Grafit k\u00fcreselle\u015ftirme i\u015fleminin bir yan \u00fcr\u00fcn\u00fc olan viskoz magnezit-silikat c\u00fcruflar\u0131 nedeniyle, sfero d\u00f6k\u00fcm i\u00e7in kullan\u0131lan kanal sistemi ve c\u00fcruf sistemlerinin normalden -100 daha uzun ve daha a\u011f\u0131r oldu\u011fu bilinmektedir.
\nBu nedenle, sfero d\u00f6k\u00fcm yaparken d\u00f6k\u00fcm par\u00e7as\u0131n\u0131n k\u00fctlesinin kal\u0131ptaki metalin k\u00fctlesine oran\u0131 yaln\u0131zca 50-60%\u2019dir.

Bu nedenle, d\u00f6k\u00fcmlerin ortalama verimi ortalama olarak 45-55%'dir.<\/p>\n
