BLOOM CONTINUOUS CASTING CRYSTALLISER Russian patent published in 2012 - IPC B22D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to iron and steel metallurgy, particularly, to rectangular section bloom or billet continuous casting. Crystalliser comprises water cooled walls that make its inner cavity. Opposed walls are provided with chamfers made at 5°…7° on length equal to 0.50-0.65 of that of the wall that forms crystalliser inlet cavity. Crystalliser bottom section has gauging section formed by surfaces of four walls and outlet section formed by counter chamfer made at 10°…15° on length equal to 0.15…0.20 of wall length. Crystalliser is fabricated from berillium bronze to ensure high hardness and strength.

EFFECT: higher precision and quality, reduced wear of crystalliser walls.
