Electromagnetic heating transferring means for steel bars between working stations comprising two dip tanks containing bituminous solutions

摘要

The plant comprises a metal cage or tunnel that develops longitudinally over the entire path from exit of the steel bars from the furnace or from where they are stored, up to the final station, covering two consecutive dip tanks, contained in which is bituminous solution at different temperatures. Said cage carries within it a bell-shaped thermo-electromagnetic device, closed at the bottom by an electromagnetic plate, which is slidingly guided in a suspended way along said cage. The electromagnetic plate defines within the bell a closed top compartment, which is used as chamber for containing equipment designed for heating, and a compartment open at the bottom, which serves as heating chamber for the bars, which are attracted by the electromagnetic plate and are carried by the bell to the various operating stations.
