近年,日本现代工业利用电气加热有所增加,在今后,使用电气作为加热源的趋势也不会有变化. 现就介质加热的利用简要的加以说明介质加热是把被加热物放置在高周率电场里,直接由那被加热的内部产生热量的加热方式.与通常在被加热的近旁燃烧、通热风或电热丝加热等直接传导热有显著不同的 In recent years, Japan’s modern industry has increased its use of electric heating. In the future, there will be no change in the use of electricity as a heating source. Now, the use of medium heating is briefly described. The medium heating is to place the object to be heated at a high rate. In the electric field, the heating method that generates heat directly from the heated interior is significantly different from the direct conduction heat that is usually burned nearby, such as burning, hot air or heating wire heating.
