ROTARY CASTING MACHINE TO PRODUCE COPPER WORKPIECE IN CASTING AND ROLLING PLANT Russian patent published in 2017 - IPC B22D11/06 

FIELD: metallurgy.

SUBSTANCE: rotary casting machine contains a frame on which a casting wheel and a tension wheel are mounted, which are covered by endless movable belt that, together with the calibre in the casting wheel, forms a movable crystalliser. The radial section of the crystalliser has trapezoidal shape with upper wide base 15 and a lower narrow base in the form of oblique triangle 17, which three lower corners β₁, β₂, β₃ equal to each other. In the casting wheel grooves an additional cavity 21 with a radius r is made which results in increase of cooling intensity in given area relative to the workpiece.

EFFECT: elimination of defects along cracks in the middle of the lower base of the workpiece trapezoidal cross-section, elimination of workpiece breaks along said cracks during casting and subsequent rolling of the workpiece.
