Beschreibung
Zusammenfassung:	The invention relates to the technical field of casting, in particular to a synchronous heating casting method for an alloy casting and the alloy casting. The casting method comprises the following steps that (A) a preheated mold shell is placed in a pouring hearth, a heating system is arranged in the pouring hearth, and the heating system is used for heating the mold shell; (B) after the pouring hearth and the outer side of the heating system are filled with preheated magnesia, the mold shell is heated; (C) when the temperature of the mold shell reaches a preset temperature, alloy melt is poured into the mold shell; (D) stopping heating when the temperature of the mold shell is reduced to 10-30 DEG C below the solidus temperature of the alloy; and (E) when the temperature of the mold shell is reduced to 500 DEG C or below, the mold shell is taken out. According to the method, mold shell heating and melt pouring solidification are carried out at the same time, and the melt flowability and the mold filling cap
