介绍了高温远红外涂料和红羹耐温精的物理性质的参数及其节能机理。由于加热炉体工作温度超过700℃后,热的传递以辐射传热为主,当炉体用红羹耐温精筑炉或修补窑、炉,或炉体的内表面喷涂高温远红外涂料后,使窑炉内衬(耐火砖)的黑度由0.4上升为0.98;这就使炉体内表面吸取的热量相应增加,由于炉体内热流的增加;缩短了加热时间,节约了能源;由于窑、炉涂上涂层后炉体的气密性好,涂层的导热系数小,使绝缘层内耐火砖的温度降低,相应的减小了炉体向外散热的能力,进一步提高了热的利用率。
The parameters of physical properties of high-temperature far-infrared coating and red hot-pressed temperature-resistant essence and their energy-saving mechanism are introduced. As the heating furnace operating temperature exceeds 700 ℃, the heat transfer to radiant heat transfer, when the furnace with red soup temperature fine precision furnace or repair the kiln, furnace, or the inner surface of the furnace after spraying high temperature far-infrared coating , So that the blackness of the lining of the kiln (refractory bricks) is increased from 0.4 to 0.98; thus, the amount of heat absorbed on the inner surface of the kiln is correspondingly increased, the heat flow in the furnace is increased, the heating time is shortened and the energy is saved; Furnace coated with a furnace after the gas tightness is good, the thermal conductivity of the coating is small, so that the insulation layer of firebrick temperature decreases, corresponding to reduce the ability of furnace body outward heat to further improve the utilization of heat rate.
