Combining typical testing method and engineering testing method, taking calorific intensity and thermo-plasticity as the index, this paper analyzes the relationship between core's high temperature performance and resist sand penetration and veining, which gives the guide to the practical production. 本文采用经典试验法和工程试验法相结合,以砂芯的热强性和热塑性为指标,分析了砂芯高温性能与抗粘砂和脉纹的关系,并用于指导实际生产。
The influences of some main facters on the temperature field in radiation tube are studied based on the model, including the consumption, the flame length, the calorific value of fuel, and the intensity of surface heat flow. 在此基础上,研究了燃烧量,火焰长度,燃料发热量和辐射管表面热流对管内温度分布的影响规律。
