摘要:
A continuous casting machine is provided with a casting position and at least one preparation position. At least two molds are provided, with each mold connected to a section of a roller apron to form a mold unit which is so mounted that it is movable as a unit between the casting position and a preparation position and vice versa. While metal is being cast through one mold unit at the casting position, the other mold unit at a preparation position may be prepared for use in the next casting operation, including insertion of a dummy bar. When the mold unit is at the casting position, the movable section of the roller apron is aligned with a fixed section of the roller apron, so that the two sections form a continuous guideway for the casting leading to withdrawal rollers.
摘要:
A plate mold for continuous casting machines in which transverse mold walls are carried on yokes which straddle the longitudinal walls and are slidably supported on a frame which surrounds the mold. The transverse walls may be shifted to various positions of adjustment by power operated means mounted on the side walls connected to the yokes. The transverse walls are hinged to the yokes and may be adjusted to any desired angle of inclination.
摘要:
In continuous casting, the cast strand which emerges from the casting mold is conducted through a secondary cooling zone wherein it is guided and supported between latticed guide plates having guide faces which contact areas of the surface of the casting which are supported thereby, and having windows therethrough bounded by said guide faces. The unsupported areas of the surface of the casting which are exposed by said windows are cooled by sprays of cooling water from spray nozzles located in the windows.
摘要:
A guideway for the secondary cooling zone of curved type continuous casting plants in which guide rollers are carried in pivotally mounted yokes adapted to equalize the load on the guide rollers.
摘要:
A built-up plate mold for continuous casting of slabs comprises a supporting frame and longitudinal and transverse mold walls. The transverse walls are normally clamped between the longitudinal walls but can be released for removal and replacement by movement of at least one longitudinal wall. The transverse walls are also clamped to the supporting frame by releasable means operable from the top of the mold so that they may be removed and replaced without removal of the entire mold.
