一、前言目前国内电焊条行业用于焊条药皮干燥,烘烤的能源浪费还相当普遍。上海东亚电焊条厂国内首创建造了以远红外煤气辐射管为加热源的电焊条自动烘道,投产三年来的生产实践证明,节能效果非常显著。使用远红外煤气辐射管的自动烘 I. Preface At present, the welding electrode industry in China is used for electrode coating drying and the energy waste of baking is quite common. Shanghai East Asia welding electrode factory in China to create the first to the far-infrared gas radiant tube for the heat source of the electrode automatically bake, put into production three years of production practice has proved that energy-saving effect is very significant. Automatic baking with far-infrared gas radiant tubes
