compared to 2000 increased by 150% at low tide. iron and steel industry the recent spate of merger activity also contributed to the development of these trends, because the large steel companies merged to larger, more powerful and thus have pricing power, 18 months ago, Europe three steel companies merged to form the Luxembourg-based steel maker Arcelor, the world's largest steel group, then pour in the steel industry merger activity. In addition, China's sharp increase in demand for steel is also a factor, the International Iron and Steel Association predicts that in 2004, Steel consumption in China will account for 31% of the world's total,[link widoczny dla zalogowanych], compared to .2001, its total steel consumption in the world, compared to only 22%. satellite feed Nippon Steel Kimitsu No. 4 blast furnace plant re-ignition, according to Japanese trade open May 9, 2003 the information provided, after 88 days of maintenance, the Japanese Nippon Steel Kimitsu (Kimitsu) No. 4 blast furnace plant in the May 8 re-ignition. After the service, blast furnace No. 4 content from 5151m3 to 5555m. Pig iron production capacity from 12170t / d increased to 12900t / d. Nippon Steel Kimitsu No. 4 blast furnace plant put into operation in 1975 and 1986, discontinued in 1988, resumed production in February 2003 cut-off again . Xu group feed
