▲英国M.H.Detrick公司研制出的高里度耐火涂料,可以改善炉墙、炉顶、炉底内壁的特性,涂层的高里度可提高壁温,从而显著的节约燃料。由于炉墙再辐射给工件热量增加,一台使用陶瓷纤维贴面的热处理炉,用高黑度涂料的贴面进一步节能25％。节能的原因之一还由于涂层很细,使纤维耐火材料表面孔隙减少,有利于将炉墙热量辐射给工件。使用涂层的退火热处理炉的退火
▲ British M.H.Detrick company developed high temperature refractory coating, can improve the furnace wall, roof, bottom wall characteristics, the coating of high degree can increase the wall temperature, which significantly save fuel. As the furnace wall re-radiation to increase the heat of the workpiece, a ceramic fiber veneer heat treatment furnace, with a black paint coating further saving energy by 25%. One of the reasons for energy saving is also due to the coating is very thin, so that reducing the surface porosity of the fiber refractory, is conducive to the furnace wall heat radiation to the workpiece.
