Last issue we mainly introduced the mullite material. This issue we will continue to introduce 6 characteristics of mullite lightweight insulating fire brick.
Due to its chemical structure, mullite lightweight insulating fire brick has below 6 characteristics.
1 Low thermal conductivity. Very good thermal insulation performance.
2 Low heat capacity. Due to low thermal conductivity, mullite lightweight insulating fire brick accumulate little heat energy, and the energy saving performance is prominent in intermittent operation
3 Low impurity content. Very low oxide content such as iron and alkali metal, therefore, it has high refractoriness. High aluminum content enables it to maintain good performance under reducing atmosphere.
4 High compression strength under high temperature.
5 Accurate appearance dimension speeds up the masonry, reduces the amount of refractory mud, ensures the strength and stability of the masonry, and extends the life of the lining.
6 Can be processed into special shapes. Therefore reduces the number of bricks required and seams in masonry.
This issue we mainly introduced 6 characteristics of mullite lightweight insulating fire brick. Hope this can bring help to furnace builders. Next issue we will continue to introduce the production method of mullite insulating fire brick. Please stay tuned.
