LINER HIGH-SPEED CONTINUOUS-CASTING CRYSTALLISER Russian patent published in 2008 - IPC B22D11/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. The continuous-casting crystalliser incorporates a square or rectangular liner with funnel-shaped top. The bulges and rectilinear side sections nearby rounded off corners are arranged on the walls of the funnel-shaped part section. The bulge height at the distance of 0.5-0.9 of the funnel-shaped part height diminishes in monotony on the casting side. In the lower zone with the height of 0.1-0.5 of the funnel-shaped part, the bulge height diminishes curvilinear to zero on the boundary with the forming part located below the funnel-shaped part. The taper of rectilinear side parts makes 1' 1 -2.5 %/ m. The liner forming part has the walls with a rectilinear section and two taper sections. The upper part features a taper of 0.6-1.2%/m, while that of the lower one is equal to 0.3-0.8%/m. At the distance from the lower end face of 0.1-0.5 of the liner length, funnel-shaped space section diagonal is a constant.

EFFECT: increase in uniform heat removal from the hardening ingot is ensured, ingot deformation is decreased and angular fractures in ingots are eliminated.
