Mullite brick is a refractory brick with mullite as the main crystal phase. It has high softening temperature under load, low creep rate at high temperature, good thermal shock resistance, and strong acid slag erosion resistance. Classification, mainly in the following aspects:
Mullite Brick Application
_06
Mullite bricks are divided into light mullite bricks and heavy mullite bricks according to different bulk densities. The main applications of light mullite bricks are: metallurgy, petrochemical, building materials, ceramics and other industries Thermal layer, such as heating furnace, soaking furnace, heat treatment furnace, tunnel kiln, roller kiln, shuttle kiln, etc.
Mullite bricks have a wide range of applications, but the choice of refractory bricks for industrial kilns should be the first to meet the needs of the kiln, and the second is to consider the economic benefits, and comprehensively consider the selection of mullite bricks for the kiln.
Mullite ceiling tile product application:
Mullite ceiling bricks have high whiteness, uniform arrangement of pores, high flexural and compressive strength, and can be directly used for lining ceilings of various industrial kilns.
Scope of application of mullite ceiling tiles:
It is used in various industrial kilns, such as bell furnaces, heating furnaces, cracking furnaces, heat treatment furnaces, shuttle kilns, tunnel kilns, roller kilns, enamel kilns, ceramic kilns for ceilings and walls, and thermal insulation lining materials.
Large-scale roller kilns in the building materials industry, large-scale tunnel kilns, shuttle kilns, push-plate kilns in the daily ceramic industry, large-scale red brick production line tunnel kilns, refractory tunnel kilns, shuttle kilns, etc.
Mullite polylight bricks refer to light refractory products containing Al2o330%-46%. The main principle is clay clinker or light clinker and plastic clay. It is usually produced by the combustible method, and can also be produced by chemical method or foam method. form a porous structure.
The bulk density of the commonly used mullite polylight brick is 0.75-1.20g/cm3, the compressive strength is 2.0-5.9MPa, and the thermal conductivity is 0.221-0.442W/(m.K) (1350℃).
Mullite polylight brick has a wide range of uses, mainly used in various industrial kilns for thermal insulation layer materials without contact with molten material and without the effect of erosive gas. The operating temperature is 1200-1400 °C.
Mainly used in thermal boilers, glass furnaces, cement furnaces, fertilizer gas furnaces, blast furnaces, hot blast furnaces, coking furnaces, electric furnaces, casting and steel casting bricks, etc.
Mullite polylight bricks can be used as hot surface refractories or other refractory materials to support thermal insulation in melting furnaces, ignition kilns, flues, refining units, heating units, regeneration units, gas furnaces and pipes, soaking furnaces , annealing furnaces, reaction chambers and other industrial thermal equipment.
