Hot blast stove is the blast furnace heating air equipment, is one of the main supporting equipment for ironmaking blast furnace, generally a blast furnace with 3 to 4 hot blast stoves, the role of the hot blast stove ?is to continuously provide the blast furnace with more than 1000 ℃ of high temperature hot air, advanced hot blast stove wind temperature can reach 1300 ℃.
According to the stove type, Hot blast stove has top-combustion, internal combustion type, external combustion type, etc. It usually consists of heat storage room, combustion room, burner, hot air duct, etc.. According to the application area, the refractory material configuration as follows:
1, the lower part of the heat storage chamber: clay brick, heat-resistant concrete
2, the middle of the heat storage chamber: low creep clay bricks, high alumina bricks, low creep high alumina bricks
3, the upper part of the heat storage chamber: low creep high alumina bricks, silicon bricks
4, combustion chamber: low creep high alumina bricks, silicon bricks
5, burner: clay bricks, cordierite - mullite bricks
6, hot air duct: low creep high alumina bricks
