Description
Technical field
The utility model belongs to metal alloy Casting Equipment technical field, relates generally to a kind of hollow ingot casting two section type crystallizer, is used for the vertical casting hollow copper alloy casting ingot.
Background technology
At present, the crystallizers of centreless that adopt are cast the solid copper alloy cast ingot more in the copper alloy casting.If want the casting hollow ingot casting, must design the crystallizer of new structure, in order to adapt to the production of hollow ingot casting.The technology of casting hollow copper alloy casting ingot is now domestic actually rare, and the technology of horizontal casting hollow ingot is only arranged, and this technology can not be cast the hollow ingot casting of big specification.
Realize the production of the hollow ingot casting of large size copper alloy, crystallizer is the difficult point and the key of technology.Because big specification hollow copper alloy casting ingot discharges a large amount of heats in the crystallization cooling, it is very important in time to cool off, take away heat.Hollow ingot crystallization cooling is shunk fast, the liquation supply is timely in order to solve, the drop-down continuous core print of moulding, interior tissue uniform crystal particles zero defect, the technology and the quality problems of three aspects such as the no knurl scar in surface, need be in conjunction with the foundry engieering reality of hollow ingot, development is fit to produce, satisfy the crystallizer of technology and quality requirement.
Summary of the invention
The purpose of this utility model is to propose a kind of hollow ingot casting two section type crystallizer, make the inside grain refinement of cast metal alloy product, evenly, the intensity and the performance of interior tissue significantly improve, and effectively control the inside and outside blemish of casting hollow copper alloy casting ingot.
The utility model is finished its invention task and is adopted following technical scheme to be:
A kind of hollow ingot casting two section type crystallizer is made of core print member, conventional cylindrical shape crystallizer two parts; Described core print member has the cast pond, and the outside, cast pond is equipped with the metallic sheath of protective effect, and the cast pond is threaded with forming core head top, constitutes the core print member; Described core print member is connected with the clamping of conventional cylindrical shape crystallizer by the cast pond, looping cast chamber between the forming core head of core print member and the conventional cylindrical shape crystallizer; Bottom surface, described cast pond has the sprue gate, and the cast channel connection on sprue gate and core print top, cast passage are poured into a mould chamber with the annular between forming core head, the conventional cylindrical shape crystallizer and be communicated with.
Described forming core head has≤10 ° tapering.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This crystallizer compared with prior art, has advantage simple in structure, easy to operate, that cost is low, result of use is good, can make the inside grain refinement of cast metal alloy product, evenly, the intensity and the performance of interior tissue significantly improve, and the inside and outside blemish of casting hollow copper alloy casting ingot is effectively controlled.
Description of drawings
Fig. 1 is a hollow ingot casting two section type structure of mould schematic diagram.
Among the figure: 1, cast pond; 2, metallic sheath, 3, conventional cylindrical shape crystallizer, 4, forming core head, 5, the cast passage.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of hollow ingot casting two section type crystallizer is made of core print member, conventional cylindrical shape crystallizer 3 two parts; Described core print member has cast pond 1, and the cast pond of present embodiment is that graphite material is made, and cast 1 outside, pond is equipped with the metallic sheath 2 of protective effect, and protection cast pond 1 does not occur chapping under the bigger casting condition of the temperature difference, the safety casting; Cast pond 1 is threaded with forming core head 4 tops, constitutes the core print member; Forming core head 4 is a graphite material; Described core print member is connected with conventional cylindrical shape crystallizer 3 clampings by cast pond 1, and conventional cylindrical shape crystallizer 3 is common cylindrical shape casting crystallizer, during in order to independent use, realizes conventional solid casting.Looping cast chamber between the forming core head 4 of core print member and the conventional cylindrical shape crystallizer 3; 1 bottom surface, described cast pond has the sprue gate, and the sprue gate is communicated with the cast passage 5 on core print top, and cast passage 5 is poured into a mould chamber with the annular between forming core head 4, the conventional cylindrical shape crystallizer 3 and is communicated with.Forming core head has≤10 ° tapering, hollow ingot can shrink to the center in the casting cooling, it is very big to shrink the core power of embracing that forms, straight core print is not easy in casting to bottom knockout, the situation of disconnected core print takes place to embrace in more serious meeting, so the tapering that core print has appropriateness is necessary, in order to guarantee the smooth and straight of hollow ingot inner surface, be not more than 10 ° according to the tapering of experiment situation forming core head.
During use, the core print member is connected with conventional crystallizer 3 clampings, the casting liquation is poured in the cast pond 1, sprue gate by cast pond 1 enters in the cast passage 5 on forming core head 4 tops, in cast passage 5 flows into the annular cast chamber that constitutes between forming core head 4 and the conventional cylindrical shape crystallizer 3, in annular cast chamber, carry out cooling casting, because it is hollow that forming core head 4 has the moulding of constant slope, can be free to slide between hollow copper alloy casting ingot and the forming core head 4, casting draws the ingot resistance less, the casting process moulding is abundant, and ingot quality is good.
