| Blast furnace steel production of the company’s core sectors(smelting, energy consumption, cost body), the blast furnace longevity has an important impact on the survival and development of iron and steel enterprises and competitiveness.Angang Steel Company Limited in ironworks 1 # blast furnace since April 8,2003 furnace furnace production to January 18, 2011 off-air furnace hearth occur during cylinder filling burn accident lasted seven years and nine months. Generation furnace life far below the design life.In this paper, theoretical analysis and experimental research discusses two aspects One reason new blast furnace hearth erosion, stability and longevity of the proposed feasibility study according to the program, to determine the blast furnace in the production process by which the technical parameters of blast furnace to ensure fair and orderly production.Blast lifetime is a systems engineering, is a comprehensive index, after the design, construction and other sectors completed, blast furnace daily operations,management has become a key factor in the impact of the blast furnace life.Longevity a new blast furnace ironmaking blast Angang Steel Plant to strengthen the management and through continuous exploration and gradually formed a stable high yield as the goal, on the basis of stability along the line, the standardized operation to ensure the device is working properly, to achieve energy saving, extend the life of the blast furnace, and to combine, always through the blast furnace production. |
