Embodiment 1

[0098] The furnace heat radiation element 21 can be arranged on the refractory material in the furnace, such as refractory bricks, and the shape of the furnace heat radiation element can be eight-sided cone, six-sided cone, cone, cone or cylinder. Alternatively, the structure of the furnace heat radiation element adopts the form of a cavity, that is, an octagonal cone, a hexagonal cone, a cone or a cylindrical cavity is arranged inside the body of the refractory brick.

[0099] like figure 2 and 3 As shown, the furnace heat radiation element 21 adopts a hollow hexagonal pyramid structure, and the furnace heat radiation element 21 is arranged on the upper plane of the refractory brick 20 . The furnace heat radiation element 21 is surrounded by six side walls, and a bottom surface may also be provided at the bottom of the furnace heat radiation element 21 . The furnace heat radiation element 11 has an inner wall and an outer wall, which can effectively increase the heat trans...

Abstract

The invention discloses a fire-resisting material using a thermal-radiating material, comprising a fire-resisting material body, wherein a furnace thermal-radiating element is arranged on the fire-resisting material body, and the thermal-radiating material is coated on the outer surfaces of the fire-resisting material body and the furnace thermal-radiating element. The invention also discloses a thermal-radiating material. Aiming at the defects of various traditional industrial heating furnaces, the thermal-radiating material is sprayed and arranged on the inner wall of a furnace to reduce the thermal loss of an industrial heating stove, thereby increasing heat efficiency and achievingthe purposes of saving energy and reducing emission.

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=ε 0 C 0 (T / 100) 4 , the radiation intensity E is proportional to the fourth power of the temp...
