blast furnace ironmaking
Blast furnaces are gigantic steel furnaces in which iron ore, limestone, and coke are heated to temperatures in excess of 1750 degrees Celsius. The carbon in the coke and the heat within the furnace combine with the iron oxide to form a mixture of iron, carbon monoxide, and slag, and this mixture ......

Blast Furnace Batch Calculation
Coke blending is the process of automatically calculating the correct proportions of coking coal for the blast furnace. The process requires a combination of both theoretical and practical knowledge in order to produce a coking mixture of coals and raw materials that maximizes efficiency and minim......
blast furnace differential pressure
Blast furnace pressure difference
Blast furnace pressure difference is the difference between the pressure inside the furnace and the pressure outside. This pressure difference helps the furnace produce a higher level of blast air. The pressure difference is also important for ensuring the optimal......

Quantity and installation position of gas supply components at the bottom of re-blowing converter
Reinstalling the Gas Supply Components at the Bottom of a Blast Furnace
The process of restoring the blast furnace to peak efficiency begins with a proper reinstallation of the gas supply components located at the bottom of the furnace. This paper will focus on providing a description of the tools......
Requirements for bottom gas supply components and structural characteristics of gas supply components in re-blown converters
In a converter furnace, the bottom supplying elements play a crucial role in the smelting process, providing a regulated supply of gases and other process material to the furnace as it is stepped up in temperature. This regulated supply ensures that any slag created in the process is eliminated fr......
