为改善钢锭头部保温性能,利用有限元分析软件ANSYS对模铸低合金钢凝固过程的温度场进行了数值模拟。重点讨论了绝热板热导率、发热板生热率对钢锭头部保温性能的影响。结果表明,绝热板热导率符合保温材料的性能指标;将发热板生热率调整为不低于5.185×107 W/m3时能满足钢锭头部保温要求。
In order to improve the thermal insulation performance of the ingot head, the temperature field of the mold-cast low alloyed steel was numerically simulated by the finite element analysis software ANSYS. The effects of the thermal conductivity of the thermal insulation board and the thermal conductivity of the hot plate on the thermal insulation properties of the ingot head are discussed. The results show that the thermal conductivity of the insulation board is in line with the performance index of the insulation material. When the heat rate of the hot plate is adjusted to not less than 5.185 × 107 W / m3, the thermal insulation requirements of the head of the ingot can be met.
