Description
Technical field
The invention belongs to casting of metals technical field is and in particular to arrive a kind of controlled micro metal of new liquid level rate of climb and alloy cast ingot and foundry goods casting system.
Background technology
In the casting of micro metal foundry goods produces, the selection of Casting Equipment and method should take into full account the construction featuress of ingot casting and foundry goods, the feature of cavity filling process and casting system, selects suitable casting device and method, reduces casting flaw as far as possible.Conventional casting method has top pouring type and two kinds of bottom filling.
The ingate of bottom filling casting method is located at foundry goods bottom, and molten metal injects casting mold from cavity bottom.The liquid metal filling of this casting method steadily, will not produce to swash and splashes, scabs, the gas in die cavity is easily excluded from top, metal oxidation is few.Bottom filling casting method also has many defects, the method filling velocity is slow, it is unfavorable for the consecutive solidification of foundry goods, ingate is easily overheated, is also easy to produce shrinkage porosite, poor to the feeding effect of foundry goods, for height, thin foundry goods is also easy to produce the defects such as misrun and holds, more seriously sprue, cross gate and ingate belong to medical disposable material, thus improve casting cost, therefore seldom adopt uphill casting for small-sized ingot casting and foundry goods.
Currently for micro metal ingot casting and foundry goods, conventional casting mode is mainly top pouring type, and the ingate of the method is located at foundry goods top, and molten metal pours into die cavity by top.Top pouring type casting system is simple and compact for structure, is easy to operate, metal consumption is few, and the method can strengthen the consecutive solidification of foundry goods, is conducive to riser feeding, can reduce axial shrinkage porosite and reduce rising head volume it is easy to be full of die cavity.But the method also has many defects：Metal liquid drop is big, big to casting mold bottom impact power, easily washes out casting mold, and during casting, molten metal swashs to splash to be formed on type wall and scabs, and ingot casting or surface quality of continuous castings are poor, and molten metal with air contact area greatly, oxidizable leads to the defects such as oxide slag inclusion, sand holes in addition.
All there is respective defect in the traditional casting method of both the above, be difficult to produce high-quality high performance mini alloy cast ingot and foundry goods.
Content of the invention
