本专利介绍了铝及铝合金的连续铸造法,特别是所谓热顶模连续铸造法.连续铸造法是把熔融金属浇注到敞口的结晶器里,结晶器的下端,开始时由底座靠合.底座随着金属的浇注而连续地下降.在正常的连续铸造情况下,对结晶器壁进行冷却,以使与其相接触的熔融金属形成金属硬壳,熔体的液穴面处在结晶器里.为了实际生产方便起见,在工业生产铸锭时,液穴面最好控制在比结晶器底至少高3.8厘米.如果不是在此以下的脱离结晶器后的铸锭表面受到水的直接冷却,
This patent describes the aluminum and aluminum alloy continuous casting method, especially the so-called hot top die continuous casting method .Continuous casting method is to pour molten metal into the open mold, the lower end of the mold, the beginning of the base by the abutment The base descends continuously as the metal is poured in. In normal continuous casting, the mold wall is cooled so that the molten metal in contact with it forms a metallic crust, the liquid surface of the melt in the mold In order to facilitate the actual production, in the industrial production of ingot, the liquid hole surface is preferably controlled at least 3.8 centimeters higher than the bottom of the mold.If not below the mold surface after the ingot is directly cooled by water ,
