When the molten metal of brass alloys is melted and when using the usual method casting, produces dendrite (dentrite) tissue, and thus not acquisition have the brass alloys foundry goods of microcrystallite.Therefore, proposed to be used to obtain to have the various castmethods of the brass alloys foundry goods of microcrystallite, and, proposed a kind of semi-melting alloy casting method as the example.In this casting, wherein solid metal and liquid metal are accompanied by machinery or induction stirring at the alloy (alloy that wherein is in slurry condition is called " semi-melting alloy ") between the liquidus temperature of alloy and the temperature range blended slurry condition form between the solidus temperature to be cooled off and solidifies, and reached when being scheduled to the solid phase ratio before casting, stirring stops.According to this casting, the dendrite that produces in the solid-liquid mixed serum by disjunction, makes the primary crystal solid in this solid-liquid mixed serum become sphere in shape owing to stir.Therefore, can under high solid phase ratio, still can keep mobile.According to this casting, can obtain to have the brass alloys foundry goods (referring to non--patent documentation 1) of microcrystallite.
[non--patent documentation 1] " Fifth Revised Edition of Metal Manual, " is by THEJAPAN INSTITUTE OF METALS, and MARUZEN limited-liability company edits (publishing on April 20th, 1992), the 1041st to 1042 page.
Summary of the invention
The problem to be solved in the present invention
[0004]
Yet, in carrying out the semi-melting alloy casting method that wherein molten metal is stirred,, therefore need to increase device size owing to need under the control temperature of melt metal, stir.Therefore, under some conditions, extra gas may be incorporated in the molten metal.Consider the loss of grinding tool, need to reduce temperature of melt metal.Yet, even when known brass alloys when the semi-melting state is stirred, also can not suppress the generation of dendritic structure fully.Therefore, the remarkable deterioration of molten metal flow finally causes possible casting flaw thus.
The present invention considers the problems referred to above design.An object of the present invention is to provide a kind of raw material brass alloys that are used for casting of semi-molten, described raw material brass alloys can use the preparation of semi-melting alloy casting method to provide the brass alloys foundry goods of microcrystallite by under the situation of not using the means that are used for stirring molten metal.
The means that are used to deal with problems
[0005]
Therefore; in order to be used for disjunction and granulation under the situation of the dendrite of liquid phase not using; improve the flowability of semi-melting brass alloys; even and in order also to produce the brass alloys foundry goods with microcrystallite that does not have casting flaw when at low temperature casting semi-melting brass alloys, the present inventor studies.As a result, found that following (A) is to (D).
