Abstract: A mold comprising mold halves separable along a parting line has a rotating lifting handle carried by one of the mold halves, where the handle rotates between a first position in which it lies generally flat against the mold and a second position in which it extends outwardly from the mold to permit engagement by a lifting hook or the like. By this invention, rotation of the lifting handle from the first to the second position is prevented when the mold halves are separated along the parting line by more than a predetermined distance. Thus the mold cannot be lifted, since the handle cannot be rotated into outwardly extending position to receive the hook until the mold is closed. Additionally, this invention may be used to prevent opening of the parting line between the mold halves when in closed relation, while the handle is in the second position.

Abstract: A mold handling system and method wherein cars are moved along a closed vertical loop. A first elevator positions an empty car adjacent a mold-supply conveyor, whereupon a mold is pushed onto the car, after which the car is transferred into a pre-pour mold storage. The mold-bearing car is then moved onto a second elevator which lifts the car upwardly adjacent an elevated pouring deck. As the mold is elevated, a jacket and weight are automatically deposited thereon, and the mold is poured while the car rests on the second elevator. The mold-bearing car is then moved forwardly through a jacket-and-weight transfer station, after which the jacket and weight are automatically removed and recycled back for positioning on another mold arriving on the second elevator. The mold-bearing car is moved through a cooling region, and this is then transferred onto a third elevator which is tiltable so that the mold is dumped from the car.

Abstract: In continuous casting of tubular products, the same die is used with mandrels of different sizes depending on the internal diameter of the tubular product to be cast. This avoids the necessity of dismanteling the casting "set-up" in order to remove a die and mandrel assembly when changing from casting a tubular product of one internal diameter to another of the same external diameter but different internal diameter. The mandrel and die are constructed so that the mandrel is releasable from the die after use to enable another mandrel to be inserted in the same die. During casting, the mandrel is maintained within the die against axial movement either by a thermocouple device positioned within the associated crucible to engage the top of the mandrel. The mandrel may be removed either manually or by a suitable tool engageable with the mandrel.
