Abstract
The invention discloses a double-fluid composite iron-based bimetal casting method. The melting point of metal of a first layer is not lower than that of metal of a second layer; after the metal of the first layer is poured, a low-carbon steel chiller is used for fast cooling; after cooling is conducted to obtain a certain temperature, the metal of the second layer is poured, and the pouring temperature of the metal of the second layer is not lower than the melting point of the metal of the first layer; and fusion of the metal of the two layers is ensured. Due to the fact that the chiller fast cooling method is adopted, the fusion amount of the metal of the first layer is reduced, components of the metal of the second layer are ensured, and a bimetal composite workpiece with metallurgical bonding is obtained. According to the technological method, the fusion amount of the metal of the first layer is reduced, the components obtained after fusion of the metal of the second layer are ensured, the double-fluid composite qualification rate is increased, and industrial mass production is facilitated.
