A cast abrasion resistant hollow ball is formed with a hollow ceramic core that generated no gas during the casting operation. Solid ceramic bars or supports hold the hollow ceramic core in a fixed location at the center of the cast ball during the casting process. There are no open holes or openings in the ceramic supports due to the fact that the hollow ceramic sphere is composed of an inert refractory material which eliminates any gases being generated during the pouring and solidification of the liquid metal in the casting process.
Boulet creux moulé résistant à l'abrasion formé à l'aide d'un noyau de céramique creux qui ne produit aucun gaz pendant le moulage. Des barres de céramique ou des supports maintiennent le noyau de céramique creux à une position fixe au centre du boulet moulé pendant le moulage. Il n'y a ni trous ni ouvertures dans les supports de céramique étant donné que la sphère de céramique creuse est composée d'un matériau réfractaire inerte qui élimine les gaz produits pendant la coulée et la solidification du métal liquide pendant le moulage.
