众所周知,盐浴炉的热损失主要是盐浴表面的辐射。因此,减少热辐射是盐浴炉节能的重要途径。为了降低热辐射,有的单位在盐浴表面覆盖一层木炭、石墨等漂浮微粒。但由于木炭和石墨消耗很快,加上在高温时产生烟雾污染,使其应用受到限制。为了消除上述微粒的弊端,我们选用了耐火度高、热稳定性好、导热系数低的煅烧高铝石(粒度5～10mm)作了覆盖试验。覆盖厚度为2cm时测
As we all know, salt bath furnace heat loss is mainly salt bath surface radiation. Therefore, reducing heat radiation is an important way to save energy in salt bath furnaces. In order to reduce heat radiation, some units in the salt bath surface covered with a layer of charcoal, graphite and other floating particles. However, due to the rapid consumption of charcoal and graphite, coupled with smog pollution at high temperatures, its application is limited. In order to eliminate the disadvantages of the above particles, we selected the calcined aluminaite (particle size 5 ~ 10mm) with high refractoriness, good thermal stability and low thermal conductivity. Cover the thickness of 2cm measured
