摘要： PURPOSE: A method for casting a large steel mass by using hot top is provided to improve the quality of casting by accurately adjusting a temperature of a hot top part. CONSTITUTION: An induction heating coil(2) is installed on an upper hot top part(1) of a mold of a large steel mass. A fireproof tape and powder are applied to the induction heating coil to insulate it. An entire heating time and an intermittent heating time of the induction heating coil is adjusted according to heating condition set by an actual casting or a simulation casting using a computer. After melting steel is filled in the mold, the induction heating coil is heated so that a temperature of the melting steel in the hot top part is maintained until the coagulation process of the melting steel is completed. In this way, a nonmetallic insertion possible to exist in the melting steel is separated, and a defect such as a contraction hole produced by the removal of gas is prevented.
摘要翻译：目的：提供通过使用热顶铸造大型钢块的方法，通过精确地调节热顶部的温度来提高铸造质量。构成：感应加热线圈（2）安装在大型钢质模具的上部热顶部（1）上。将防火胶带和粉末施加到感应加热线圈以使其绝缘。根据通过使用计算机的实际铸造或模拟铸造设定的加热条件来调整感应加热线圈的整个加热时间和间歇加热时间。在将钢填充到模具中之后，感应加热线圈被加热，以保持热顶部的熔融钢的温度，直到熔融钢的凝固过程完成。以这种方式，可能存在于熔融钢中的非金属插入被分离，并且防止了通过除去气体产生的收缩孔等缺陷。
