The transportable bale-out furnaces of the TM product lines were developed especially for use at different pouring locations. The cylindrical, very stable furnace housing, the very high-quality insulation and the meander-shape heating elements are the special features of this furnace family. The furnaces are designed to be transported by forklift truck and come with a plug-in connection to the control gear. With a forklift truck the furnace can be transported to the pre-melt furnace for filling. Due to the filling of the bale-out furnace directly at the premelting furnace, the otherwise necessary intermediate transport by means of a transport ladle and an additional filling process can be omitted. This has a positive effect on both energy efficiency and melt quality.
