The invention discloses an alloy semi-continuous vacuum casting system and a casting method. The system comprises a cavity body, a graphite ring, a crystallizer, a transfer plate, a control device and a vacuum pump. A chamber for accommodating alloy liquid is formed in the cavity body. The graphite ring is annularly arranged in the cavity body. The crystallizer is arranged on the outer side of the graphite ring. The transfer plate is arranged above the crystallizer and the graphite ring, wherein when the alloy liquid is accommodated in the chamber, the alloy liquid, the bottom surface of the transfer plate and the inner side of the graphite ring surround annular closed space. The control device is provided with a controller, a vacuum degree sensor and a liquid level sensor; the controller is electrically connected to the vacuum degree sensor and the liquid level sensor; the vacuum degree sensor and the liquid level sensor sense the annular closed space; and the vacuum pump is provided with a pipeline penetrating through the transfer plate to communicate with the annular closed space.
Description
technical field [0001] The present application relates to an alloy casting, in particular to an alloy semi-continuous vacuum casting system and a casting method thereof. Background technique [0002] In the aluminum alloy semi-continuous casting crystallizer commonly used at present, the graphite ring of the crystallizer is completely immersed in the aluminum liquid. The height of the graphite ring has been designed during the production of the crystallizer, and the height cannot be changed during production. The graphite ring of the crystallizer is a key part of the primary cooling of the casting process. The effective cooling height of the contact between the molten aluminum and the graphite ring is called the single cooling distance of the mold (hereinafter referred to as MAL) in the industry, and the MAL height is the core parameter of casting quality. Because the solidus of different grades of aluminum alloy is different, the solidus temperature is also different, and t...
