Ceramic filter slice To metallurgy mainly, cast the trade, this product is more heavily than the surface area, mechanical intensity high, heat-resisting characteristic that assaults , can be strained and get rid of the metal and liquid impurity in casting the products, reduce the air vent of castings, raise the quality of casting, reduce and cast the cost, raise labour productivity. Main technical indicator (1)the utilization ratio increasing 5-10% (2)casting tired intensity increases by 15.5% (4)spend 1300 fire-resistantly
