Types and brief introduction of functional refractory
insulation materials
Functional fire-resistant insulation materials, including high-performance fire
resistant insulation materials, high radiation rate saving coatings, high thermal
conductivity and high conductivity refractory preservation materials, high
performance rapid thermal insulation materials,etc.
High emissivity energy-saving coating using its radiation range of the heat radiation
within the high emissivity (or high absorption rate),after spraying inside of the furnace,
can effectively improve the furnace flame and flue gas rate in the utilization of radiation
energy, thereby reducing the gas released Temperature, reduce the exhaust heat loss.
High thermal conductivity of refractory insulation materials is used for high temperature
flue gas heat exchange and waste heat recovery. When the gas temperature is about
1300 ℃, the use of thermal efficiency of 60% of the ceramic heat exchanger, can save
about 48% of the fuel, while the use of metal heat exchanger can save only 24% of the
fuel. High thermal conductivity is the minimum requirement for ceramic heat exchanger
materials, silicon carbide material has good mechanical properties and high thermal
conductivity, is widely used in ceramic heat exchanger materials.
High-performance thermal insulation materials include refractory ceramic fiber
products, ultra-fine porous light brick, light unshaped refractory insulation materials,
such materials have very low thermal conductivity, masonry furnace wall when using
such materials Can significantly reduce the heat dissipation and heat loss of the furnace,
which has a significant energy saving effect.
High temperature air fuel technology developed in recent years is a new combustion
and limit waste heat recovery technology, the technology of using the regenerator will
fully recover the residual heat in the flue gas, and the combustion air is heated to
800~1000 DEG C, and exhaust temperature can be reduced to 130~150 DEG C.
Insulation material is the key material of regenerator regenerator, it is the media of
heat exchange in the regenerator, it will heat the furnace flue gas absorbed over the
storage, and then use the stored heat to air or fuel heating, so that not only improves
the preheating temperature of air and fuel, reduce exhaust emissions temperature,
energy saving at the same time, also greatly reduced CO2 and NOx emissions, beneficial
to environmental protection
High conductive refractory thermal insulation material is widely used in the DC arc furnace.
The bottom electrode of DC arc furnace has several forms, like ABB type bottom electrode
is formed by thermal conductive refractories, it requires MgO and C conductive refractory
material thermal insulation material resistivity as small as possible, while the bottom
electrode resistance higher than several other made of metal, but its good reliability,
convenient maintenance,high life expectancy.
