20211014 A blast furnace hearth is subject to severe chemical attack and thermodynamic strain in every single processing run throughout its service life This is where coke iron ore and limestone are melted by pressurized coustion air at temperatures exceeding 1000 °C The molten iron is then tapped and separated into slag and pig iron a process that is increasingly
Checker brick is a heat transfer medium It is applied in the regenerator of blast furnace hot blast stove usually ordered arrangement in the regenerator and it plays a role of heat storage during the burning period During the “air supply period” the cold air is heated into hot air through convection heat exchange and radiant heat exchange
199681 @articleosti_367896 title = New concepts and designs for blast furnace linings and cooling systems author = Carmichael I F abstractNote = In the 1960`s concurrent with major technological developments in blast furnace operation cooling became increasingly important in extending furnace campaign life Cooling systems developed from simple shower spray and
2020610 Blast furnace is shaft furnace which burns coke by hot air to reduce iron ore to metallic iron High density high alumina brick is used for furnace throat usually The furnace body and the central temperature is only 400800℃ no slag formation Advanced refractories such as high alumina brick and silica wire brick are used for this this area
