Title:
SCRAP PRE-HEATING AND FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/012655
Kind Code:
A3
Abstract:
The invention relates to a scrap pre-heating and feeding system of a furnace for steel production, having at least one obvious closure and one chute-shaped container comprising a discharge opening and at least one suction opening, as well a furnace system with a furnace and such a scrap pre-heating and feeding system. The front wall of the sliding frame, which is oriented towards the chute-shaped container, comprises a protection strip which borders on said front wall in a downwards direction. The length of the protection strip transverse to the traversing directions of the sliding frame is at least 90 % of the length of the front wall in this transverse direction. Moreover, the distance of the protection strip from the floor in a vertical direction is between 5 % and 25 % of the overall height of the sliding frame. With the present invention, a scrap pre-heating and feeding system, as well as a furnace system are developed, in which the melting process requires little energy and a short time interval between the tappings is achieved.
