摘要:
The subject of the present invention is an energy-saving charge transport system in the press-furnace line with recovery of heat energy and recovery of electric energy. Its objective consists in introducing a rational management of heat energy and electric energy in the charge transport system along the press-furnace route and by means of a well-thought-out arrangement of transport routes and charging elevators, achieving compact dimensions of the whole transport structure. The essence of the energy-saving charge transport system in the press-furnace line is the heat energy recovery in the area surrounding the furnace and recovery of electric energy used to drive transport elevators. Elevator (1) loaded with hot charge (3) moves downwards. Motor (5) acting as an electric current generator brakes motion of elevator (1) and via controller (7) supplies electric energy back to battery (8); when motor (6) lifts elevator (2) loaded with cold charge (4), then, in large measure, it uses the energy stored in battery (8). The energy-saving charge transport system in the press-furnace line may find wide application in industries where consumption of energy in the course of technological process is a significant issue.
