B RECIPROCALLY OPTIMIZED FORMS OF EXTRUSION CASTING COIL AND IMMERSION DISCHARGE FOR THE EXTRUSION OF STEEL INGOTS D. The invention covers an oscillating shell for the extrusion preferably of thin and normal ingot formats in the size range of 40 - 150 x 500 - 3,300 mm with extrusion speeds of up to 10 m / min using extrusion powder. The shell of the invention with immersion discharge stands out for the following characteristics:. wide concave and flat plates of central symmetry in the direction of extrusion, partially, in central symmetry regime,. superimposed by a funnel, which ensures a uniform thermal current over the entire width of the shell with a predetermined immersion discharge format. These characteristics of the shell in connection with the characteristics of the freely selectable immersion discharge enable them to be realized:. a maximum extrusion rate (for example 24 h),. failure-free ingot surface even at high extrusion speeds and crack-sensitive steel qualities e. a wide adjustment region of, for example, 500 - 1,800 mm with a type of shell.
