Benefits of the automatic melt transfer
In double-furnace UPCAST® lines the separate melting and holding furnaces are connected with a short airtight launder for the transfer of melt which takes place in batches by tilting the melting furnace with hydraulic cylinders. This operation is performed automatically by the process control system.
By linking automatic cathode charging and melt transfer operations the mass flow in and out of the melting furnace can be optimized and paced in a regular manner saving production costs and improving cast product quality. To prevent the flowing melt from being exposed to the ambient air there is a continuous flow of nitrogen in the launder.
