The temperature gradient refers to a temperature change rate in the direction of the isotherm line. In the directional solidification casting, the larger the temperature gradient in the furnace is, the more advantageous the growth of the grain size is. There are two methods of increasing the temperature gradient: the first is to increase the maximum temperature, which can greatly increase the manufacturing cost of the equipment, and the temperature bearing capacity of the casting mold shell and the ceramic core is also required to be greatly improved, and some of the temperature bearing capacity exceeds the high temperature limit of the material. It is not easy to go on to increase the maximum temperature in the furnace. The second approach is to lower the minimum temperature. The common cooling method is that the bottom water-cooling copper plate is cooled by circulating water, but the lowest water temperature can only be controlled to be 0 degrees due to the limitation of conditions, the heat of the mold shell and the molten metal is required to be continuously taken away in the working process, and the cooling effect is limited.
