中文摘要：应用Procast软件对发热保温冒口套和冒口套中金属液的温度场进行数字模拟,并分析了发热保温冒口套在凝固过程中的燃烧情况，及其对金属液温度的影响。并对生产实际浇注过程中冒口套的燃烧情况进行观察，发现可通过优化发冒口套中发热材料的分布，可有效地降低发热保温冒口套的生产成本。
英文摘要：Procast software was used to simulate the temperature field of exothermic insulating riser sleeve and the molten metal in it. The combustion state of the exothermic insulating riser sleeve in the solidification process, and its impact on liquid metal temperature were analysed. The combustion state of riser sleeve in actual pouring process was observed, and it was found that optimizing the materials distribution of riser sleeve could effectively reduce the production costs of exothermic insulating riser sleeve.
