近年来,可控硅中频变频电源的掘起,使感应加热技术更加广泛地应用到各个工业领域。采用步进式的加热炉进行钢的圆柱件透热以完成相应的热加工(如锻造,轧制和挤压等)是中频感应加热的主要应用领域之一。目前,加热炉多为用户自行设计配制,可控硅电源对负载的适应能力又比较差,所以,较准确地进行感应器的设计计算就成为一个很突出的问题。现行之计算方法,据一些单位反映,误差较大,达20％左右。本文介绍一种修正后的计算方法,供兄弟单位参考使用,并祈得到修正和交流。
In recent years, the tripping of mid-frequency SCR power frequency induction heating technology so that more widely used in various industrial fields. One of the major applications of IF induction heating is the use of a step-by-step reheating furnace to conduct heat through the cylindrical members of the steel to perform the corresponding hot workings (forging, rolling and extrusion, etc.). At present, most of the heating furnaces are designed by the users themselves, and the adaptability of the SCRs to the load is relatively poor. Therefore, the accurate calculation and calculation of the inductor becomes a prominent problem. The current calculation method, according to some units, the error is larger, reaching about 20%. This article describes a revised calculation method for reference by brothers and institutions, and pray for amendment and exchange.
