Due to the increasing demand for liquid metal deliveries from refiners to shape casting foundries, melt quality topics, which are well known from the aluminum wrought alloy sector, are becoming more and more important.
Long distance transportation of liquid metal alloys requires superheating to compensate temperature loss and to avoid any solidification. After arrival, the transport ladles sometimes replace holding furnaces or have to wait for metal transfer into the holder. Therefore the liquid metal must be heated at destination. Foundry managers can choose between gas burners and ceramic immersion heaters. So far, there hasn’t been a detailed scientific investigation of the influence of both heating technologies on melt quality criteria.
This paper examines the influence of heating technologies at constant holding temperature on inclusion and hydrogen content, density index, as well as chemical composition. The experimental work has been carried out on the alloy AlSi7Mg and AlSi9Cu3(Fe).
