Pouring Temperature of Cast Steel
Pouring temperature is really important because if the temperature of the molten steel is too low, then the casting is difficult to form, and defects such as failure to pour, cold barrier, and casting inclusions are more like to occur. If the temperature of the molten steel during the pouring is too high, then it’s good for the formation of steel castings, but the crystal grains of the casting are coarse, shrinkage and deformation are likely to occur, and the tendency of decarburization increases.
Pouring Speed
Pouring speed also plays an important part in casting. If the casting speed of the steel castings is too fast, then it is Conducive to the forming of the steel castings, but bubbles and impurities more likely to appear. When pouring thicker castings or using the bottom pouring system, the pouring speed can be adjusted to fast and then slow to reduce the shrinkage of the casting. For thin-walled small parts, the pouring speed can be slow first then fast to reduce defects such as inclusions and pores.
