“对远红外烘芯炉的认识及实践”一文在《中国铸机》1986年第2期上刊登以后,不断地收到了全国各地读者的来信,接待了一批又一批的来访者。为此,针对咨询者提出的几个较为集中的问题,再谈一谈远红外烘芯炉。一、远红外烘芯炉的节电原理砂芯的干燥,一方面是水分等的挥发,另一方面是低分子化合物经过氧化聚合反应转变成高分子化合物的过程。其中水分的挥发速度决定于水分从砂芯表面蒸发的速度和水分由内 After the publication of “China Casting Machine”, Issue 2, 1986, it continuously received letters from readers all over the country and received batch after batch of visitors. To this end, the consultant for several more focused on the issue, talk about far-infrared drying oven. First, the far-infrared drying furnace power-saving principle Drying the sand core, on the one hand the volatility of water and the like, on the other hand, is the process by which the low-molecular-weight compounds are converted to the high-molecular-weight compounds by the oxidative polymerization reaction. One of the water evaporation rate depends on the speed of moisture evaporation from the sand core surface and moisture from the inside
