Filtre keki mekanizmas\u0131: Karma\u015f\u0131k k\u00f6p\u00fck seramik yap\u0131, c\u00fcrufu mekanik olarak etkili bir \u015fekilde engelleyebilir. Erimi\u015f metal, karma\u015f\u0131k yap\u0131ya sahip seramik k\u00f6p\u00fck filtreden ge\u00e7ti\u011finde, mekanik ay\u0131rma i\u015flemi sayesinde filtre y\u00fczeyindeki g\u00f6zeneklerden daha b\u00fcy\u00fck kal\u0131nt\u0131lar s\u00fcz\u00fcl\u00fcr ve filtrenin s\u0131v\u0131 metal giri\u015f ucunda birikerek filtrenin bir par\u00e7as\u0131 haline gelir. Filtre y\u00fczeyinde birikintilerin birikmesi artt\u0131k\u00e7a, yava\u015f yava\u015f bir \u201cfiltre keki\u201d tabakas\u0131 olu\u015fur ve bu da erimi\u015f metalin ak\u0131\u015f kanal\u0131n\u0131 daha da daralt\u0131r. Bu nedenle, yeni filtre malzemesinin y\u00fczeyi daha ince birikintileri s\u00fczebilir. Ayn\u0131 zamanda, filtre malzemesinin i\u00e7i de bir filtreleme etkisine sahiptir; seramik g\u00f6vdeyi delen \u00e7ok say\u0131da k\u00fc\u00e7\u00fck delikten baz\u0131lar\u0131 minik yar\u0131klar g\u00f6sterirken, baz\u0131lar\u0131nda ise \u00f6l\u00fc k\u00f6\u015feler bulunur. Bu farkl\u0131 de\u011fi\u015fikliklere sahip alanlar, kal\u0131nt\u0131lar\u0131n yakalanabilece\u011fi olas\u0131 yerlerdir ve filtrenin i\u00e7inde de bir \u201cfiltre keki\u201d etkisi mevcuttur.<\/p>\n
Y\u00fczey etkisi: Erimi\u015f metal, karma\u015f\u0131k yap\u0131ya sahip seramik g\u00f6vdeden akarken bir\u00e7ok k\u00fc\u00e7\u00fck ak\u0131nt\u0131ya b\u00f6l\u00fcn\u00fcr; bu da temas alan\u0131n\u0131 ve erimi\u015f metalin i\u00e7indeki kal\u0131nt\u0131lar ile filtre malzemesi aras\u0131ndaki temas olas\u0131l\u0131\u011f\u0131n\u0131 art\u0131r\u0131r.
