DEVICE FOR CONTINUOUS CASTING AND DEFORMATION OF FLAT WORKPIECES Russian patent published in 2020 - IPC B22D11/51 

FIELD: technological processes.

SUBSTANCE: invention relates to continuous metal casting. Crystallizer comprises two pairs of walls. Walls of the first pair are made in the form of strikers with a working end face surface, at that at first striker (1) it is executed vertical, and at second striker (2) the working surface contains inclined (5) and vertical (6) sections. Uncooled first striker (1) is fixed and installed on drive shafts (8) with cylindrical bushings (14). Vertical surface of the second pair of walls (7) tightly adjoins the first pair of walls at angle of 90° to the working surface of the first pair of walls to form a cavity in the crystallizer. Eccentric (9) and cylindrical (14) bushings on drive shafts (8) provide for back-and-forth movement of drive shafts towards each other, at that, movable striker has cooling and rotates on eccentric drive shafts towards fixed hammer. Vertical walls (7) move in vertical plane with provision of two cycles of workpiece deformation.

EFFECT: prevention of premature tempering of the melt in the crystalliser and reduction of slippage of the workpiece in the direction of its travel, improvement of the mechanical properties of the workpiece.
