METHOD OF COMBINED CONTINUOUS CASTING, ROLLING AND PRESSING OF METAL BILLET AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B22D11/06 B21C23/00 

FIELD: metallurgy.

SUBSTANCE: device comprises a rotary crystalliser 3 forming a continuous cast billet 4, a roll 7 with a groove and a roll 8 with a projection forming a working caliber, a die 9 at the caliber outlet, a device 5 for controlling the temperature of the cast billet, guiding elements 6. The upper part of the roller 8 projection 14 has a t-shape, the projections 12 are made on the roll 7 cylindrical surface. There are slots 13 on the roll 8 cylindrical surface forming a labyrinth mating of rolls with projections 12. The die and die holder have mating slots and projections providing fixation of die position. The die is placed in the working caliber with gaps relative to roll surfaces. The billet from mould 3 with a present temperature is rolled in the working caliber and then pressed through a calibrated opening in the die. When the cast billet is fed into working caliber, the cast billet metal is pressed into gaps between the working surfaces of the rolls and the die to form a cladding layer of metal on the roll surface.

EFFECT: reduced roll wear and losses of metal by self-sealing of the groove-projection interface.
