The difference between the ceramic fiber blanket and rock cotton blanket
Ceramic fiber lining: low thermal conductivity of ceramic fiber lining in the average temperature of 400 degrees, the thermal conductivity is less than 0.1w/mk, the average 600 degrees less than 0.l5 w/mk, average 1000 degrees less than 0.25w/mk, about l/8 as a lightweight clay brick, lightweight refractory lining l/10, adiabatic effect.The construction of ceramic fiber lining is simple: no expansion joints are needed during construction, and the construction personnel can be started after the basic training. The technical factors of construction have little influence on the insulation effect of the lining.
The heat capacity (heat storage capacity) of ceramic fiber lining is low: the heat capacity of ceramic fiber is only about l/10 of light heat resistant lining and light castable lining, and the heat capacity of lining material is proportional to the weight of lining. Low heat capacity means the furnace in the reciprocating operation absorb less heat and heating speed, greatly reducing the operational control of the temperature in energy consumption, especially for heating furnace and furnace, furnace shutdown has obvious energy saving effect.
Refractory ceramic fiber material is a lightweight and efficient thermal insulation material. It has the following advantages over traditional heat insulation materials:Ceramic fiber as lining, low volume density: ceramic fiber lining than light heat insulation brick lining light more than 75%, lighter than light castable lining light 90% to 95%. If using fiber lining, it can greatly reduce the steel structure load and prolong the service life of the furnace.
