Title: Cooler guide for moulding belt in continuous casting - has surface formed by dishes with high pressure nozzles
Inventor: LAUENER WILHELM FRIEDRICH
IPC: B22D11/06
Filed: 1977-06-29
Abstract: The running moulding belt in an installation for casting continuous metal ingots, is cooled and guided by directing a cooling fluid through a large number of nozzles towards the face of the belt turned away from the casting chamber. The jets, under high pressure, open into separate dishes, the rims of which are turned towards the belt, and the flow is adjusted so that the coolant fills the dishes and the space between them and the belt completely. The cooling fluid then flows between the rims of the dishes and the belt to be drained off at low pressure. The outlet cross-section from each dish is determined by spacing between the moulding belt and the rim of the dish. In each dish therefore, a hydrostatic pressure acting on the belt is developed, the degree of which depends upon the spacing mentioned. This pressure together with the low pressure prevailing outside the dishes maintains the moulding belt automatically at a practically constant spacing from the rim of each dish. The moulding belt is thus held in the zone of the casting chamber without being retarded and at the same time is guided positively.
