Abstract

The invention discloses a blackbody material and an energy-saving radiation cup made of such blackbody material, belonging to the technical field of energy-saving material. The blackbody material is composed of the following constituents according to percentage by weight: 95% of silicon carbide, 0.5% of iron trioxide, 0.5% of manganese dioxide and 4% of aluminum oxide. The energy-saving radiation cup comprises a cup body and a cup bottom, wherein the cup body is in the shape of a straight cylinder, the middle of the cup body is a hollow cavity, the part of the hollow cavity close to the cup bottom is spherical, and the section of the outlet of the hollow cavity is trapezoidal; an arc groove is arranged on the cup bottom plane. The blackbody material provided by the invention has the advantages of greatly reducing heating-up time of hearth and improving the uniformity of hearth temperature, improving the capacity of industrial kilns and industrial boilers, and saving fuel, wherein the energy saving rate can be 7%-20%.

Description

technical field [0001] The invention belongs to the technical field of energy-saving materials, and in particular relates to a blackbody material with high blackness coefficient, good thermal conductivity, high absorption and high radiation effect in the far-infrared band, and an energy-saving radiation cup made of the blackbody material. Background technique [0002] my country's industrial kilns and industrial boilers are the main body of energy consumption. However, industrial kilns and industrial boilers generally have low thermal efficiency and relatively large energy waste. In view of the low effective utilization rate of energy and relatively large energy waste in industrial kilns and industrial boilers, the main energy-saving measures generally adopted in China are: (1) Use light-weight thermal insulation materials with good thermal insulation effects as much as possible; 2) Far-infrared energy-saving paint spraying technology is adopted; (3) waste heat recovery and...
