Analysis of Thermal Energy Saving Effect of Fusion Aluminum High Temperature Far Infrared Coatings

[China Aluminum] High-temperature air combustion in the aluminum melting process has changed the traditional combustion method, using the flue gas recirculation method or direct injection combustion of the fuel furnace, mainly as the combustion of the combustion air through the ceramic honeycomb is preheated to 1000 Above °C, it is sprayed into the furnace at an appropriate speed, mixed with the combustion products in the furnace under the action of high-speed airflow suction and stirring. 21% of the oxygen in the air is diluted at low oxygen concentration (5% to 6.5% for zui) Combustion in the fluid and combustion under high temperature air conditions can achieve low air-coefficient combustion and reduce the oxidation loss of aluminum. ZS-1061 high temperature resistant far-infrared radiation coating on the high temperature equipment of melting aluminum, the emissivity reaches <e_0.96, energy-saving coating of wall thermal radiation, the blackness of the furnace wall is close to absolute blackbody, so the radiating ability of the lining to the heated object is greatly increased? The speed of the heated object is significantly increased, and the natural fuel saving rate is also correspondingly increased. However, the radiation of the furnace wall increases, and the wall of the furnace 囟 囟 囟 龈撸 needle 囟 蚨 谙蛲獯 谙蛲獯 谙蛲獯 谙蛲獯 龋 龋 龋 鹗 鹗 龃舐 龃舐 龃舐 龃舐 龃舐被露鹊、淮、浯、锹、谖露、鹊露鹊焦所以? Therefore, the heated workpiece or other material is still less than the furnace wall. The heat is much larger, so the brushed aluminum ZS-1 heat-resistant thermal insulation coating on the furnace wall can still achieve energy-saving purposes.

1. Aluminum alloy ZS-1061 high temperature resistant far-infrared radiation coating has the characteristics of high emissivity, long service life, small thermal conductivity, good airtightness and high refractoriness;

2. The infrared heating method of the heat-resistant far-infrared radiation coating ZS-1061 of molten aluminum has uniform heating and high thermal efficiency;

3, aluminum alloy ZS-1061 high temperature resistant far-infrared radiation coating adhesion is not easy to fall off, corrosion resistance;

4, Al-ZS-1061 heat-resistant far infrared radiation coating construction is simple and rapid, energy saving and stable;

5, aluminum alloy ZS-1061 high temperature far infrared radiation coating to improve fuel combustion efficiency, reduce emissions;

Al-alloyed ZS-1061 high temperature resistant far-infrared radiation paint is brushed or rolled on the refractory surface of various high-temperature kilns, or on the surface of water-cooled wall tubes of steam boilers. It is tightly integrated with the inner wall of the furnace to form a solid surface coating. The layer isolates the refractory surface from direct contact with the combustion air stream. Different energy furnaces have different energy-saving effects. The higher the temperature is, the better the energy-saving effect is, and the energy-saving effect of the resistance furnace is better. This reduces the maintenance and repair workload and cost of the furnace and reduces the labor intensity of the employees. Aluminum ZS-1061 high temperature far infrared radiation coating effect: 1. Improve the efficiency of the use of the furnace, shorten the heating time, increase production, improve the heating efficiency of 5 - 15%. 2. Fuel consumption energy-saving rate of up to 5 - 25%. 3. Increase the temperature in the furnace by 20 to 100 degrees, reduce the surface temperature of the furnace by 5 to 45 degrees, and reduce the temperature of the exhaust gas by 10 to 45 degrees. 4. Prolong the service life of the furnace by more than double, and reduce the content of flue gas combustibles. above 50. 5. Avoid the scouring and erosion of the kiln wall by airflow, and play the role of protecting the furnace body and extending the furnace age.
