Overhead plants are usually set up in groups consisting of several furnaces. The furnaces are charged from below. The charging machine moves under the furnace on a rail system and transfers the charge from a defined transfer station to the furnace.
The furnaces can be charged by means of a scissor lift table or a cable system.
Optionally, a quenching bath can also move directly under the furnace for rapid quenching of the charge. Quenching delay times of less than seven seconds can thus be achieved.
