Solidification Simulation of Large Flat Ingot in different Intensive Cooling Conditions

摘要：

　　The production of huge rectangular ingots becomes crying needs in the condition of lots of heavy plate mills more than 5m have been in operation.In this paper,we simulate the solidification of 60t Q235 huge rectangular ingot with ProCAST in different cooling conditions such as air cooling,forced air cooling and water cooling.The results show that solidification time in forced air cooling and water cooling shortened than that in air cooling respectively by 0.9 hours and 2.2 hours; The primary fine-grain area is large in the forced air cooling and water cooling.In forced air cooling,we can obtain the largest equiaxial crystal ratio and the minimum columnar crystal ratio; The shrinkage cavity position of the ingot in forced air cooling and water cooling is closer to riser than it is in air cooling,but the volumes of shrinkage cavities respectively increased to a greater extent than in air cooling.
