Method for preparing semi-solid alloy rheological slurry or billet through annular-gap type electromagnetic stirring

InactiveCN101745629AAvoid or reduce oxidationStir wellSlurryLiquid metal
A method for preparing semi-solid metal or alloy slurry or billet through annular-gap type electromagnetic stirring is hereinafter referred to as an annular-gap type electromagnetic stirring method in which the liquid metal or alloy liquid with 5-100 DEG C higher than the liquidus temperature is cast in an annular gap formed between an inner side wall of a slurrying chamber and an outer wall of an internal cooling controller. The metal or the alloy liquid is strongly stirred under the action of an electromagnetic induction rotary stirrer. Meanwhile, the cooling medium flowing in an external cooling controller and the internal cooling controller lead the temperature field of the slurry to be more uniform, thereby obtaining the fine and uniform semi-solid structure. The method is characterized in that the width of the annular gap formed between the inner side wall of the slurrying chamber and the outer wall of the internal cooling controller is 3-100mm. During preparation, the cooling medium is flowed in the external cooling controller and the internal cooling controller so as to lead the temperature field of the slurry to be uniform. The preparation method leads the stirring force field and the temperature field of the slurry to be more uniform, thereby obtaining the high-quality semi-solid slurry. The method has the advantages of simple preparation process, convenient operation, excellent shape of the semi-solid structure, uniformity and fineness and low preparation cost, and is particularly applicable to preparation of semi-solid aluminum or aluminum alloy, magnesium and magnesium alloy and other metal and alloy or composite material slurry or billet.
