Definitions
- the invention relates to a method for producing a Casting made of aluminum plain bearing alloy with proportions Zinc, copper, magnesium, silicon and lead as well as such Casting itself.
- a plain bearing alloy is for example, that of the applicant has long been under the Trade names KS 961 manufactured AlZn4,5CuMgSiPb.
- This Plain bearing alloy is characterized by high resilience out.
- An increase in lead to improve Emergency running properties, i.e. to increase eating security, has so far not been satisfactorily achieved because with lead contents above 1 mass% in the liquid Melt a phase separation in the form of an excretion liquid lead phase occurs. This segregation at higher
- the aluminum plain bearing alloy is prevented from being lead Training of finely divided lead excretions. A qualitative high-quality plain bearing material has so far not been possible produce.
- EP 0 440 275 A1 proposed one Aluminum alloy containing one or more of the components 1 up to 50 mass% lead, 3 to 50 mass% bismuth and 15 to 50 Mass% indium and one or more of the Components 0.1 to 20 mass% silicon, 0.1 to 20 mass% Tin, 0.1 to 10 mass% zinc, 0.1 to 5 mass% magnesium, 0.1 to 5% by mass copper, 0.05 to 3% by weight iron, 0.05 to 3 % By mass manganese, 0.05 to 3% by mass nickel and 0.01 to 0.3 % By mass of titanium can be cast in continuous casting, where the strand with direct cooling water 700 K / s is quenched.
- DE-A1-43 17 989 discloses a bearing alloy Aluminum base known with 2-8 mass% zinc, 0.1-3 mass% Copper, 0.05-3 mass% magnesium, 0.1-8 mass% silicon and with at least one element selected from the following five alloying elements, 0.1-3% lead, 0.1-2% manganese, 0.1-2% vanadium, 0.1-2% chromium, 0.1-3% nickel (all Dimensions-%). A continuous casting process is not addressed.
- the present invention is therefore based on the object to specify a continuous casting process with which one Aluminum plain bearing alloy with a high lead content can be shed that a flawless casting is obtained. Furthermore, a to produce a Suitable continuous casting can be created.
- this object is achieved by a Continuous casting process with the features of claim 1 and with a continuous casting made of aluminum plain bearing alloy the features of claim 4.
- the aluminum plain bearing alloy is preferably vertical shed.
- the cooling rate is less than 100 K / s achieved in that the alloy or the solidifying Strand not by immediately quenching the strand but by applying coolant to the casting mold is cooled.
- the cooling rate during continuous casting is preferably 20 to 50 K / s.
- the withdrawal speed of the strand is preferably 1.5 to 2.5 mm / s.
- the plain bearing alloy according to the invention is advantageously characterized in that 90% of the drop-shaped lead deposits have a dimension of less than 10 ⁇ m .
- FIGS 1 to 5 show micrographs of different Aluminum plain bearing alloys, which after the were produced according to the invention.
- Figure 1 shows the micrograph of an AlZn4.5CuMgSiPb1.9.
- the Casting furnace temperature was 775 ° C, and the manifold temperature the continuous caster was set to 745 ° C, the Mold temperature to 720 ° C.
- the casting or The withdrawal speed of the strand was approximately 2 mm / s.
- the casting furnace temperature was slightly increased to 780 ° C; the manifold temperature and the mold temperature remained unchanged at 745 ° C or 720 ° C.
- Figure 3 shows the micrograph of a Aluminum plain bearing alloy, which differs from that Figure 1 differs in that it has 3 mass% lead contains.
- the casting furnace temperature was 805 ° C Distribution temperature 765 ° C and the mold temperature 740 ° C. Temperatures have increased since the Demixing temperature in the phase gram with increasing Lead concentration increases.
- Figure 4 shows the micrograph of a corresponding Aluminum plain bearing alloy with 3.7 mass% lead.
- the Casting furnace temperature was 815 ° C, the manifold temperature 775 ° C and the mold temperature 750 ° C.
- Figure 5 shows the micrograph, which after casting the Alloy was obtained according to Figure 4, with 0.2 mass% Tin was alloyed and consequently only 3.6% by mass Contains lead.
- the structure contains a larger proportion finer lead excretions than Figure 4.
- the casting parameters corresponded to those after the above Exemplary embodiment according to FIG. 4.
