Summary of the invention
The utility model is to solve that aluminium ingot rough surface, the purity compactness not high, material that adopts manual method melting aluminium to cause is bad, metallographic structure is undesirable, the problem of bad mechanical property, and a kind of vacuum melting aluminum casting stove is provided.
The utility model is achieved in that it has a workbench, on workbench, be provided with the working chamber, be provided with charge door at the top, working chamber, one side is provided with vacuum port in the working chamber, below the working chamber, be provided with the casting mold discharge chamber, in the working chamber, be provided with tilt pouring mechanism, in bottom, working chamber and casting mold discharge chamber, be provided with crystallizer and elevating mechanism, described crystallizer and elevating mechanism bottom are passed by the casting mold discharge chamber, its special character is: be positioned in the working chamber that tilt pouring mechanism is provided with the crystallization ring with crystallizer and elevating mechanism correspondence position below tiltedly and crystallizer is positioned at the crystallization ring, described crystallization ring is last, under divide body structure and in the crystallization ring, be provided with the spiral water jacket, between crystallization ring upper body and crystallization ring lower body, be provided with electromagnetic attracting device.
Above-mentioned vacuum melting aluminum casting stove, crystallization ring upper body and crystallization ring lower body one side are hinged, and described electromagnetic attracting device is positioned at crystallization ring upper body and crystallization ring lower body opposite side.
Above-mentioned vacuum melting aluminum casting stove, described spiral water jacket are to be made of the helixseal pipe that is arranged in the crystallization ring.
The beneficial effects of the utility model are:
(1) under vacuum condition, the aluminium material is carried out melting, reduced the foster usefulness that turns into of aluminium significantly, improved the purity of aluminium, reduced under the atmospheric conditions pollution aluminium.
(2) by PLC accurately control melting kettle dump angle, topple over the speed that moves down of speed and crystallizer and elevating mechanism and move down distance, aluminium liquid directly is poured onto on the crystallizer and the cooling effect by the crystallization ring when making the crystallization of aluminium liquid radially trace shrink, make the crystallization ring produce microseismic activity by electromagnetic attracting device, the aluminium that constantly solidifies is separated with the crystallization ring, under the situation of cancellation diaphragm capsule, can realize fixed point, quantitatively topple over, and then realize the directional solidification of aluminium.The aluminium monocrystalline compactness that processes is good, metallographic structure is desirable, and mechanical performance is strong, has avoided the adverse effect of direct water-cooling to aluminium ingot performance, quality; Solved the problem that the conventional vacuum smelting furnace can not melting aluminium that adopts again.
