Fireproof material`s heat conductivity determining method for e.g. blast furnace lining, involves determining heat flow density and/or heat flow via furnace lining with sensor or from temperature difference of reference body in lining
The method involves determining heat flow density and/or the heat flow through a furnace lining (1) with a heat flow sensor (4) arranged in a furnace or from a temperature difference of a reference body arranged in the furnace lining. The temperature of a fireproof material is determined with a temperature measuring unit. The heat conductivity of the fireproof material in the area of the temperature measuring unit is determined from the heat flow through the furnace lining and/or the heat flow density and the measured values of the temperature measuring unit. Independent claims are also included for : (a) a method for determining changes of a heat conductivity of a fireproof material or damages in the material of a furnace (b) a measuring device for determining the heat conductivity or a separately determined parameter of a fireproof material.
