Product Details

Fire clay brick is made in china with china national standard that are widely used in ceramic kiln and cement kilns.

Fire clay brick have good thermal shock resistance and its fluctuation range is big that is generally more than 10 times(1100 in cold water).

Fire clay brick belongs to weak acid refractory products, which acid performance is enhancing along with the increase of SiO2 content.

It has definite erosion resistance to acid slag but weak resistance to alkaline slag. Therefore fire clay brick is suitable for the lining of the furnace with acid slag.
