Definitions
- the invention relates to a method for producing a cast component.
- the present invention relates to the production of components made of an intermetallic titanium-aluminum material, in particular the manufacture of gas turbine components, using a casting method.
- molds so-called casting molds
- the casting molds have an inner contour which corresponds to the outer contour of the component to be manufactured.
- permanent casting molds In principle, in casting processes, a distinction is made between those working with lost casting molds and permanent casting molds. In casting processes that use lost casting molds, only one component can ever be produced with one casting mold. In casting processes that use continuous casting molds, the casting molds can be used several times. Among the casting methods that work with lost molds, among other things, the so-called investment casting. In the casting processes which work with permanent casting molds, reference is made here by way of example to the casting of ingots.
- the rod-shaped Halb ⁇ stuff for filling a crucible spark erosion or comminuted by Wasser ⁇ jet cutting wherein the inserted into the crucible amount of the rod-shaped semi-finished product is tuned to the Schmelztiegelterrorism.
- the present invention is based on the problem to provide a novel method for producing a cast component.
- This problem is solved by a method according to claim 1.
- the method comprises at least the following steps: a) providing a crucible; b) providing a semifinished granulate of a titanium-aluminum intermetallic material; c) filling the crucible with the semi-finished granules, wherein the amount of semifinished granules filled in the crucible corresponds to the amount required for casting the component; d) melting the semi-finished granules of the intermetallic titanium-aluminum material in the crucible; e) providing a mold; f) filling the melt into the mold; g) solidification of the melt in the mold; h) detachment of the cast part from the casting mold.
- a semifinished granulate made of an intermetallic titanium-aluminum material for the manufacture of an intermetallic cast component.
- the granulate form offers considerable advantages over the rod shape known from the prior art.
- a semifinished product in granular form is more flexible to handle.
- a continuous melting and casting operation can be established by using a granular semifinished product.
- a crucible is filled with the semifinished granulate in such a way that the quantity of semifinished granulate filled in the crucible corresponds exactly to the quantity required for casting the component.
- the filled in the crucible amount of semifinished product is therefore not tuned as in the prior art on Schmelztiegelshirts, but rather on the component to be produced. This results in significant cost advantages.
- the procedure is such that a crucible is provided in a first step.
- a semi-finished granulate made of an intermetallic Ti ⁇ tan-aluminum material is then provided.
- the procedure is such that titanium oxide and aluminum oxide are used in a reduction process using magnesium and / or calcium to formulate powders, namely titanium powder and aluminum oxide. powder, be reduced. Subsequently, the reaction products magnesium oxide and / or calcium oxide are removed from the aluminum powder and titanium powder or separated, in particular sieved. The aluminum powder and titanium powder are then ground and heat-treated at a temperature which is below the melting temperature of aluminum and titanium. As a result of the solid state reaction associated therewith, the titanium powder and aluminum powder are converted into an intermetallic titanium-aluminum granulate (Ti x -Al ⁇ granulate).
- the crucible provided is filled with the semi-finished granules, wherein the amount of semi-finished granules filled in the crucible exactly the amount required for casting the Bau ⁇ part to be produced equivalent.
- the semi-granulated product is kept ready in boxes arranged above the crucible.
- at least one of the cheeses is opened and emptied, in which case the semi-finished granules pass into the crucible.
- the same can be refilled with semifinished granulate independently of the further processing of the semifinished product granulate into crucible and casting mold. As a result, the flexibility of the casting process can be significantly increased.
- the semifinished granulate from the intermetallic titanium-aluminum material is melted in the crucible.
- the crucible is also referred to as a cold wall crucible.
- the semi-finished product melted in the crucible is filled into a casting mold as a melt, the melt being melted in the casting mold. solidified and then the cast component
- the mold solidified and then the cast component
- the method according to the invention is preferably used in the production of gas turbine components, in particular in the production of blades for aircraft engines, from an intermetallic titanium-aluminum material.
- the quality of the components produced by casting technology from the titanium-aluminum material can be significantly increased.
