Hello everyone, I am the youngest girl in the factory.
Is the higher the casting molten iron temperature, the better?
The selection of molten iron temperature should consider the wall thickness, size and grade of the casting.
Generally, the larger the wall thickness, the lower the pouring temperature and the overheating temperature; With the higher the grade, the lower the carbon equivalent and the higher the temperature of the molten iron.
Sometimes, despite the higher pouring temperature of high-grade castings, However, the flow capacity of molten iron is not as good as that of low-grade castings with lower pouring temperature.
The reason is that the latter has a higher degree of overheating than the former.
