Abstract
A crystallizer and method for casting using the crystallizer. The crystallizer mainly includes a plurality of-position-limiting parts (16) on the inner side of the mould seat (6, 7). The inner side of the position-limiting parts (16) is in correspondence with the external periphery of the mould wall (8-1, 9-1) of the film mould (8, 9). A medium channel (17) with a medium-supplying port (5) at its upper end is formed between the adjacent position-limiting parts (16).
Claims15
A crystallizer for casting low melting point metals and alloys, comprising:
- a base (1),
- an end mould (2),
- mould seats (6, 7) on the end mould (2), and
- film moulds (8, 9), wherein
- a plurality of position-limiting parts (16) are arranged in the inner side of said mould seats, a slot (17-1) being formed between adjacent position-limiting parts,
- the shape of the inner side of the position-limiting parts corresponds with that of an outer periphery of mould walls (8-1, 9-1) of the film moulds (8, 9),
- an inner periphery of the mould walls (8-1, 9-1) corresponds with the outer periphery of a casting,
- the film moulds (8, 9) are fixed on the mould seats so that the slot (17-1) is closed to become a cycle passage of cooling medium through a medium channel (17);
- on the upper end of the medium channel (17) there is a medium-supplying port (5) and the lower end of the medium channel (17) is communicated with a drain pipe (12).
