Title: Top even pressure control of large blast furnace in Taiyuan Iron and Steel Co
Abstract:In order to improve smelting coefficient of blast furnace,produce more molten iron and decrease energy consumption,enterprise usually adopts furnace top high pressure operation.In large blast furnace,...In order to improve smelting coefficient of blast furnace,produce more molten iron and decrease energy consumption,enterprise usually adopts furnace top high pressure operation.In large blast furnace,the pressure difference between furnace top and material pot is larger than 0.015 MPa after the first even pressure control by use of gas because of higher furnace top pressure.Hence,charging operation should be carried out after the second even pressure control by use of nitrogen.The principle of furnace top even pressure control for 1 650 m~3 large blast furnace and 4 350 m~3 super huge blast furnace of Taiyuan Iron and Steel Co is introduced.Read More
