现在有许多厂家为了产品延伸,需要将高炉或冲天炉铁水作升温处理,常采用无芯感应电炉作为升温设备。由于我国无芯炉系列以熔化炉为主,其特点是:功率大,炉身细高,线圈高度也高。这些特点对熔化金属用是合适的,电效率高,启熔时有效加热层总面积大,有利于熔化。但若作为铁水升温用这三点都是不合适的。一、功率和容量的矛盾
Now there are many manufacturers in order to extend the product, the need for blast furnace or cupola hot metal for heating treatment, often using coreless induction furnace as a heating device. As China’s coreless furnace melting furnace-based series, which is characterized by: power, tall furnace, coil height is also high. These characteristics of the metal is suitable for melting, high electrical efficiency, starting the heating effective heating layer when the total area is large, is conducive to melting. However, if the hot metal used for these three points are not suitable. First, the contradiction between power and capacity
