Abstract

Abstract

In order to obtain the reasonable process parameters in the vertical continuous casting of large diameter Ø260×Ø80 C70600 cupronickel alloy hollow ingot, the effects of the processing parameters on the temperature field and stress field were quantitatively analyzed by using numerical simulation. The results show that the sump depth increases by 10 mm when the casting temperature increases by 20 ℃, and the sump depth increases by 20 mm when the drawing speed increases by 10 mm/min. The sump depth decreases with the increasing of cooling strength of the graphite core tube. Based on the orthogonal test and variance analysis: F_A > F_0.01(3, 3), F_B > F_D > F_0.1(3, 3), F_C < F_0.1(3, 3), therefore, the sump depth is extremely sensitive to the drawing speed, the sump depth is not sensitive to the drawing speed primary cold strength. According to the simulation results, the reasonable processing parameters are as follows: primary cooling strength of 24 m³/h, drawing speed of 80 mm/min, casting temperature of 1 280 ℃, and air cooling for core tube, on this basis, the C70600 cupronickel alloy hollow ingots were successfully produced.
