| Abstract Scope |
Based on numerical modelling a prototype FastCast furnace that utilizes novel method for the large-scale levitation melting (LM) and high-yield casting of metals has been designed and built at ALD. The demonstrator is intended for 10 consecutive single-shot castings. The melting starts as the lower end of the vertically oriented Ti-alloy electrode is immersed in the region of two-frequency horizontal and orthogonal electromagnetic (EM) fields. EM fields rapidly melt up to 500 g of material from the tip of the electrode and simultaneously confine the liquid metal in a levitation condition. The electrode is moved up and detached levitated melt can be superheated. After that the melt is released and it falls down under gravity in the awaiting preheated mould. Instantly the mould is accelerated vertically down to catch the melt without splashing and ensure the smooth filling. Experimental results of successful levitation melting and casting campaigns will be presented. |
