Abstract
A kind of hollow steel-ingot casting mould tool, comprises a base, the external mold of a hollow and the core of a hollow, and described core and external mold to be sealed on base and core is placed in external mold inside along common central axis direction.The utility model is by arranging the core of hollow, and the steel ingot of final casting is hollow morphology, and in cooled and solidified process, center is more consistent with edge portions radiating efficiency, prevents surface of steel ingot from occurring crackle.
Description
Technical field
The utility model relates to a kind of steel ingot casting mould, particularly relates to a kind of hollow steel-ingot casting mould tool.
Background technology
At present, steel ingot is in casting cycle, and the heat radiation of molten steel core is slower than edge portions, and this can cause producing stress in molten steel cooled and solidified process, finally causes surface of steel ingot to occur crackle.
Utility model content
In view of this, the utility model provides a kind of hollow steel-ingot casting mould tool, molten steel core in steel ingot cooled and solidified process can be made more consistent with edge portions radiating efficiency, prevent surface of steel ingot from occurring crackle.
Hollow steel-ingot casting mould tool provided by the utility model, comprises a base, the external mold of a hollow and the core of a hollow, and described core and external mold to be sealed on base and core is placed in external mold inside along common central axis direction.
The beneficial effects of the utility model are: the utility model is by arranging the core of hollow, and the steel ingot of final casting is hollow morphology, and in cooled and solidified process, molten steel core is more consistent with edge portions radiating efficiency, prevents surface of steel ingot from occurring crackle.

Detailed description of the invention
As Figure 1-3, the hollow steel-ingot casting mould tool that the utility model provides comprises the core 3 of external mold 2, hollow of base 1, hollow.
First embodiment
Below the hollow steel-ingot casting mould tool 100a of the utility model first embodiment is introduced in detail.
Base 1 one aspect and core 3 and external mold 2 form the seal chamber holding molten steel jointly, therefore, can arrange the first groove 11 and the second groove 12 on base 1, to be fastened on respectively bottom core 3 and external mold 2 in first groove 11 and the second groove 12 and with its sealing; Base 1 provides the casting soup road that soup enters in addition on the one hand, therefore, base 1 between core 3 and external mold 2 is provided with through hole 13, so, by pouring into molten steel from the bottom to top by 13, molten steel core 3 and external mold 2 jointly formed hold molten steel seal chamber in slowly rise, distribution more all with, prevent from sputtering.Preferably, base 1 inside is provided with horizontal soup road 14, through hole 13 and horizontal Tang Dao 14 UNICOM.
External mold 2 mainly play heat radiation and auxiliary steel ingot shaping, seal with base 1 bottom external mold 2, profile can require design according to the concrete shape of steel ingot.Preferably, the upper and lower end face internal diameter of described external mold 2 is equal, so can improve the Available volume of hollow steel ingot.Can imagine and obtain, described core 3 overhead height is higher than external mold 2 overhead height.So, external mold 2 height space can be utilized as far as possible, core 3 overhead height, higher than the part of external mold 2 overhead height, is also beneficial to heat radiation more.
It is shaping that core 3 one aspect plays auxiliary steel ingot, and core 3 and external mold 2 are sealed on base 1 along common central axis direction, and profile can require design according to the concrete shape of steel ingot.In the present invention, the upper and lower end face external diameter of described core 3 is equal, so can improve the Available volume of hollow steel ingot; Core 3 plays heat radiation on the other hand, and therefore, core 3 is preferably set to the column of hollow, and hollow space can lead to circulating cooling fluid, to regulate steel ingot cooldown rate, thus ensures that the line of solidification on steel ingot end face mediates as far as possible.
Improve as to one of the present utility model, described hollow steel-ingot casting mould tool 100a also comprises a hollow tube 4, described hollow tube 4 be fixed on core 3 inner and and be provided with hole 41 between core 3, gap 42 is provided with bottom hollow tube 4 and between base 1, so, pass into cooling fluid by hollow tube 4 to core 3 inside, cooling fluid flows out through the gap 42 between hollow tube 4 and base 1 and the hole between hollow tube 4 and core 3 41.Concrete, weld hollow tube 4 and core 3 by reinforcement 43, the height of hollow tube 4 is higher than the height of core 3.
Improve as to one of the present utility model, described core 3 outer wall is provided with heat-resistant layer 5, and so, heat-resistant layer 5 is between core 3 and the steel ingot after solidifying, and facilitates steel ingot and core 3 demoulding.Based on same consideration, as shown in Figure 4, described external mold 2 inwall also can arrange heat-resistant layer 5.
Second embodiment
Below the hollow steel-ingot casting mould tool 100b of the utility model second embodiment is introduced in detail.
As shown in Figure 4, the hollow steel-ingot casting mould tool 100b of the utility model second embodiment is substantially identical with the hollow steel-ingot casting mould tool 100a structure of the first embodiment, difference first is the design in soup road 14, horizontal soup road 14 is provided with, through hole 4 and horizontal Tang Dao 14 UNICOM bottom hollow steel-ingot casting mould tool 100b base 1.
By the hollow steel-ingot casting mould tool adopting the utility model to announce, steel ingot center in cooled and solidified process is more consistent with edge portions radiating efficiency, can effectively prevent surface of steel ingot from occurring crackle.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
