Abstract (en)

[origin: EP2620236A2] Open-ended mold comprises: an inner tube (2), which is open on both sides, and forms a mold cavity along a longitudinal axis (3); a number of cooling slots (5) arranged in at least one outer surface of the inner tube; a cuff (7) enclosing many cooling slots in a lateral surface of the inner tube; and an outer tube enclosing the inner tube and the cuff in a fluid tight manner, such that a cooling jacket is formed between the inner- and the outer tube. The cuff completely encloses the inner tube in a plane normal to the longitudinal axis, and the cuff is connected with the inner tube by joining. Open-ended mold comprises: an inner tube (2), which is open on both sides, forms a mold cavity along a longitudinal axis (3); a number of cooling slots (5) arranged in at least one outer surface of the inner tube, extending over a length portion of the inner tube parallel to the longitudinal axis; a cuff (7) enclosing many cooling slots in a lateral surface of the inner tube transverse to the longitudinal axis, such that a cooling fluid flows in a cooling slit between the inner pipe and the cuff; and an outer tube enclosing the inner tube and the cuff in a fluid tight manner, such that a cooling jacket is formed between the inner- and the outer tube. The cuff completely encloses the inner tube in a plane normal to the longitudinal axis, and the cuff is connected with the inner tube by joining. An independent claim is also included for a continuous casting machine comprising the above open-ended mold, where a meniscus of liquid metal melt is arranged in the longitudinal region during operating the open-ended mold.
