Clay bricks for coke oven

Refractory bricks fire clay bricks brick for coke oven

Composition and characteristics of clay brick

The corresponding refractoriness is not less than 1700℃, 1670℃ and 1610℃;The softening temperature under load was between 1250 ℃ and 1450℃.Good thermal stability.It is generally used in the drying zone, pre-heating zone, decomposition zone and cooling machine of rotary kiln.In recent years, many countries have developed special clay bricks in order to improve the fire resistance temperature while maintaining alkali resistance.

What physical and chemical index does clay brick have

Clay brick is made of clay clinker as aggregate and refractory clay as binder.Its Al2O3 content is 30%~48%, suitable for heat exchange position, chain belt, decomposition zone, cooling zone, smoke chamber, grate cooler, etc., the brick wear-resisting performance is good, thermal conductivity is small, the price is cheap, only other brick price 1/4 ~ 1/2, but the fireproof degree and strength are lower.
