Split type steel ingot casting mold
Technical Field
The utility model relates to a steel ingot casting technical field especially relates to a split formula steel ingot casting die utensil.
Background
In the process of casting large-size cast high-temperature alloy, heat-resistant steel and manganese-copper alloy, shrinkage cavities or looseness are easily formed in the central part of a large-size cast ingot due to the limitation of the fluidity of the alloy. The casting temperature has a large influence on shrinkage cavity and looseness of the central part of the large-size alloy ingot.
If the casting temperature is too high, the fluidity of the molten steel can be improved, and the shrinkage cavity and the loose size of the central part can be reduced. However, when the casting temperature is too high, the molten steel can be adhered to the inner surface of the die, so that the demolding is difficult, and the alloy ingot is usually required to be cut, so that the production efficiency is influenced; if the casting temperature is low, the fluidity of molten steel can be reduced, and the demolding of the alloy is facilitated. However, since the fluidity of the molten steel is lowered, a large-sized shrinkage cavity and porosity are formed in the central portion.
It is known that the cause of shrinkage cavities and porosity in the central part of the ingot is: in the process of solidifying the large-size steel ingot, along with the completion of casting of a steel ingot mould, the central position of the steel ingot cannot be supplemented with molten steel due to the weakened fluidity of the molten steel. At present, a heating riser is mainly arranged at the upper part of a steel ingot mould to improve the fluidity of molten steel, so that the upper part of a steel ingot is almost free from looseness or shrinkage cavity. But after the ingot is cut open, there are often large-sized porosities and shrinkage cavities in the center of the ingot. Even if the manganese-copper alloy with good alloy flow property is cast, when a large-size steel ingot is cast, large-size shrinkage cavities or looseness still exist in the central part of the steel ingot.
