Lightweight clay insulation brick

(1) Lightweight clay insulation brick refers to light refractory products containing Al2o330%-46%. The main principle is clay clinker or light clinker and plastic clay. It is usually produced by combustible method or chemical method or The foam method forms a porous structure. The commonly used lightweight clay bricks have a bulk density of 0.75-1.20g/cm3 and a compressive strength of 2.0-5.9MPa, and a thermal conductivity of 0.221-0.442W/(m.K) (1350°C).

(2) Lightweight clay thermal insulation bricks are widely used in various industrial furnaces without contact with molten material and non-erosion gas. The temperature is 900-1000 ° C, with low capacity and high porosity. Small heat conduction, high temperature resistance, good thermal insulation performance, etc., can reduce the volume of thermal equipment and reduce its weight, shorten the heating time, ensure uniform furnace temperature, reduce heat loss, save energy, save material and extend service life, improve work effectiveness.

(3) Lightweight clay insulation bricks are mainly used in thermal boilers, glass kiln furnaces, cement kiln furnaces, chemical fertilizer gasifiers, blast furnaces, hot blast stoves, coking furnaces, electric furnaces, casting and steel pouring bricks.

(4) Lightweight clay insulation bricks can be used as thermal surface refractories or other refractory materials to support insulation layers for melting furnaces, ignition kiln, flue, refining equipment, heating equipment, regeneration equipment, gas furnaces and pipelines, all Other industrial thermal settings for hot furnaces, annealing furnaces, and reaction chambers.
