针对现有加热气体感应电炉存在的问题,著者提出一种新型炉体结构,特点是具有喷流换热装置,外筒开缝使之不成闭合回路,附加磁轭。在实验室中进行的小型实验证明,所采取的改进措施都是行之有效的,新型炉的结构可靠,体积小,电热效率高,功率因数也高。根据电工原理,提出了设计计算关系式,应用这些关系式所得的计算值,和实验测定值基本符合。 In response to the existing problems of heated gas induction furnace, the authors propose a new type of furnace body structure featuring a jet heat exchange device with a slit in the outer cylinder that does not form a closed loop with additional yokes. The small experiments conducted in the laboratory proved that the improvement measures taken are all effective. The new furnace has the advantages of reliable structure, small size, high electric heating efficiency and high power factor. According to the principle of electrotechnics, the calculation formulas of design and calculation are put forward, and the calculated values ​​obtained by applying these relations are in good agreement with the experimental values.
