传统的4种金属型材——钢型材,铸铁型材,铜及铝型材均可以用连铸方法生产,对于等截面的坯料,如圆形、方形、矩形及其他异形的铸铁型材,可以采用特殊的短结晶器的水平连续铸造方法获得。铸铁连铸在工艺方面较其他材料的连铸问题更为复杂,除了共牲的拉铸工艺外,还有如何保证在激冷条件下不产生白口组织;保证组织的均匀性;在连铸生产条件下保证孕育、变质处理后组织不衰退等特有的问题,使铸铁连铸技术难度增大。正因为这样,世界上铸铁连铸的发展比其他材质的连铸要晚一些。
The traditional four kinds of metal profiles - steel profiles, cast iron profiles, copper and aluminum profiles can be produced by continuous casting method, for the cross-section of the billet, such as round, square, rectangular and other shaped cast iron profiles, you can use special Short mold horizontal continuous casting method. Casting of iron in the process of casting than the other materials more complex issues, in addition to alchemy casting process, but also how to ensure that in the chilled conditions do not produce white tissue; ensure the uniformity of the organization; in the continuous casting Under the conditions of production to ensure pregnancy, metamorphic tissue does not decline after the peculiar problems, so that casting iron casting technology more difficult. Because of this, the development of cast iron continuous casting in the world is later than that of other materials.
