According to the principle of thermal engineering, products are heated and sintered in high-temperature kilns, mainly relying on radiation heat transfer and heat transfer to complete the heat transfer of heat sources and heated products. The furnace body is coated with high temperature infrared thermal reflection coating and high temperature infrared radiation coating, which makes the furnace burn more fully burn rate higher, improves the furnace furnace temperature, improves the heat energy utilization rate is better, and keeps the furnace temperature for a long time. In view of the above-mentioned difficulties, after thousands of tests and the use of specific furnace body proved that the researchers spontaneously developed high-temperature thermal reflection coating and high-temperature far-infrared radiation coating, high-temperature thermal reflection coating brushing on the surface of high-temperature materials can effectively achieve infrared isolation, weakening the conduction of high-temperature thermal electromagnetic waves to reduce heat transmission, high heat reflectivity, thereby effectively reducing the heat absorption of objects per unit of time, reduce the surface temperature of the object. High temperature-resistant far-infrared radiation coating high temperature, strong radiation rate, corrosion resistance and high wear resistance, through the coating infrared radiation, improve the heat exchange conditions in the furnace, improve the combustion temperature and uniformity in the furnace, so that the fuel combustion more fully, to achieve heating efficiency, improve furnace temperature, energy saving and protection of the furnace wall extended the lining of the furnace lining time.
the energy saving effect of applying high temperature thermal reflection coating and high temperature far infrared radiation coating on the inside of high temperature furnace furnace is higher than that of a single far infrared coating coating. The furnace interior is coated with transition coating according to different insulation materials, and then the high temperature thermal reflection coating and the high temperature far infrared radiation coating are applied separately.
when the operating temperature of the furnace is 700 degrees C, the heat transfer is mainly radiation (more than 90%,) and the energy saving effect is better with high temperature and energy-saving coatings. The substrate is first coated with high temperature thermal reflection coating, and the high temperature far infrared radiation coating is applied. When the temperature of the furnace furnace is as high as 700 degrees C or more, the high temperature far infrared radiation coating line absorbs heat, high infrared radiation, the bottom layer of high temperature thermal reflection coating as a high temperature far infrared radiation coating thermal shielding reflective coating, to avoid high temperature far infrared radiation coating absorbed by the high temperature heat transfer to the furnace wall insulation material, reduce heat loss, increase the amount of infrared radiation. The special treatment of high temperature thermal reflection coating material, the reflection, shielding and radiation rate of infrared electromagnetic waves at different temperatures are high, which effectively reduces the thermal absorption rate of the material per unit of time, reduces the amount of heat per unit of time propagation, increases the reflectivity, shielding rate and radiation rate of infrared light, and increases the thermal resistance value of the material. High temperature-resistant far-infrared radiation coating is a high temperature (temperature can reach 1800 degrees C), strong radiation rate (0.95), corrosion resistance and high wear resistance of special features energy-saving coating, through the coating infrared radiation, improve the heat exchange in the furnace, improve the temperature field strength and uniformity in the furnace, make the fuel combustion more full, achieve increased thermal efficiency, greatly improve the thermal efficiency of refracing materials, reduce energy consumption, save energy and extend the life of the furnace. High temperature-resistant far-infrared radiation coating contains strong radiation materials at high temperature radiation penetration of very strong far-infrared waves, so that the heated object molecules absorb waves to produce energy stage jump, absorb energy uniform heat, reduce heating time, fully save energy, high-temperature thermal reflection coating and near-infrared radiation coating composite brush energy saving is more obvious.
