Abstract (en)

[origin: EP3878572A1] To increase the number of times a mold for continuous steel casting having dissimilar material-filled portions formed therein can be used significantly as compared with that in conventional molds. The mold 1 for continuous steel casting according to the present invention includes: a mold plate 21 made of a copper alloy and having a front surface forming an inner wall surface of the mold and a back surface on which a cooling water channel 31 is formed; and a backup plate 23 attached to the mold plate so as to cover the cooling water channel. A dissimilar material-filled portion 22 filled with a dissimilar material having a thermal conductivity different from the thermal conductivity of the mold plate is formed in a recessed portion that is formed on the front surface of the mold plate and located in a region including at least a meniscus. A water stream disturbing portion 32 is formed in the cooling water channel on the back surface of the mold plate. The water stream disturbing portion disturbs a water stream, increases the surface area of the cooling water channel, and is formed in a region corresponding to the region in which the dissimilar material-filled portion is formed.
