Abstract: | For a 230t large steel ingot which is firstly manufactured in one industrial plant, both of the analytical calculation and the numerical simulation methods were adopted to predict the total solidification time based on their own physical and mathematical models. The results showed that the total solidification time calculated by the analytical method was 46.0 h, and that was 40.2 h by the numerical method. Comparing with the actual stripping time of 45.8 h for the 230t large steel ingot, both of the estimated values agreed reasonably well with the actual one. For the purpose of practical utilization, the analytical method tends to be more convenient rather than the numerical one. This study can provide a kind of reference for the prediction on the total solidification time of large steel ingots. |
