Description

technical field

[0001] The invention relates to a thermal energy technology, in particular to a heat radiation material and a refractory material using the heat radiation material. Background technique

[0002] It can be seen from the currently used industrial heating furnaces that in order to increase the heat obtained by the workpiece, the heat transfer in the furnace must be increased, so it is necessary to increase the emissivity of the furnace wall and increase the heat transfer area in the furnace. Most of the existing industrial heating furnace walls are refractory bricks, castables or refractory fibers, which have low emissivity, high energy consumption, and low heating efficiency.

[0003] The basic theory of heat transfer includes the following points:

[0004] A) The form of heat energy transfer: radiation, conduction, convection.

[0005] B) Stephen-Boltzmann law: E=Ξ΅ 0 C 0 (T / 100) 4 , the radiation intensity E is proportional to the fourth power of the temp...
