METHOD AND APPARATUS FOR PREPARING A SLAG MELT IN A MEDIUM FREQUENCY INDUCTION FURNACE FOR PRODUCING SLAG WOOL FIBER MATERIALS

摘要

A medium frequency induction furnace, in particular directly employed blastfurnace slag in moltenstate as raw materials. The induction furnace includes an induction coilattached with refractorymaterial tamped inner chamber as upper piece of furnace; and a non-magneticinductive hollowmember dispose below the upper chamber of furnace as lower piece of furnace.The upper piece offurnace and lower piece together consist of furnace chamber for furtherheating and regulating themolten slag materials. An electromagnetic conductive member disposed withinfurnace chamber anda cover on the top of furnace to further improve heating efficiency. Alongwith an outside furnaceshell, a bottom of furnace, water cooling system, feeding charges system andassociated powersupply system. The induction furnace feeding with molten slag for furtherheating and regulating inorder to meet the required temperatures, composition and viscosity forproducing the slag fibermaterials.
