Abstract:
1. Transport system in a mould-string casting plant wherein the casting plant includes a moulding machine delivering a plurality of uniform mould parts to a string of undivided moulds on the transport system which said transport system transports the moulds (a) from the moulding machine to a pouring station, (b) further on to a solidification and cooling section and (c) to an end at a knock-out station in which the castings are taken out of the moulds, said transport system comprising: a first transport section, in which the undivided moulds in the string are transported slidingly on a first slidingly surface, the sliding transport being provided by the movement of a pressure plate of the moulding machine expelling the moulds from the moulding machine, said first transport section extending from the moulding machine through the pouring station and being free of side rails; a second transport section, in which the undivided moulds in the string are transported slidingly on a second sliding surface from the first section through an initial part of the solidification and cooling section by movable longitudinal side rails, said longitudinal side rails also applying a positive lateral force on each side of the undivided mould string while at the same time moving the undivided mould string along the second sliding surface in an advancing, sliding and longitudinal stepwise manner synchronized with the movement provided by the pressure plate of the moulding machine, and a third transport section, in which the undivided moulds in the string are transported through a further part of the solidification and cooling section which transport is effected by a walking beam system, the walking beam system of the third transport section being free of engaging side rails.
