1．现代铸铁工厂中有芯感应电炉的地位作者J.M.Cartlidge作者简述了有芯感应电炉发展应用情况及当前在铸铁熔炼方面所占地位.比较了有芯和无芯两种感应电炉的相同与不同之处之后,提出,有芯感应电炉具有电效率高及热损失小的特点,再加上具有停工损失小和能保持与炉内金属液面高度无关的稳定电功率水平,使得有芯感应电炉成为一种理想的保温炉或双联用炉,并举出几个实例加以说明. 1. The Status of Cored Induction Furnaces in Modern Cast Iron Works By JMCartlidge The authors briefly describe the development and application of cored induction furnaces and their current position in the field of cast iron smelting.The comparisons of the same and different After that, it is proposed that the core-cased electric furnace has the characteristics of high electrical efficiency and small heat loss, together with a stable electric power level which has a small stop-loss and can maintain the height of the liquid level in the furnace so that the core- The ideal holding furnace or dual-use furnace, and give a few examples to illustrate.
