fire clay brick

Clay firebrick refers to the clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay firebrick based on local materials, cheap price, durable, but also fire, heat insulation, sound insulation, moisture absorption and other advantages, widely used in civil construction engineering, metallurgy and iron smelting industry.

Classification and Application

Clay firebrick is divided into clay firebrick for blast furnace, clay firebrick for hot blast furnace and large clay firebrick for glass kiln.

Clay firebrick for blast furnace

Clay firebrick for blast furnace is a kind of clay brick which is used to build the lining of blast furnace. Clay firebrick used in blast furnace is used in throat, body, cylinder, bottom of small blast furnace lining and large blast furnace body.

The clay firebrick for blast furnace requires high fire resistance at normal temperature and can resist the long-term operation wear of the charge. The volume is reduced under the long-term operation at high temperature, which is conducive to the integrity of the furnace lining, reducing the deposition of carbon in the pores, and avoiding the damage caused by the loose expansion of the firebrick in the process of use. Low melting point is less formed. Clay refractory brick for blast furnace has better performance than common clay brick.

Clay firebrick for hot blast stove

Clay bricks for hot blast furnaces are made of refractory clay and used for laying hot blast furnaces. Clay bricks for hot blast furnaces are used for hot blast furnaces, regenerators and partition walls. The clay bricks used in hot blast stove should have good thermal shock resistance, high softening temperature under load and small creep.

Large clay refractory bricks for glass kilns

Large clay firebrick for glass kiln is a clay firebrick with a single weight of no less than 50kg used for building glass kiln.Mainly used for the glass melting furnace working end tank bottom under the fused cast block .
