Continuous casting machines.

摘要

Continuous casting machine of endless track type includes a plurality of mould blocks (1) connected together to form two endless tracks (2,3), the two tracks having respective opposed parallel runs which together define a mould cavity. In use, the mould blocks in the two runs are moved in the same direction and molten metal is introduced into the upstream end of the cavity and the casting (6) is removed from the downstream end. Each mould block has a plurality of cooling passages (7) which extend through it perpendicular to the direction of movement. At least one coolant pipe (8,9) extends beside the mould blocks of each run and a plurality of nozzles (10) communicate with each coolant pipe and are so arranged that, in use, coolant discharged from the nozzles (10) enters the coolant passages (7). Means may be provided to permit coolant to be sprayed from the nozzles only when they are in alignment with the cooling passages or the nozzles may be reciprocated in the direction of movement of the runs so as to increase the time for which the nozzles are in alignment with the coolant passages.
