Selection of refractory fire brick for blast furnace 2

Sep. 11, 2017

Last episode we mainly described the selection of refractory fire brick for blast furnace. This episode we will introduce selection of refractory fire brick for medium blast furnace and ceramic burner.

Small and medium blast furnace(diameter<8m, blast temperature 1100〜1150℃):The top of the arch, the combustion chamber, the upper part, the heat storage room and the top of lattice brick should be built with blue crystal brick.The lower part of combustion chamber above the top of burner should be built with red pillar brick.The area with temperature lower than 1000℃(including lattice brick)should be built with fire clay brick.
Ceramic burner: The upper part is built with cordierite brick or red cylinder brick, the lower part is built with high density fire clay brick with low alkali metal content.
This episode we mainly describe selection of refractory fire brick for medium blast furnace and ceramic burner. Hope this can bring help to furnace builders and workers.
