Product Name | Silica brick |
Material | silicon oxide |
Function | The silica brick is mainly used for the partition wall of the
coking chamber and combustion chamber of the coke oven, the
regenerator and the slag chamber of the steel open furnace, the
soaking furnace, the refractory material of the glass melting
furnace and the firing kiln of ceramics, etc. Load-bearing parts.
It is also used for high temperature load-bearing parts of hot
blast stoves and acid open hearth furnace roof. |
