METHOD FOR PRESSING OXIDE-CARBON PRODUCTS AND CORRESPONDING LAYING OF PRODUCTS IN LINING OF STEEL LADLES Russian patent published in 2021 - IPC B22D41/02 C04B35/04 

FIELD: metallurgy.

SUBSTANCE: method for manufacturing a periclase-carbon fire-resistant product for lining the working layer of the walls and the slag zone of a steel ladle includes dosing, mixing a periclase powder, a graphite-containing component, resin, and moulding a periclase-carbon fire-resistant product in a mould. The products are made in the form of a wedge brick by pressing onto a die at a ratio of the pressing height h to the hydraulic pressing radius R_g less than 1.20 or in the range from 1.22 to 1.25, and installed on the edge relative to the bottom of the steel ladle. The stability of the seam-forming dimensions of the periclase-carbon fire-resistant products in the working layer of the lining is provided by the geometric dimensions of the cavity of the mould.

EFFECT: increase in the resistance of the fire-resistant lining, reduction in downtime of the ladles during repair are provided.
