一、概述自从1958年铸铁水平连铸(以下简称连铸)生产设备问世以来,连铸技术已有了三十年的发展历史。1987年我国出现了第一条试验生产线.同年又设计和制造了我国第一条年产千吨的生产线。连铸产品组织细密、无铸造缺陷与相同尺寸的砂型铸造材质相比,灰铸铁型材的强度提高20～30%以上,球铁型材兼有高强度和高韧性相结合的优点。连铸工艺可
First, an overview Since 1958 cast iron horizontal continuous casting (hereinafter referred to as continuous casting) production equipment since the continuous casting technology has been the development of three decades. In 1987, the first trial production line appeared in our country, and the same year we designed and manufactured the first production line in China with an annual output of 1,000 tons. Continuous casting products with fine structure and no casting defects Compared with the same size of sand casting material, the strength of gray cast iron profile is increased by 20-30%. The ductile iron profile combines the advantages of high strength and high toughness. Continuous casting process can be
