蠕墨铸铁是介于球墨铸铁与灰口铸铁之间的一种高强度铸铁,是近十几年来发展起来的一种新颖铸铁结构材料。这种铸铁其强度接近于球墨铸铁,并有一定的韧性和较好的耐磨性与导热性,同时又具有灰口铸铁良好的铸造性能,因此引起了国内外有关人士的重视。 处理蠕墨铸铁的困难在于蠕化剂加入量 Compacted graphite cast iron is between ductile iron and gray cast iron between a high-strength cast iron, is developed over the past decade a novel cast iron structural materials. The strength of this kind of cast iron is close to that of ductile cast iron, and has certain toughness, good wear resistance and thermal conductivity, and good castability of gray cast iron at the same time, thus attracting the attention of people concerned at home and abroad. The difficulty in handling compacted graphite cast iron is the amount of vermiculite added
