图5. 静态无压射条件下压室中间S5位置第8个循环的反算结果
Fig.5. Typical calculated results of shot sleeve at S5 position during the 8th cycle under the non-shot condition (Tmu, Tmi—temperatures of the metal upper surface and interface; Tsi—shot sleeve surface temperature; T1, T3, T6—measured temperatures at 1, 3 and 6 mm from interface in the shot sleeve; h—interfacial heat transfer coefficient; q—interfacial heat flux density; T3c—calculated temperature at 3 mm from interface in the shot sleeve)
